"When you talk about ideals, a plan in which nobody gets hurt would clearly be the best. But that's...mere nonsense."
Nova , Justice Rage

Nova Tsukuyomi, "The Mighty", is the Sumeragi Group's Defense Unit head, Diva Project leader, and the main antagonist of Azure Striker Gunvolt.

Commanding a number of Sumeragi's top adepts, and bearing mysterious ties to Gunvolt's past, Nova seeks to use the anthem of The Muse, Lumen, in the plan known as the Diva Project, to subjugate Adepts across the country to ensure national security.

Nova has an affinity for the septima Psychokinesis, a power that grants him the ability to control physical matter and energy with his mind. He is tremendously powerful, and rumored to be the most powerful Adept within Sumeragi.

Website Description

A small army of adepts and soldiers serve under this young, charismatic Sumeragi lieutenant. Nova is an enigmatic guy who often speaks in riddles and looks down on others. The scope of his septimal power is largely unknown; however, he is considered the most powerful amongst all the adepts in the Sumeragi Group. He is in charge of a project that, if successful, would give Sumeragi complete control over all of the nation’s adepts under the guise that these adepts are a threat to national security.



Nova is a young, somewhat effeminate teenage boy with red eyes and spiky purple hair, with one white spike. He wears a black Sumeragi uniform with gold, purple and white highlights, gold buttons, a cape, and black shoes with white highlights.

In his Weaponized form, Nova's appearance changes dramatically, not even resembling a human being anymore, instead a warped metallic statue. He is much larger, completely dwarfing other characters. The right side of his body is primarily black, and the other white, with gold highlights on his head. In the center of his chest is a blue and purple orb. He also gains an additional four arms. His voice also has a deep, distorted filter to it.


Nova generally presents himself as a calm and civil person. He is very level-headed, staying calm even when his project is on the verge of failure, and boasts a perceptive, strategic mind to boot. He is also rather polite, thanking Gunvolt for keeping the muse safe, and even offers to pay him, though this is likely in a mocking manner. He also shows extreme loyalty to the Sumeragi Group, believing that only they can bring order and peace to the world.

Nova is also incredibly arrogant, showing great confidence in his abilities. This shows when he apparently puts no effort into his first fight with Gunvolt, and seems genuinely surprised when he notes how strong GV is.

A noticeable aspect of Nova is his strong love for peace and justice, an aspect that has been present since childhood, but has changed due to him experiencing all of Sumeragi's internal conflict causing him to mature in subtle ways and bury his emotions. Everything he does is for the end goal of a peaceful nation, a goal he is willing to do anything to achieve, even brainwashing his fellow adepts. He shows a strong hatred for the "evil" that Gunvolt and QUILL represent, seeing them as terrorists that need to be disposed of.

However, his loathing of Gunvolt is hinted to be a complex about him mastering the Septima that Nova never could, something he seemingly never got over.

After his transformation, Nova's composure all but disappears. His calm, mocking tone is replaced with a frantic, energetic one as he goes on and on about his power. His arrogance increases to the point where he becomes nothing short of delusional, declaring himself to be the ultimate ruler of the world, and that he will bring peace to the planet. At one point, he flat out declares himself a God, and that all life is weak before him, showing how much the Glaives have corrupted Nova's gentle nature and sense of justice.

Nova's more gentle nature is shown through his conversation with Jota revealing that Nova would very much like to do away with Project Muse saying an ideal plan would be one where no one gets hurt. He also voices disapproval towards Sumeragi's treatment toward Stratos and wishes to avoid having other Adepts subjected to the same cruel fate.


Nova was originally an orphan raised in a Sumeragi Adept research institution, and was the 77th test subject in "Project Gunvolt", an attempt to produce artificial Adepts wielding the lightning septima Azure Striker. This was attempted by implanting septimosomes, a bodily factor key to determining septima type and control, in ordinary humans with latent Adept potential. Although Nova was intent on being "Gunvolt" and was predicted to have a higher compatibility level than even Asimov, his lightning went berserk and misfired, to the horror of the observing scientists. Although Nova was able to stop using his Azure Striker, he was critically injured by his own power and left on the verge of death.

Deemed another failure and potential danger to the entire facility, it was immediately decided that Nova's Azure Striker septimosome would be removed before it became permanently bonded to him. Still desiring to make some use of Nova's high potential as an Adept, his septimosome compatibility rates were reevaluated, and Psychokinesis was decided on for him instead. The Psychokinesis septimosome implant saved Nova's life, and he proved to be so proficient with the power that Sumeragi categorized him as a top tier Adept.

Afterwards, showing a talent in both politics and battle, Nova rose to become the commander of Sumeragi's Defense Force, specifically commanding seven other Adepts. At some point before the story, Nova was selected to lead the Diva Project.

Azure Striker Gunvolt

Sinner's Row (Kaleidoscape)

Eventually, the muse is freed by QUILL agent Gunvolt, prompting Nova to begin searching for her.

In Firmament, upon being informed by a soldier that one of his adepts, Zonda, has been defeated, Nova, disappointed, assumes QUILL was behind it. However, he is told that Zonda was beaten by a young boy known as Copen.

Remembering him as Dr. Kamizono's son, Nova dismisses him as a threat, to the soldier's doubt. Nova just states that the world is full of surprises, like Copen, and even hopes that he and QUILL will destroy each other, saving them any trouble. He then demands they focus their attention on finding Lumen.

Capturing the Muse

Sometime afterwards, Nova comes into contact with the escaped test subjectElise. Through unknown means, he seduces her to his side and has her revive his fallen Swordsmen, including Stratos, who is placed under his command. After being informed of the Muse's location, he sends the newly revived Merak to capture her. Merak succeeds and delivers Joule to Nova. Gunvolt however, purses Merak, who sends a Sumeragi tank to face him.

When GV destroys it, Nova contacts him, criticizing him for destroying all his company's "toys". Gunvolt then asks who he is. Nova, relieved he got the right frequency, introduces himself as the commander of all the Adepts Gunvolt killed.

Despite this, he thanks him for keeping his Muse safe, and offers him a reward, asking how large he wants his check. Gunvolt demands that he give back Joule, to which Nova denies, saying she's the center of Sumeragi's project, which is to use her songs to brainwash the world's adepts.

Gunvolt is horrified, but Nova states that brainwashing isn't uncommon nowadays, and that it's something needed to keep their nation safe. He then tells Gunvolt to look forward to Lumen's performance, before hanging up.

Firmament (Idolatry)

Undeterred, Gunvolt heads to Firmament, beating Nova's adepts and Copen once again along the way. Eventually, he comes face to face with Nova, who gladly welcomes him, before showing him Joule, who is hooked up to a machine that gives him total control over The Muse.

Noting that Gunvolt bumped into Copen on the way up, he mentions that Copen's father played a crucial role in developing the tech used for controlling adepts, and that Sumeragi wouldn't be anything without him, making a note to thank Copen. Gunvolt, tired of the conversation, demands Joule be released. Nova just shrugs off GV's antsy attitude, and uses the machine to summon Lumen. Asking Gunvolt if he really thinks he can beat him, Nova uses Lumen to generate a shield for him, before attacking his nemesis.

During the fight, Nova explains that as long as Lumen's shield is up, nothing can hurt him. He also mentions that she is boosting his own septimal power, and marvels at his strength. Lumen weakly calls out to Gunvolt to stop her, but Nova dismisses her, saying she can't do anything.

Gunvolt demands he stop toying with her, to which Nova replies what he does is for peace. He explains that adepts are dangerous, and must be controlled. Gunvolt claims that there must be another way, to which Nova agrees, but states that there is no time. He explains that numerous foreign governments are seeking Sumeragi's tech, and in order for the nation to survive, they must build an army using Project Muse.

Denouncing what Nova calls "just", Gunvolt claims he's only here for Joule, with Nova calmly dubbing him as the evil one, and suggests he lays down until his work is finished.

Eventually, Gunvolt manages to dispel Lumen's shield. Nova, shocked by Gunvolt's power, admits that the latter truly is Sumeragi's greatest creation, only to now say he will actually have to "try" now, before absorbing not only three Glaives, but Joule, in a flash of light that teleports him and Gunvolt into outer space, revealing Nova's monstrous Weaponized form. Nova declares that his Godlike power is for the protection of the nation, and he will crush Gunvolt's wickedness. He then summons his drones, before attacking Gunvolt.

During the fight, Nova explains that The Muse has the power to control minds, while his own septima, Psychokinesis, controls physical matter. With both under his control, Nova declares himself to be omnipotent, and can control adepts all over the world, claiming all are weak before him, and that he will bring peace to the planet. Disgusted, Gunvolt tells him that he has no right to rule over anyone. Furious, he swears to kill Nova to free Joule.

Amused by Gunvolt, Nova promises to deliver divine punishment upon him. However, despite Nova's immeasurable power, he is eventually defeated.

Shocked and horrified as his defeat, Nova bitterly declares that Gunvolt will know nothing but devastation from this point onwards, and warns him that an Adept rebellion approaches, before perishing in a colossal explosion.

Azure Striker Gunvolt 2

Some time after his death, several Sumeragi executives lament Nova's death as it has left a massive hole in Japan's defenses, something that Eden quickly exploits in order to invade the country.

Nova is later mentioned by Xiao Wu, who uses his death as an example of Gunvolt's strength.

Zonda brings up Nova and his "Diva Project" during her fight with Gunvolt, explaining that she took the concept and ran with it, completely merging with Joule unlike Nova, who merely controlled her.

Azure Striker Gunvolt: The Anime

Nova appears hosting a press conference after Gunvolt's attack on Sumeragi's relay station. He gives a statement using the incident as propaganda to prove that Adepts cannot be trusted.

Six months earlier, Nova is backstage with several technicians at a Lumen concert, and tells them to say alert. One asks what it's like for an Adept to hear Lumen's song, but Nova states that, since his septimal powers are contained within a Glaive, he wouldn't know. He then leaves to go to Building One, where Joule is kept, suspecting something bad will happen.

Justice Rage

Nova's Remembrance

The track begins with a young Nova during the Project Gunvolt tests. He attempts to utilize the Septimal power "Azure Striker", but fails horribly and falls unconscious.

Disappointed that Nova has failed, despite his predicated high compatibility, the older scientist orders his assistant to go to find another power to implant in him: the older of them is reminded of the other test subject they have thinking he might have higher probabilities of success.

The track ends on Nova's echoing thoughts, protesting that only he should be given Azure Striker, and that only he can be Gunvolt.

Glaive Wielders

Suddenly, Nova is shaken awake by Jota, who noticed he seemed to be having a bad dream. Nova reassures him, saying he was just reminiscing, and remarks how comfy Sumeragi's cars are. After awhile, they get out and began walking towards their destination.

Noting the worn and damaged environment, Nova wonders if one of the gangs did the damage. Jota dubs it "remains of some past territorial war", caused by adepts who don't realize the point of their powers. He then requests that someone as important as Nova should take note of this.

Nova disagrees, saying he isn't that important. Jota insists that Nova's ideals must be made aware, and that they must quicken Project Muse. However, Nova admits that Project Muse is just the best course of action they have at the moment, and is merely appeasement, going on to say a plan where none are harmed is the best one, being admitting such a plan is rubbish. Jota worries if he said something too presumptuous, but Nova reassures him, saying he's glad to have a supporter like him.

The conversation then shifts to the adept they are tracking: Viper, leader of the street gang Maiden Blood, who almost single handedly defeated the other top gang, L&D. Jota disapproves of Viper, claiming he has no cause, though Nova says that they could still use him. Jota then suggests that Nova leave the work to him, which Nova dismisses.

Nova explains that all high-ranking adepts in the Sumeragi Group, including them, are controlled through glaives. If an adept uses a glaive, it is recorded in the company records. Nova says that he is no different, but reveals that he can still use his septima without using his glaive, to Jota's shock.

Nova urges him to keep it a secret, saying the top brass like to think of glaives as a total control system, and that there are suggestions that sub-glaives should be used. Jota agrees to keep Nova's secret. The latter thanks him, before admitting that he isn't fond of glaives, saying when he transforms, his ego is exposed for all to see, and that he hopes glaives will no longer be necessary if Project Muse succeeds, and that experiments will no longer take place, citing Stratos as an example.

At that moment, the two hear someone calling out Viper's name, and hurry in it's direction.

Flame and Water

Nova and Jota manage to trace the voice to its source, finding Viper and a water adept affiliated with L&D. The L&D adept attacks Viper, only to be swiftly beaten and sent running.

Nova makes himself known and praises Viper, before revealing they are with Sumeragi, and offers Viper a place in the group. Viper refuses and challenges Nova to a fight.


Justice & Rage

Almost immediately, Nova manages to defeat Viper. Furious, Viper begins blaming his septima, saying he never asked for it, and that it's no good.

Nova disagrees, saying that if he joins Sumeragi, his power will have a point. Viper refuses to join, but Nova leaves his business card anyway, then leaves with Jota.

Armed Blue Gunvolt

Track 1 - Rumblings

The track begins with Merak contacting Nova to inform him that a suspicious message was delivered to the Defense Ministry. Nova checks it out, and is surprised to find an informing them of a planned attack on the "Kamishiro", Japan's national barrier, seemingly written by the perpetrators. At first, Nova is tempted to dismiss it as a prank, but then Merak reveals that, after tracing the IP address, that the email is likely from "Eden", the multinational Adept terrorist group. Nova admits they cannot ignore such a threat, being aware of Eden's attacks on other nations, and Merak logs off, awaiting further orders.

Left by himself, Nova briefly on the bold nature of the plan, given Eden's usually stealthy approach, speculating that the attack is merely a front for something. Nonetheless, he presses forward to eliminate the threat, eager to see what Eden can do.

Track 3

Heeding the crime notice, Nova assigned Jota to assist army soldiers in defending the Media Tower, which hosts the repeater Ame no Uzume that generates the barrier. True to their word, Eden attacks by sending in Gibril.

Track 4

With the battle between Jota and Gibril unfolding, Nova contacts Merak. Without a word, Merak immediately deduces that Nova wants him to check the cyber defenses, with Nova being glad that he's so quick on the uptake. This concern was correct, as Teseo had already begun his own assault on the tower's computer system.

Track 5

As Nova oversees the situation, he is impressed by Eden's capabilities, having initially taken them as just an extremist gang. At this time he is personally contacted by leader of The Seven and Eden co-founder Tenjian. Questioned by Tenjian on what he thinks of their performance, Nova admits that he is impressed.

Addressing Nova as a mighty warrior and Adept himself, Tenjian brings up the topic of Adept supremacy, to which Nova replies that he is not interested in "elitism", which Tenjian laments. Nova questions their motives behind this assault, and Tenjian claims they can make an armed intervention any time and that this performance is to display the superiority of Eden's ideals.

Unconvinced, Nova asks him what their real goal here is, and Tenjian repeats his claim. Pressing the subject, Nova asserts that perhaps the flashy show they're putting on is to camouflage something else, although he does not know what.

Changing the subject, Tenjian wonders if Nova means to say there are other conspirators than Eden. He goes on about the implications of this incident becoming public knowledge, with the admitted presence of a real external threat causing said parties to gain power, which Nova agrees with. Tenjian wonders who will benefit the most from this situation.

The conversation ends with both asserting that they will not lose here. After Tenjian hangs up, Nova muses that he is a tough man to deal with.

Track 7

When Gibril briefly stuns Jota and charges towards Ame no Uzume with no one to stop her, Nova thwarts her attack by firing a laser from the satellite Star Dragon.

Track 8

Expressing mild annoyance over having to suddenly deploy the satellite, Nova apologizes to Jota and asks if he's okay. While talking about Star Dragon, Nova brings up that it was disguised as a weather observation satellite and they were trying to hide its military use. Jota admits that he has no excuses, and that due to his failure Nova was forced to deploy a classified weapon. Nova reassures him that the demonstration will make the public realize the danger they face, and serve as a deterrent against anti-Sumeragi forces. Nova praises Jota for his defense, which Jota claims he does not deserve. He also praises Merak for stopping Teseo, which Merak brushes off before claiming he only wants Nova to build an exclusive online game for him or something. Nova laments that it will be costly.

Merak reports his strong suspicion that an unknown third party, not Teseo, was responsible for the barrier briefly going offline. Nova thanks him for the advice, but Merak admits he just doesn't want to be asked to deal with more problems later on. Nova affirms that he expects a good job from him. After Merak logs out, Nova notes that he needs to get rid of the mice, but there's a big affair he has to attend to first...

Track 9

Nova presides over a Sumeragi public announcement about the recent events. Claiming that the attack has made it clear that external threats are a reality instead of fiction, he admits that while they were miraculously able to contain the situation and there were no civilian casualties, they don't know when the threat will strike again.

He then announces that the Sumeragi Group will be taking over national defense management, and expresses their wish to protect the nation from the threat of external enemies.

Other Appearances

Mighty Gunvolt Burst

Nova appears as a collectible pixel sticker in Mighty Gunvolt Burst by clearing the "Full Marks" Challenge by getting an "S" rank in a stage.

Powers and Abilities

As a human artificially attuned to the Septimal stage of the Lifewave, Nova is an extraordinarily powerful adept whom is capable of harnessing the Septima known as Psychokinesis, which grants him the ability to control all physical matter; it's said that Nova's Septima is the absolute strongest and highest ranked among the Adepts in service of Sumeragi, and is said to surpass Azure Striker, the apparent "ultimate Septima", as a pure battling ability, ranking Nova among the most powerful adepts on the planet. Sumeragi considers Nova to be an S+ rank adept, which is the highest rank and the same one assigned to Gunvolt "The Azure Striker" and Zonda.

The might of Psychokinesis turns Nova's thoughts into energy through latent septimal power, distorting all forms of space and matter to achieve the result Nova desires. Even before the Lifewave was uncovered by scientists, abilities similar to Nova's Septima were around, and thus, his Psychokinesis could be classified as the original Septima from which all others seem to be hewn from; being exceptionally powerful and completely matchless, allowing Nova to live up to his title of "The Mighty".

Another indicator of Nova's unmatched Septima power amongst Sumeragi is that even though he had sealed his powers in three glaives, even without weaponizing, he is still able to engage in combat at a level that makes him appear as if he still has his full power and put up a good fight against the likes of an Azure Striker whilst putting no real effort into the fight, albeit while assisted by an outside source; in contrast, the Swordsmen have to undergo the process of weaponization to access their Adept powers.

Interestingly, in the past, when taken in by Sumeragi, Nova was to receive the Azure Striker Septima as utilized by his archenemy Gunvolt and said enemy's mentor, Asimov, and is stated to have a higher affinity prediction than either of them. However, he never manifested the signature control over electrons of the Septima.

Nova's Psychokinesis enables him to fly about unassisted at varying speeds, move a wide variety of objects around with nothing but thoughts guiding them, launch ring-shaped projectiles and orbs in a myriad of formations and direction which seem to home in on his opponents, and even surround himself in a field of septimal energy and charge his opponent to damage them – all this, without using his Glaives.

Nova's Septima is intricately linked with one of the Sumeragi Group's most notable creations, the Special Attack Satellite: Star Dragon (特攻衛星「星辰」, Tokukōeisei – Seishin), which is a satellite that orbits the world. To the public, the Star Dragon is an unarmed satellite that is designed to observe the populace and transmit signals all across the world, but in reality, the Star Dragon could be considered a mechanical monstrosity, equipped with a phenomenally powerful cannon that unleashes a myriad of laser beams upon the earth at potential targets for the conglomerate.

Originally, the Special Attack Satellite was outside of Nova's jurisdiction, and thus, he could not access it – however, a member of Sumeragi whom was loyal to Nova gave the satellite a complete overhaul as to transform it into a weapon of mass destruction which Nova could control through his Psychokinesis.

When weaponized, the Star Dragon's status as a WMD is fully revealed upon his opponents, using his Septima to force the satellite to execute offensive commands by releasing lasers from the heavens that rain down divine punishment like the fists of an angry god. Like every other Adept with a perfect connection with the Lifewave, Nova is able to invoke Skills, which are specialized techniques that make the most of his Septima, accompanied by skill names and elegant haikus.

Nova is unique among the adepts of Sumeragi in that he requires three Glaives to suppress his power to a reasonable level, due to the leaders of the conglomerate being highly fearful of his Septima and deciding to split his septimosome into a trifecta of glaives to properly contain his overwhelming might.

The primary glaive, Ame no Murakumo (天叢雲(アメノムラクモ), Ame no Murakumo lit. Heavenly Plexus Clouds) is known to be a silvery blade, and Yatagarasu (八咫烏(ヤタガラス), Yatagarasu lit. Eight-Legged Crow) and Kurohyō (黒豹(クロヒョウ), Kurohyō lit. Black Panther), his secondary Glaives, are white and black respectively.

Nova's Glaives are unique amongst the other models used by the Swordsmen in that they're tools that never existed previously, being completely artificial and modern in nature, built from scratch to properly contain Nova's immeasurable might.

Using all three Glaives to transform shows the true depths of Nova's Septimal power, enlarging him to the point that the entire final battle takes place on an exposed platform with the curve of the earth below, with Nova becoming a gigantic robotic humanoid monstrosity, a transformation that lives up to Dr. Kamizono's claim of adepts being "monsters".

Showing even greater power in this form, when weaponized, Nova can fire orbs from the sky as usual, but also releasing high-intensity winds and shockwaves, and detaching his extra arms to strike at his enemy independently.

When Nova undergoes the process of weaponization with his trio of glaives, while the Ame no Murakumo stabilizes the transformation, the sub-glaives themselves undergo two individual metamorphoses, with Kurohyō becoming Panther Force (地より這出し陰の化身(パンター フォース), Pansā Fōsu lit. The Shadow's Embodiment Coming Crawling from the Earth) and Yatagarasu evolving into Raven Force (天を往く太陽の化身(レイヴン フォース), Reivun Fōsu lit. The Sun's Embodiment Going to the Heavens), the former becoming a black panther and a white eagle, respectively; these mechanized critters act as septima-driven combat drones, Panther Force lashing out at Nova's enemies with dark energy and Raven Force unleashing light and wind.

Just like Gunvolt and Copen, Nova is able to directly link with the Muse, an elusive and potent Septima which grants those affected by it enormous strength and power amplification by aligning their wavelengths, albeit forcibly on his own end. This grants him the ability to use Joule's Muse ability to project a barrier in order to prevent his enemies from harming or even tagging him, even reflecting bullets towards the one who fired them.

However, Gunvolt was shown to have dispelled the barrier with clever utilization of his Flashfield, albeit only momentarily, with the shield regenerating after a brief moment. In his weaponized form, Joule's barrier envelops the vulnerable core in the middle of his chest, shielding it from harm. Panther Force and Raven Force seem to be involved in the maintenance of this barrier, as Gunvolt was again able to momentarily dispel it by tagging and shocking both drones at the same time.



The room in which Nova's first phase is fought is unique due to its extended width and fully usable walls, allowing for more room to dodge attacks and the ability to jump over Nova with well placed walljumps.

Skill Description
Cybernetic Field
Cybernetic Barrier (Cyber Field)
For the entirety of the fight Nova receives a passive protection barrier using Lumen's power. As long as the barrier remains, Gunvolt cannot tag Nova, and the barrier reflects his tags back as damaging purple needles. The barrier can be dispelled by keeping the Flashfield in contact with Lumen, allowing Gunvolt to tag Nova, though the barrier will regenerate a few moments after Lumen loses contact with the Flashfield.
  • Using a special skill like Astrasphere will temporarily shut down the machine controlling Joule, removing the barrier for some time.
  • The Naga dart can't pierce the barrier.
  • Tags on Nova are removed the moment the barrier regenerates.
Shiden - Nova Strike.png
Body Blow
Nova's standard attack. He hovers down until he is almost touching the ground, then dashes forward at a slight upward angle, covering most of the screen's width. To avoid, jump over Nova during his descent, or during the dash itself with proper timing.
Shiden - Ring Beam.png
Psycho Ring
Nova fires a volley of ring-shaped projectiles. He will either fire three rings at the same height, three rings with the middle ring higher than the others, or two rapid-fire bursts of three rings each. Avoid by being behind Nova when he fires, or by jumping through the rings.
  • The fire formation with the middle ring raised higher than the others can be cleared most effectively with a single dash-jump if you make use of the Flashfield's hover.
Shiden - Machine Aim Bullet.png
Psycho Shot
Nova begins using this attack at battle phase two. Nova flies to the ceiling, at the center of the arena and fires a series of fast-moving orbs aimed directly at Gunvolt. Avoid by moving slowly away from one half of the arena to the other.
  • If you run out of ground to run on, the walls can be used effectively to dodge the final few volleys as a last resort.
Shiden - Bombing.png
Psycho Bombing
Nova begins using this attack at battle phase two. Nova flies high up and dashes from one end of the arena to the other, dropping orbs straight down at set locations. Avoid by dashing in the same direction as Nova, or by standing horizontally between the dropped orbs.
  • Gaps between the orbs will be present both slightly to the left and slightly to the right of Joule.
Shiden - Psycho Fusion.png
Mind Melder
Psycho Fusion
"Ruler from above / hunt your sworn nemeses down / and leave them no quarter! Mind Melder!"

「天が意思、皇の神気 / 仇なす輩を狩り立てん / サイコフュージョン!」

Nova's special skill. Nova spawns a formation of Orbs around Gunvolt. The Orbs appear either in four diagonal directions (forming an "X" shape) or two horizontal and two vertical ("+" shape) around Gunvolt, proceeding to move inwards with Gunvolt needing to jump or walk out according to the shape. The fifth formation will merge into a giant orb after meeting in the center, which will then fly horizontally towards Gunvolt.

  • The Orb formations always follow a "X", "+", "X", "+", "X" sequence.

Armed Phenomenon

Skill Description
Cybernetic Field
Nova's final form has a barrier to protect his core. While it doesn't reflect Gunvolt's needles, it blocks them nonetheless. The barrier will only stay down as long as Gunvolt is constantly shocking both of Nova's combat drones, Panther Force and Raven Force, with the Flashfield at the same time.
Nova Boss Battle (4).png
Divine Wind
Raven Force, the white drone, will lower to Gunvolt's level and start pushing him to the left with wind, trying to knock him off the stage. Falling off results in instant death.
  • The wind effect reaches underneath the edge on the lefthand side of the arena as well, making walljumping to survive an impossible strategy.
Shiden - Darkness Claw.png
Darkness Claw
Panther Force, the black drone, will release a ground-based shock wave that grows in height as it travels. Avoid it by either jumping over it while it's still short, or by leaping off at the right side and hovering with the Flashfield until the shockwave ends at the other side of the platform.
Shiden - Orb Volley.png
Orb Volley
Nova drops three orbs onto the platform, each of which splits into four small orbs that fly in an "X" or a "+" pattern, much like Mind Melder
  • The first orb is dropped at the center of the platform, and the next two are dropped with one on the left and one on the right.
  • The orbs always split in an "X" pattern, then a "+", then an "X", akin to Mind Melder.
Nova Boss Battle (2).png
Star Dragon Lasers
Nova fires energy beams from the Star Dragon satellite to attack Gunvolt. Several vertical orange lightning bolts will crackle for a second or two, then damaging energy beams will appear at their locations. Stay away from the lightning to avoid the beams.
Double Laser - II.png
Double Lasers
Nova begins using this attack at battle phase two. The two drones will each fire a laser beam, one near the ground, one in the air. Avoid by using multi-jumps. It's also possible to avoid by jumping over the lower beam and landing before the upper beam hits, but the timing is tight.
Shiden - Divine Fists 2.png
Fists of God
Nova begins using this attack at battle phase two. Two of Nova's arms release energy pulses on the platform at either side, before two more slam down and unleash a large shockwave. Avoid the pulses by keeping away, and the shockwave by jumping off the edge and hovering back, or by using multi-jumps.
  • The slamming hands will inflict contact damage even after crashing down.
Shiden - Clamator Aethereus 2.png
Clamator Aethereus
The One Summoned (Come), from Beyond the Rumbling Void (Space)
"Emperor and God / Sent from galaxies afar / To punish fools like this! Clamator Aethereus!"

天統べる神の帝 / 銀河の彼方より招来れ天星 / これが神罰 滅びよ愚者よ! 鳴動の虚空(ソラ)、彼方より招来る(きたる)もの!

Nova's final form's special skill. A gigantic fireball is summoned high above the arena as Nova continues his attack patterns. If Gunvolt does not defeat Nova in time, or if he comes into contact with the slowly descending fireball by jumping, it will engulf him, killing him instantly. Lumen's Anthem cannot save him from this attack.

"What's this...? That saddens me... another one of QUILL's grievous deeds I presume?"
Nova , receiving news of Zonda's death

"Nope... He knows how to stir up trouble, but we needn't get involved. He's the lone wolf type, plus he's not even an adept... Just a plain human, with a huge grudge."
Nova , dismissing Copen as a threat

"The world is full of surprises. Sometimes, you get ones like him. It would be nice if he and QUILL would just take each other out for good. For now, focus and bringing Lumen back to me. Our little "project" will be in dire straits without our precious diva."
Nova , ordering the Muse's return

"Phew, thank goodness. Looks like I got the frequency just right. Nice to meet you, Gunvolt. I'm Nova, the guy in charge of all those adepts you wasted. I guess I should thank you though, for taking care of my idol... I would really like to repay you for your kindness. How much vig should I make the check out for?"
Nova , introducing himself to Gunvolt

"Brainwashing isn't really all that uncommon nowadays, you know. But it's something we need to keep our fair nation safe. Not that a terrorist like you would understand such things... Ta ta for now, Gunvolt. Please look forward to Lumen's big performance."
Nova , hanging up on Gunvolt

"Hehe... Looks like he's come to fetch my caged canary. Right Lumen? Or, should I call you Joule?"
Nova , witnessing Gunvolt's arrival to Firmament

"Oh, this gizmo? It gives me total control over The Muse's powers. By the way, you bumped into Copen on your way up here, didn't you? This gizmo is just one piece of the puzzle... Copen's father built the foundation for the tech used to control adepts. Sheesh... Sumeragi as we know it today really is all thanks to him. I'll be sure to thank Copen later."
Nova , on Dr. Kamizono's machine

"Good grief, you're quite antsy. Ah well, whatever. Now, experience exactly what this machine is capable of."
Nova , about to face Gunvolt

"As long as The Muse is here with me, your attacks will do nothing. Not to mention, her powers are boosting my own septimal power... And I'm not even using a Glaive! Her powers are really something!"
Nova , relishing in his power

"I'm shocked, you're... pretty strong. You're indeed our finest creation. Looks like I actually have to try now. It's time for you to see my real power!"
Nova , about to transform

"This Godlike power is for the protection of our nation and her people! My righteousness with crush the wicked!"
Nova , after his transformation

"You see, The Muse has the ability to control people's minds. While my psychokinesis grants me dominance over physical matter. Those are the two building blocks of life. I now control both. I have become omnipotent! With this power, I can control adepts all over the world. Both adepts and humans are all weaklings compared to me now... Under my rule, I will protect the weak and give them peace. That's right... I am the ultimate ruler! The Heavenly Emperor! I - AM - SUMERAGI!!"
Nova , declaring his power

"No! My absolute order cannot be broken...! You imbecile... You are... a... fool... All that awaits you now... is chaos... and destruction... Without order in society, adepts will revolt. The rebellion is coming...!
Nova , in his dying moments

Source: Armed Blue: Gunvolt Complete Works

He’s the bad guys’ boss so I prioritized giving him an elite-like and full of finesse feeling. Him being slender and androgynous is because I wanted him to give off the impression that he’s come this far by intelligence and abilities, and not his strength: that’s where it comes from. I wished his post-transformation form to have a feeling of the strongest and divine, fitting for a last boss, and thus I choose a Buddha statue as a motif. The colors cleanly splitting in the center (of his body) comes from the image of him being like an ultimate existence in which both light and darkness are in complete harmony.

  • Nova's transformation and drones may be inspired by the 1970s manga and anime Babel II, which features a boy and his three servants: A giant humanoid robot named Poseidon, a shapeshifter who prefers the form of a black panther named Lodem, and a pterodactyl-like robot named Lopross.
  • When Final Form Nova uses his special "Clamator Aethereus" skill of summoning a meteor from the skies, he yells "Amatsuboushi yo!" (天津星よ!), meaning "Celestial Ford Star!" In real life, there is a class A supergiant located at an approximate distance of 1,550 light years from Earth known as the Deneb, and the Chinese know Deneb as the Fourth Star of the Celestial Ford (天津四), referring to the Chinese asterism Celestial Ford (天津), formed by Deneb with Sadr (Gamma Cygni), Fawaris (Delta Cygni), 30 Cygni, Nu Cygni, Tau Cygni, Upsilon Cygni, Zeta Cygni and Aljanah (Epsilon Cygni).
  • In the Japanese version, Nova is the only character to have an authentically Japanese name: Shiden.
  • Unlike his Swordsmen, who are each based off one of the Seven Deadly Sins and animals relating to those sins, traits of Nova's personality seem inspired by the sins as a whole, with pride, wrath, envy and greed being the most obvious.
    • Additionally, concept art reveals that Nova once had a much more satanic Weaponized form, being more humanoid and sprouting goat horns. This, coupled with the Seven Deadly Sins motif of the Swordsmen and his particularly strong sense of pride, could suggest that Nova is based off Lucifer, which would make his corresponding animal the goat. This would overlap with Jota, who already represents the sin pride and has a number of other Lucifer traits (light and sun motifs), however.
  • Despite Lumen supposedly being controlled by Nova during his boss fight, her Anthem can still activate.
  • Nova is one of three known participants in Project Gunvolt, the other two being Gunvolt and Asimov.
    • Nova is not only the only one of the three not to join QUILL, but also the only one who didn't receive Azure Thunderclap.
  • Nova's voice actor, Ayumu Murase, is also the Japanese voice of Beck, the protagonist of Mighty No.9, who also has the title "Mighty."
  • Nova is the only known Adept with more than one glaive, with a total of three.
  • Nova's Japanese name "Shiden" means "purple lightning", referencing both his primary colour and his history with the Azure Striker septima. It can also mean "swordflash", possibly referencing the Glaives used by Sumeragi.
    • His last name, Tsukuyomi, is derived from Tsukuyomi-no-Mikoto, a lunar deity in Shinto and Japanese mythology.
  • The names of Nova and his Sumeragi Seven are taken from luxury cars. Nova's name is taken on the Chevrolet Nova.
  • Nova shares several similarities with Copy X, the main antagonist of the first Mega Man Zero game, another series developed by Inti Creates. Both serve as an effective ruler for the masses, with them being a member of the race that they persecute albeit well-intentioned, and they both suffer from an inferiority complex. Their boss battles both take place atop an orbital elevator, both possess a divine-looking second form, and in both second battles the floor becomes smaller and flanked by bottomless pits. Further reinforcing this similarity, during an interview Inti Creates compared ASG1 to the first Zero game, while comparing ASG2 to the second Zero game.
  • Nova's final form also bears a resemblance to Omega from Mega Man Zero 3.
    • Additionally, one of the attacks Nova uses in the first part of the fight, sending out rings of energy for Gunvolt to dodge bears a striking resemblance to one of Omega's two attacks used in the initial encounter.
  • Nova was originally planned to be the CEO of Sumeragi. As Inti Creates felt this was too unrealistic given his young age, he was "demoted" to Diva Project leader when the story was finalized.
  • There is a slightly modified and unused version of Nova's second battle theme in the game's files.
