"That girl's freedom exists only after so many battles."
Asimov , Azure Striker Gunvolt: The Anime

Asimov is a founding member and commanding officer of QUILL, a group dedicated to the freedom of all Adepts and the downfall of the Sumeragi Group, the leader of Team Sheeps, and the endgame antagonist and final boss of Azure Striker Gunvolt.

Although he founded QUILL under the guise of Adept and human equality, his true goal was the extermination of all humanity. He rescued Gunvolt from Sumeragi's experiments and taught him to harness his Azure Striker Septima, earning Gunvolt's eternal gratitude.

He occasionally serves as an operator for Gunvolt after the latter's resignation from QUILL. Like Gunvolt, he has an affinity for the Septima Azure Striker, which allows him to manipulate electrons and control lightning.

Website Description

Asimov is both a founding member of QUILL and the current leader of the group. He is a skilled marksman who is deadly with a sniper rifle.

Although he displays no emotion in the line of duty, his passion for the group’s cause is well known amongst the members of QUILL who look up to him.

Gunvolt owes his life to Asimov, who rescued him from a Sumeragi facility where he was subject to numerous horrifying experiments. To Gunvolt, Asimov is a savior, teacher, and a father figure. [1]



Asimov is a young adult with shoulder-length gray-blue hair and a pair of blue visor-like glasses that serve as limiters. His eyes are purple.

He wears a gray armored long coat with black highlights and arm armor. He also sports white trousers with black highlights over his inner thighs and groin, and black boots with glowing blue highlights.

After removing his limiter, Asimov's hair stands on end and his eyes pulse with a pure, bright light.


As the head of QUILL, Asimov generally keeps an aloof, professional demeanor about him, at least during missions. He takes his duties, and those of others, extremely seriously, and has very little patience when it comes to those who disobey him, showing no stress cutting Gunvolt from the organisation, and even warning him that if he crossed them as an enemy, he wouldn't hesitate to wipe him out. When Gunvolt and Joule refuse to join him once more, he just shoots them and goes about his way.

Very passionate about achieving QUILL's goals, this can lead him to take seemingly cold-hearted decisions, such as ordering the destruction of The Muse even after the revelation that it is not code, but a girl, an Adept girl, who had been held against her will.

Eventually, Asimov's true motives are revealed; to destroy humanity once and for all, as retribution for their crimes. A part of Sumeragi's Project Gunvolt, Asimov was horrifically experimented on, resulting in a deep, burning hatred for humanity. This hatred was so great that he didn't hesitate to kill his protege in cold blood so he wouldn't get in the way.

However, Asimov does have a lighter side to him. He can be surprisingly eccentric at times, showing great interest in Japanese culture and even singing karaoke. Despite his usual stoic behavior, he was extremely close to his teammates, stressing the importance of a close team, and had no qualms going out with them for a good time.

Asimov may be a bit of an alcoholic, as both canon Admiration to Peace artwork and a Thanksgiving promotional wallpaper depict him with multiple empty glasses, and in the latter he is seemingly keeping an entire bottle of wine to himself.

He appears to be somewhat insecure about his age, as in a home conversation Gunvolt claims that Asimov would pout and say "I'm not that old" if he heard Gunvolt call him a surrogate parent. In Admiration to Peace, he mentions that he's still in his 20s when a parent/child comparison is made.

In the Japanese script, he frequently uses English words, with "Good luck" practically being a catchphrase. When confident in victory over an enemy in combat, he also tends to say "Dead end." At times, acquaintances like Joule point out that his English usage is seemingly incorrect, such as him possibly believing the plural of sheep is sheeps. Even Moniqa thinks to herself that his English usage is strange, and wonders who taught him that.

Interestingly, despite his fanatical hate for humans, he was still very close to his human subordinate Moniqa, and acknowledged her as a human who genuinely cared about Adepts, in contrast to other human collaborators who he believes are only in it for their own gain. This makes it uncertain if he would have included her in his planned genocide.

Plot Role

Asimov originally was a waif born from two illegal immigrants. After being captured by Sumeragi’s Hunters, he was discovered to be a "match"--a normal human with latent septimal potential--and potentially compatible with the lightning septima, the Azure Striker, at that. Used as a test subject in Project Gunvolt, he was the first match to successfully be implanted with the Azure Striker septimosome and not be killed by his own new power. However, due to not being able to fully control his ability, he was still deemed defective. His identification name in Sumeragi at this time was “Takefutsu.”

Afterwards, he was subjected to all types of experiments as a lab rat at the Sumeragi Futures Institute of Technology (S-FIT). Leading researcher Dr. Kamizono relentlessly demonized Asimov, openly speaking of the boy as no longer being human while talking to his assistant within earshot of him. As a result, Asimov developed a strong hatred for Non-Adepts.

Upon activating his power during an experiment, he released a massive blast of lightning that completely destroyed S-FIT and killed all personnel--Dr. Kamizono being among the casualties of the incident. All details about this incident were covered up by Sumeragi.

Changing his name from "Takefutsu" to "Asimov", the boy mingled in the confusion and escaped the lab. He somehow managed to escape overseas and joined a certain group, and from then on devoted his efforts to establishing QUILL.

At some point, he and several Adept comrades founded QUILL, an international organization dedicated to the freedom and liberation of Adepts everywhere. Now an adult, Asimov returned to Japan and began conducting raids on Sumeragi facilities. He would eventually rescue another successful product and victim of Project Gunvolt: a nameless child whom he gave the name "Gunvolt", and allowed to join QUILL at the child's own insistence. Asimov acted as a father figure for Gunvolt, teaching him not only how to wield his Azure Striker septima, but also training him in martial arts and firearm usage.

Azure Striker Gunvolt

1st Sumeragi (Muse)

Asimov, along with Moniqa and Zeno, guide Gunvolt through Sumeragi's facility in his vital mission to finally destroy The Muse. After Gunvolt's failed torture session that ends in him discovering The Muse is on a getaway train. Guided by his teammates, Gunvolt makes it to The Muse, and is shocked to find an actual girl named Joule. Gunvolt requests to save her, but Asimov denies, seeing her as a threat to Adepts everywhere, regardless if she is just a poor victim. However, Gunvolt instead goes against his orders and rescues her. As a result, Asimov removes him from QUILL, leaving Gunvolt to fend for himself.

Despite this, Gunvolt and QUILL would still work somewhat closely together over the next six month period.

The Capture of The Muse

After Gunvolt successfully defeats The Sumeragi Seven, Joule is suddenly captured by the revived Sumeragi Swordsmen Merak, who takes her to the space station Firmament to the waiting arms of Project Muse director Nova. To get her back, Team Sheeps launches an assault on the orbital elevator Babel, with Asimov storming the front whilst Gunvolt sneaks aboard. The operation is successful, however Asimov completely disappears after this.

Firmament (Idolatry) - Revelations and Father Figures

After Gunvolt kills Nova and rescues Joule, Asimov reappears as they go to Babel, revealing his intention to use Gunvolt and Joule to destroy humanity, now that Sumeragi has been thrown into chaos. He tries to convince them to rule as king and queen, but the two reject his ideals. Asimov is mildly disappointed, but quickly gets over it and pulls out Copen's gun, "white tiger", revealing he beat the boy on his way up. He then calmly shoots them both and walks back to Babel, leaving the two for dead.

Firmament (Azure) - Patricide

After making to Babel, Asimov begins to take the space elevator back down to Earth, only to have Gunvolt catch up to him, his pendant having spared him from death and Joule, who's consciousness had transferred to Lumen, having granted him tremendous power. Impressed, Asimov removes his inhibiting glasses and attacks his foster child.

After a tense, climactic battle, Asimov kneels over on death's door. Accepting defeat, he asks Gunvolt to accept his destiny, and guide all Adepts to a better future, before dying halfway through his last words.

Azure Striker Gunvolt 2

Asimov's soul and septima would persist in some form after his death, appearing as the Azure Spirits that Gunvolt can encounter within Mysterious Manor and the Data Facility. Contact with these blue glowing orbs causes Gunvolt's Azure Striker to morph and gain abilities he previously did not have, namely the Dragon Sphere and Crashbolt. Gunvolt is not aware that the Azure Spirits are remnants of Asimov.

Other Appearances

Mighty Gunvolt Burst

Asimov appears as a collectible pixel sticker that can be obtained by completing the "Super Sprinter" challenge by clearing the game in under one hour.

Powers and Abilities

As a human artificially attuned to the Septimal stage of the Lifewave, Asimov is an exceptionally powerful Adept who wields the Azure Striker Septima, which grants him the power to manipulate lightning and is said to be one of the most powerful of Septima. As he is the one who taught Gunvolt to control his Septima, he can perform many of the same Skills Gunvolt can, but on a much stronger scale. His Septima is always running wild, requiring him to wear specially designed sunglasses to restrain it.

In battle, he can perform Prevasion, turning his body into electrons to become intangible and allow attacks to pass through him. He can also use the Flashfield, but can do so in a more offensive manner by charging at foes. But if he collides with Gunvolt's Flashfield, it will cause both of them to overheat, leaving him vulnerable.

He can also punch the ground and channel lightning through it. His most powerful attack is the Voltaic Chains skill, where he deploys numerous electrified chains to ensnare and electrocute opponents. With this attack, he was able to nearly kill Copen and destroy his shield.

Apart from his Septima, Asimov is a skilled marksman and firearms user, capable of picking off targets with his E.A.T.R. rifle from great distances. He also shows great mastery of Copen's Voder gun and can use his Septima's ability to create a electromagnetic field to guide the path of Copen's Power Grab bullets so they can home in on enemies. However, this puts a strain on the gun and may cause it to stop working.



They are a safety device used to control his abilities.  

This equipment is the same system as GV’s contact lenses, yet, unlike GV who uses his lenses to increase his Septima, Asimov uses them to seal his own Septima.  

Only a small handful of QUILL members know about these sunglasses’ effect and his Septima because of an ethos within QUILL that says “Don’t snoop others’ Septimas”. 

E.A.T.R (Electro - magnetic Anti Tank Rifle):

An anti-tank rail-rifle provided by QUILL. It’s a gun with command standards, and brother gun to the “Dart Leader” provided to GV.  

The bullet shot from the weapon has an effective range of 5.000 meters and a speed of 7 Km per second: it will always “predate” the target.  

When sniping from very long distances, the user is in need of high skills and precise calculations amongst others.  

Since it isn’t an anti-personnel weapon, he didn’t use it during his battle with GV. 

Greed Snatcher

A special bullet with the property to control others’ Septimas that was stolen from Copen

Asimov also makes use of the Azure Striker ability to create an EM field that allows him to pull a new stunt: freely controlling the path of the bullets. 

But that places a very strong burden on the gun itself and it’s a double-edged sword. It's an ace-in-the-hole that can only be used in a brief battle. 

The Dart Cartridges that GV uses can mechanically control this technique to some extent.


Skill Description
Asimov Battle (1).png
EM Boundary (Heat Haze)
Throughout the battle, it is impossible to tag or even damage Asimov due to his ability to prevade all attacks using the Azure Striker septima. To make Asimov vulnerable to tagging, you must first make him overheat through countering his Flashfield attack. Once tagged, you'll be able to hit Asimov with the Flashfield like normal.
  • If Asimov prevades a shot from the player while tagged, the tags will be removed.
Asimov - Cerberus.png
Asimov's standard attack. Asimov fires two waves of three magnetic bullets, which ignore Prevasion and inflict the Chaff debuff if they connect, freezing Gunvolt's EP at 0 for ten seconds.
  • The attack is based on the Cerberus bolt, which has a maximum of three tags. Likewise, Asimov fires it in intervals of three.
  • Damage Output: 40 per bullet.
Asimov Battle (2).png
Thunder Scales
Asimov's standard attack. He hops up in mid-air and performs a fast air dash while activating his Flashfield.
  • While this attack deals devastating damage, it also offers Gunvolt the opportunity to disable Asimov's prevasion. If Gunvolt activates his Flashfield within the radius of Asimov's, the collision will induce a voltage spike, overheating both Azure Strikers. For a brief moment after the spike, Asimov will be vulnerable to tagging and subsequentially vulnerable to taking damage until the tags disappear.
  • Damage Output: 104.
Asimov - Ground Surge.png
Lightning Sweep
Asimov performs this attack at the beginning of battle phase two and three. He punches the floor, sending a shockwave across the floor.
  • At the beginning of battle phase two, the shockwave will propagate off the screen and then return as a larger shockwave.
  • At battle phase three, the shockwave is initially large and will not return once it is off-screen.
  • If the battle goes on for too long, the shockwaves will continuously go across the floor every few seconds.
  • As all of Asimov's other attacks are based on Gunvolt's own arsenal, the attack's ground-crawling property is most likely a reference to the Technos bolt.
  • Damage Output (Small Shockwave): 32
  • Damage Output (Large Shockwave): 40
Asimov Battle (3).png
Asimov begins using this attack at battle phase two. He fires a non-damaging cursor that leaves behind five non-damaging cursor placeholders in its path of fire. Asimov then proceeds to fire five magnetic bullets that may turn directions to track Gunvolt when it comes into contact with any of the five placeholders; cursor placeholders used in this way will disappear.
  • The homing property of the attack is based on the functionality of the Mizuchi bolt.
  • Damage Output: 40 per bullet.
Asimov - Orochi.png
Asimov begins using this attack at battle phase two. A single magnetic bullet is fired, as well as a bot that hovers to the center of the screen. The bot then fires two waves of seven magnetic bullets in an upward and downward arc curve.
  • The attack is based on the functionality of the Orochi bolt, firing in both its upward and downward arcs.
  • Damage Output: 40 per bullet.
Asimov - Voltaic Chains.png
Voltaic Chains
Voltic Chain
Fear the azure creed / Its thunderous voice the alpha and / Omega of all things! Voltaic Chains!

Asimov's special attack. Several chains are summoned that cover the screen, leaving only a small open space. He proceeds the attack by charging the chains with electricity, dealing massive damage.

  • Due to the gap in chains near the very ceiling, you can also avoid the attack using Anthem's infinite jumping technique or by using a Boost Band.
  • In the Nintendo Switch and PS4 versions of the game, as featured in the Striker Pack, and the updated Steam version, this attack has been rebalanced with more safe zones than in the 3DS release and original Steam version.
  • Damage Output: 350

Designer Comments

Source: Armed Blue: Gunvolt Complete Works

I made him tall and with a well-built body to give out a “reliable leader” (image), and by adding sunglasses I make him express a facet of “he never shows his will (to others)”. I also had in mind “that” American comic hero who’s the leader of a Super-Psychics squad. By the way, (Asimov’s) sunglasses are military stuff and bullet-proof. At the beginning (of the designing process) I drew a draft in which he was older, had short hair and a stubble but, taking into mind female reception (of the character) I turned him into a long-haired and effeminate man-style (character).

  • Asimov's code name as a test subject, Takefutsu, comes from Takefutsu no Kami, which is another name for Takemikazuchi, a Japanese thunder god.
  • The notes in Asimov's concept art reveal that he is from America, but unlike other foreign characters such as the members of Eden, no profile materials elaborating on Asimov's background mention his national origins, only that he is the waif son of illegal immigrants in Japan and was captured when he was a teenager or even younger. His frequent usage of English is also noted to be incorrect at times, and the ASG2 OST booklet timeline implies that Asimov might not even be his real name, listing it with quotes and as something he switched to from his old code name Takefutsu.
  • Asimov's English voice actor for the OVA, Maxwell Powers, also provides the English voiceover for the Azure Striker Gunvolt game trailers. He is also the presenter of Neo Geo mini from SNK.
  • Asimov is one of three known participants in Project Gunvolt, the others being Gunvolt and Nova.
  • Out of all named Adept characters, Asimov is chronologically the oldest, at 24 years old as of ASG1.
  • Asimov happens to navigate the missions with bosses (Jota and Viper) who appear in the Azure Striker Gunvolt demo.
  • When Asimov kills Gunvolt with Copen's Power Grab, he says, "Hasta la vista, GV." This is a reference to the scene in Terminator 2: Judgement Day when T-800 shoots a frozen T-1000 with a pistol and says, "Hasta la vista, baby".
  • During the events of Firmament (Azure), some of Asimov's blood stains the gun he stole from Copen. It is this blood that allows Copen to copy the Azure Striker septima and gain access to its abilities, such as Prevasion and Flashfield.
  • In the Drama CD track, Ninja Arts, it is revealed that Asimov is a huge fan of ninja culture. It also seems that Moniqa is the only Non-Adept that he believes is sincere in helping Adepts and appears to care about her to an extent.
  • At 350 points of damage, Asimov's Voltaic Chains was the most powerful normal attack in the series prior to Luminous Avenger iX, where it was surpassed by EX form Crimm's Exquisite Artillery.
    • However, Exquisite Artillery does not ignore Prevasion like Voltaic Chains does.
  • There is an unused remix of the Sumeragi boss theme in the game's files that was seemingly intended for Asimov at some point. Their normal themes are listed as GV_BGM_015 and GV_BGM_019 respectively, while the unused theme is listed twice as GV_BMG_015a and GV_BMG_019a. 
  • Asimov is one of three antagonists who called Gunvolt GV, the others are Zonda and Teseo. Coincidentally, all three are final bosses.
