"Those bastards don't care who they hurt!"
—Xiao Wu , Azure Striker Gunvolt 2
Xiao Wu, better known simply as Xiao, is a rogue QUILL operative and one of the supporting protagonists of Azure Striker Gunvolt 2. Serving as Gunvolt's tech support and weapons dev, Xiao's calm and serious attitude masks a fierce hatred of Eden.
He works closely with Gunvolt, providing support for him as an operator. Prefers to be called just Xiao instead of Xiao Wu.
He worked for a division of QUILL in his own country, but after his unit was suddenly taken over by the invading forces of “Eden”, he fled across the sea to join up with Gunvolt to report the invasion.
He’s a pretty straight-laced, serious guy. He’s usually quite calm and gentle, but because of his deep hatred against Eden for their role in the invasion of his homeland, the subject can reveal a very emotional side of him that is not often seen.
Xiao is a young boy with green eyes and short blue hair with some lighter ends. He wears a green jacket with black and orange highlights with the sleeves rolled up, a black undershirt, pale green shorts, and thigh high black boots with gold highlights.
He wears three pairs of watches, one on his right wrist, and two on the left.
Despite his rather young age, Xiao presents himself in a rather calm, mature and serious manner, always focusing on the task at hand and preferring not to have that focus derailed. However, he isn't a stick in the mud, and is quite easygoing, lightly and somewhat awkwardly reminding Quinn that the commlink isn't for personal chat whenever she does so, never flat out telling her off. He also has a rather dry sense of humor. When Gunvolt finishes his advice not to overheat, Xiao tells him not to steal his bit. However, this persona conceals a deep rooted hate for Eden, as a result of their invasion of his home, which he rarely allows to surface.
It would seem that Xiao is somewhat sly and secretive, never actually revealing who his contacts are and refusing to indulge his own private motives. It is also implied that he isn't as friendly as he appears, not trusting GV with the power of The Muse, instead keeping it for himself. While Xiao normally uses the nickname GV, in the Japanese script of the secret ending he refers to Gunvolt by his full name while speaking with Nori.
Xiao almost originally served as a QUILL operative in his home country of China. However, at some point, his nation was attacked by the multinational Adept union Eden, and QUILL's presence in his country was wiped out. Distraught, Xiao fled to Japan, where he met former QUILL agent Gunvolt after his battle with the Sumeragi Group, and began working with him, using his skills to develop GV's equipment, provided mission support, and using his various contacts to provide information.
Infiltrating the Garden
Xiao somehow manages to get Gunvolt and himself into Tashkent, allowing them to infiltrate Eden's headquarters, the Garden. Soon after, his commlink with GV is cut off due to Zonda's Septima.
Hidden Agendas - Secret End
Contains spoilers for the game's true ending
This ending is only attainable after clearing 80% of the Challenges for BOTH Gunvolt and Copen. Once the condition is met, clear Garden 3 again as either hero. The cutscene plays after the post-epilogue save prompt.
Xiao thanks an unknown person for providing him a way to get into the Garden. The other person replies that it's no problem.
The scene reveals an unspecified alleyway where Xiao is talking with Nori. She hands over a pendant-shaped Glaive to him, one that apparently contains all of the Muse's power after Zonda's defeat and GV's duel with Copen.
Xiao questions why it's a pendant, Nori just replies that it looks cuter that way. Nori then talks about how Xiao had planned for Mytyl and Joule's fusion to awaken the Muse and seal it into a pendant. She asks what he plans to do with the pendant, and the power it contains.
Xiao denies any claims, saying that Mytyl had suffered her entire life due to the Muse, but he cannot leave such a power in the hands of Eden or GV. With the Muse's power safely sealed, he claims Mytyl can lead a normal life now. Nori calls him out on his bluff, asking him his REAL intentions. Xiao merely chuckles, and says he has a surprise he's preparing (though he says "it's not anything bad").
The scene fades to black as the game returns to the title screen.
Xiao Wu appears as a collectible pixel sticker for clearing the "Get Equipped" challenge.
As an adept, Xiao possesses some sort of septimal power. What it is has not been revealed, and it has not been alluded to within the story itself. It may have some combat capability, as Xiao assured GV he would keep Quinn safe when the latter was anxious about the possibility of Teseo targeting her.
Xiao is very skilled at hiding his activities. He is able to feign loyalty to QUILL while working with wanted ex-member Gunvolt, sharing their intelligence with him and even ordering equipment for his use, with no concerns that his subterfuge may be exposed.
Xiao also displays excellent intelligence gathering on his own. Somehow he was able to track down Gunvolt while the rest of QUILL can't. He is also aware of confidential information such as the means to extract an adept's septimosome, the circumstances of Joule's creation, and Nori's true identity.
Actually, he’s a character whose design work began very early but due to several reasons (work on him) was postponed. By the time I resumed working on him, his “setting” had been changed to that of a Feather member and thus I rethought (his design) into a Feather uniform-like look. I had instructions: “must be androgynous!”, so as a notation of that the thigh-high boots I had him wear might look shorts that made him appealing: the female staff members who took part in the meeting also liked it so I settled for that.
- Similar to Zeno, Xiao's septima is never revealed.
- Joule apparently has a habit of mistaking Xiao for a girl.
- Xiao and Nori were working together for an unknown period of time before splitting up after Eden was destroyed.
- According to a staff interview in the Armed Blue: Gunvolt Complete Works, Xiao was once intended as a playable character alongside Copen for ASG2 during early stages of the game's development, when Gunvolt was still intended to be the main antagonist.
- When questioned by Nori about his intentions, Xiao brings up and denies the possibility of him giving Mytyl's glaive to Eden. This may imply he has some past relationship with the group.
