"'I want to live.' - Akiyuki Takehara"Takehara Akiyuki (竹原 アキユキ Takehara Akiyuki) is the main male protagonist of the series.

Personality
Akiyuki is an enthusiastic high school student who lives on Sentan Island. He can be described as a caring and charismatic person, oftentimes willing to help others.

Biography
Akiyuki's life takes a dramatic turn when a Haruko bomber from the religious cult of Ruikonism causes him to transform into a Xam'd. Immediately following Akiyuki's transformation, the Northern Government attacks Sentan Island, releasing humanfrom weapons. After he manages to save his close friend, Haru Nishimura, and defeat one of the humanforms, Akiyuki is subdued by a mysterious woman named Nakiami. She takes him back to the postal airship, the Zanbani, where she begins to help him learn how to coexist with the being within him.

Powers and Abilities
After being implanted with a Hiruko by a suicide bomber, he gained the ability to be turned into a Xam'd. His Xam'd appearance is a white humanoid creature with orange stripes, green knee pad-like shells that cover his knees, and a head that resembles a goldfish.

Following abilities that he gained as Xam'd: In spite of his remarkably immense powers, he still has weakness where his experience with Xam'd power and relationship with Hiruko are concerned. If he stays in his full Xam'd form or partially transformed for too long, he would either begin turning to stone, or suffer amnesia where his face would be masked. Even though his relationship with his Hiruko eventually improved, it was still not enough to prevent him from suffering amnesia in the prolonged transformations.
 * Superhuman Strength: As a fully transformed Xam'd, his natural strength is amplified several times, and even enables him to jump large distances. While partially transformed, his strength is also amplified, but not as much as in his full Xam'd form.
 * Biological Explosion: Akiyuki appeared to possess this, though it only works against Humanforms. He can perform this by channeling electrical impulses to his Xam'd foe's body through his fists, which makes them inflate and explode.
 * Blade: Whether in full Xam'd form or partially transformed, he can transform his right hand into a large blade that can cut through flesh at ease and even cut up a Humanform.
 * Tendril Attack: Akiyuki can turn his fingers into long tendrils with unspecified maximum length that can ensnare and possibly cut through a Humanform's body.
 * Shield: He can manipulate his Xam'd mass into a powerful round shield that can deflect a Humanform's spore beam attack.
 * Spore Wings: After he remembered his identity thanks to his second reunion with Haru, he gained a new Xam'd power to manifest ethereal, insectoid wings that enable him to levitate in the air.
 * Transference: In battle with the Black Xam'd Emperor, Akiyuki meets the masked emperor on the spiritual plain while their Xam'ds do battle. As they talk, it becomes plain that the emperor isn't truly evil, but just wishes to live. So Akiyuki displays his final Xam'd ability, the transference of his being to the Xam'd Emperor, giving the emperor everything. When he does this, the emperor gains the memories of Akiyuki, and Akiyuki's name, while Akiyuki becomes a masked wanderer, and his Xam'd form is turned to stone.
