Kazuma Torisuna

Kazuma is the main character of S-CRY-ed and a Native Alter User.

Personality
Kazuma is thought to not think before he acts, but this would prove to be false. He does think, but rather quickly. He is headstrong, a trait that causes he and Ryuho to be bitter rivals.

Synopsis
He'd never met anyone so skilled with Alter as Ryuho, and Kazuma's soundly trounced. However, even as he's confined at HOLY's facility, he refuses to admit defeat. Eventually, with help from Mimori, he actually manages to escape back to the outside. As he learns of HOLD and HOLY and their underhanded tactics, Kazuma begins to focus his attention on them. After the thrashing he got from Ryuho, seeing their darker side just makes him that much angrier. He yearns to tear HOLD apart for trying to ruin people's lives. And if he can pay Ryuho back for their first encounter, all the better.

But with a sense that he isn't yet strong enough, Kazuma does what he does best: pick an option, charge headlong, and don't let anything stand in the way. So he heads for the Alter Forest, full of wild animal Alter Users. There, Kazuma comes face to face with a peculiar Alter, one Ryuho had once told him about. In the course of the battle, he manages to rip a piece off the Alter, and this evolves his own Alter, making it much more powerful.

When he fights Ryuho the third time, this time with the Shell Bullet, the sheer force of their fight rips open a door to the "other side" and throws them into it briefly. In the aftermath of the Second Uprising that he and Ryuho unleash, Kazuma spends the next eight months fighting in an arena, fighting without a reason. After an encounter with Mimori and Asuka Tachibani, however, he begins to pick himself back up and starts looking for Kanami, ultimately finding her and Ryuho again at the same time, just before Kanami is kidnapped.

Alter
Shell Bullet: an alloy-type Alter which transforms his right arm into a weapon. At its first level, Shell Bullet covers Kazuma's right arm with protective metal armor and creates three curved fins of metal jutting out from his right shoulder blade, each progressively larger as they near his shoulder.. The fins break apart to propel Kazuma forward at great speed, increasing the power of his strikes, which Kazuma labels as Bullets.
 * Shell Bullet Ultimate in his second form, Kazuma's arm is completely replaced by a stronger armored arm, four fins of metal jut out of his face near his right eye, and a propeller replaces the three fins on his back. This propeller grants Kazuma flight, as well as eliminating the firing limit imposed by his first form. On his fist is a small aperture which can absorb additional Alter power, further strengthening his attacks
 * Proud Fist: in his final form, Kazuma's Alter covers his entire body, causing him to appear as a humanoid cross between a samurai and a lion. His Alter-absorbing fists grow even larger, and his propeller becomes a whip which serves much the same purpose as the fins from the first form or the propeller in the second form.
