Cencoroll

Yuki notices that her quiet classmate Tetsu Amamiya is secretly caring for Cenco, a strange white creature able to reshape its body into almost anything. Her curiosity pulls her into Tetsu's hidden world just as another boy, Shuu, arrives with a monstrous creature of his own and forces Cenco into battle.

Unlike Tetsu, Yuki has no special creature or power to protect her, yet she refuses to stay out of the conflict. As Cenco changes form under pressure and the fight spreads through the city, Yuki becomes far more important to both sides than either boy expected.
