Naoyuki Andou

Naoyuki Andou shares a bond with Shishigami Kou that stretches back to their earliest childhood — a connection that makes his eventual break from him all the more painful. When Kou awakens to a powerful mechanical ability and begins using it to slaughter innocent people, Naoyuki finds himself unable to stand by and watch. Refusing to condone the violence, he severs their friendship and turns to Inugami Ichiro, a young man who wields a similar power. Drawing on his extensive knowledge of technology and science fiction, Naoyuki steps into the role of technical mentor, guiding Inugami in understanding and controlling his extraordinary body — all in pursuit of putting an end to Kou's rampage.
