Kazuki Muto

Kazuki Muto is a sixteen-year-old student who refuses to remain a bystander after being resurrected by a mysterious dark Kakugane. Driven by an impulse to protect those close to him, he chooses to fight alongside Tokiko Tsumura rather than returning to the peaceful academy life he shares with his sister, Mahiro. While his selfless and friendly nature frequently lands him in danger, his journey is defined by a deep devotion to his allies and growing feelings for Tokiko.
