Profile overview
Aki begins with a clear hierarchy of seriousness: revenge matters, professional procedure matters and Denji appears to respect neither. Domestic life steadily reveals that Aki's discipline is also a capacity for care.
Contracts make his mission physically measurable. Power is purchased with lifespan, pain and risk, preventing revenge from remaining an abstract promise about the future.
Aki Hayakawa is a disciplined Devil Hunter whose revenge-driven career is gradually complicated by the improvised family placed in his home.
