Background
Aki Hayakawa was born and raised in Hokkaido, Japan, an island with a low population density, famous for its natural landscapes such as volcanoes and Hot Springs. He lived a simple and quiet life in a small town until a tragedy changed his life. As a child, his family, including his younger brother, Taiyo, were killed by a weapon Demon Attack. This loss becomes the main trigger for his revenge against the Demons, prompting him to leave the peaceful rural life and join the Public Security Bureau as a demon hunter in the big city.
This childhood Trauma leaves Aki living with the ultimate goal: to kill the weapon Demon to avenge her family. However, this journey led him not only to the fight against the devil, but also to emotional suffering, betrayal and sacrifice.
