In a world where the police are not on the side of good, criminals are powerful, and everything is chaotic, a 16-year-old young man named Loyz Unreavel, the son of the famous member of the Golden Horn motorcycle gang, Kefzz Unreavel, inherits his father’s fortune after he is killed in front of his eyes during a shopping mall exit. Tired of seeing so much injustice and evil around him, he decides to become a vigilante and fight against the evil in Japan. One day, perhaps, he hopes to avenge his father, clear his family’s name, and escape from the group known as Firegroll, infamous for killing family leaders with a history tainted by wickedness and blood.
