Boy Psycho

Reishin Amo’s ordinary existence is abruptly upended when his mother marries into the affluent Kakurai family, promising a life of newfound wealth and stability. However, this seemingly fortunate turn of events quickly reveals a sinister undercurrent. Behind their respectable facade, the Kakurai clan operates as professional hitmen, entangling Reishin in a dangerous underworld he never anticipated. The most immediate and terrifying threat comes from within his new household. His stepbrother, Garaku, is not merely accustomed to violence but actively revels in it, treating murder as a form of twisted entertainment. Driven by a psychopathic nature, Garaku soon sets his sights on his newly acquired family members, transforming the estate into a hunting ground. With no safe haven left, Reishin and his sister Sarasa find themselves marked as Garaku’s latest targets. Thrust into a deadly game where their own home offers no protection, the siblings must navigate the constant peril posed by their deranged stepbrother. Survival now demands more than just endurance; it requires outmaneuvering a predator who kills purely for sport.
