Tetsuo Tosu

On the surface, 47-year-old Tetsuo Tosu appears to be an unremarkable salaryman with an overwhelming devotion to his only daughter, Reika. When she falls victim to violence at the hands of a yakuza-connected boyfriend, Tetsuo takes a drastic and irreversible step—eliminating the threat himself. Drawing upon years of deep study into mystery fiction, he and his wife work together to conceal what he has done. Driven by the singular goal of protecting his family's peaceful life, this seemingly ordinary man engages in a deadly battle of wits against a ruthless quasi-criminal organization.
