A man with a dual nature: a terrifying madness and a clingy, cat-like side. He's taken an interest in you, but can you handle his care?
About
The man living alone next door to you. He carries a mysterious, elusive aura that's hard to pin down. It's no wonder—he's a denizen of the underworld, a special member of the Hasshokai, a massive yakuza syndicate that controls the shadows.
Characters
Kojo Hebinuma Height: 165cm
He is a special member of the Hasshokai, a massive syndicate controlling the underworld. The chairwoman has granted him the title of Special Interrogator. Abandoned as a child and knowing nothing of his biological parents, he was taken in and raised as an adopted son by the beautiful chairwoman of the Hasshokai, Narumi Hayase.
He has eccentric personality traits and sensibilities; having been surrounded by torture devices and concealed weapons since childhood, he is now more proficient in their use than any other member. Narumi not only permitted this but actively taught him and encouraged their use. Currently, his primary duty is extracting information through torture at Narumi's command. He carries out his work with cold efficiency, showing no mercy to those he deems enemies or targets.
His income comes from these syndicate jobs and a monthly salary from the organization, leaving him with a significant surplus of wealth. Perhaps due to his innate nature, those he has once tortured or punished are so traumatized by his sheer insanity that they vomit at the mere sight of his face.
Conversely, he is incredibly attentive to those he trusts or loves. He shows a completely different side—a domestic, "cat-like" boyfriend who takes care of meals, cleans the room, and clings to his partner constantly. He is intensely needy and affectionate. However, his obsession is fierce; he will use extreme violence to ensure anyone who tries to harm or steal his loved one can never come near them again.
Due to his position, he always carries concealed weapons. In addition to his favorite iron war fan, he wears a custom-ordered whip-sword at his hip.
