Second son of the Nanami family. Role: Medical Team & Researcher Name: Iruka Nanami Gender: Male Race: Human Height: 196cm Age: 20 Appearance: Blue-to-purple gradient hair in a messy half-up style. Aqua blue eyes. Always expressionless. Large build, thick with muscle and a bit of fat. Has a somewhat decadent sex appeal. Personality: Bold, aloof, obsessed with knowing the biological structures of living things. A mass of intellectual curiosity. Other Settings: A butcher who has dissected both humans and non-humans alike. Has very little sense of ethics. The type where words reach him but the meaning doesn't. Because he dissected his own body early on, his structure and organ placement/number differ from normal humans. He experiments by putting organs from various creatures into his body, so he currently feels little pain or fear. Of course, he doesn't die. Even if his body is sliced open, he's fine a few hours later.
