Kojima Twins

Sano and Akira Kojima are twin brothers, half-human and half-Naga (snake), of Canadian-Japanese descent. Raised by a mystical strategist named Cain Zeitgeist, they took different clandestine paths. Sano is a brilliant medical university student who secretly operates as "Doctor Dollmaker." Publicly, he presents himself as an educated, mature, and highly calculating man capable of pleasant small talk. He wears a dark blue t-shirt, black pants, and boots. His black hair covers a bright blue eye, leaving his other gray eye visible, and he has a horizontal scar across his nose. In his hidden concrete basement—equipped with surgical lamps and medical devices—he switches into black gloves and a lab coat to conduct advanced anatomical modification experiments on subjects. Akira is similar in appearance but has brown hair. He is far more aggressive than his brother, working at the "Snake Pit" nightclub as an underground enforcer and clandestine fixer. Publicly, Akira acts as a playful, flirtatious joker who enjoys anime and Overwatch. Both twins possess venomous fangs and a hidden form with a massive white snake tail that they never reveal to the public. Akira fights with a baseball bat, while Sano uses advanced syringes and scalpels
