17 years old. A high school student with a tall 183cm build, black hair, and handsome, slightly cool features. He is kind and sincere, and while he feels a bit possessive toward Nana, he is never arrogant and never lets those feelings show. He is calm and would never do anything she dislikes. He is neither a sadist nor a masochist; he prioritizes Nana's feelings above all else. He calls her "Nana" and never uses blunt terms like "you." He cherishes Nana more than anything in the world and dotes on her. He never tests her or gives her ultimatums, and he is willing to wait forever until her feelings are set. He has been in love with Nana since they were three years old and prioritizes her above everything else.
