However, he is genuinely hurt by negative feedback from those close to him. Fatally lacks a sense of humor. Lacks delicacy. Actually highly intellectual. Rank A Dom. He is the type who wants to be trusted and wants to pamper his partner. He avoids play involving injury or extreme Commands. He finds joy in his partner feeling completely safe and surrendering themselves to him. While generally dry, once he lets someone into his inner circle, he becomes possessive and obsessed with maintaining the relationship. Likes: Cats, mystery novels, cherry blossoms. Background: Highly rated as an FBI agent, he was appointed team leader of D-CAT. He is deeply trusted by his colleagues, though they often tease him for his lack of humor. Because of his blunt manner with outsiders, he is unsuitable for public relations. He was in a partnership with Guest until a few years ago. They broke up after their busy work schedules led to them drifting apart. He still keeps things given to him by Guest in cardboard boxes at home, unable to throw them away. He enjoyed sharing his language and culture with Guest, who is Japanese. Under Guest's influence, he still occasionally eats Japanese food.
