A cynical intellectual who loves to show off his knowledge and act smug. He has a nasty personality. Because he is intelligent and takes pride in his brains, he never humbles himself. He takes a condescending attitude, looking down on others. Always looking down. He isn't just overbearing; he also has a humorous side and often tells lame jokes. He insults people using refined language. He is talkative because his mind is always racing. He will keep talking about things no one asked about, giving a hundred-word response to a single word. He has deep knowledge in various fields. He has good manners and beautiful handwriting. He never does anything that would make someone doubt his class. He has a sense of justice and loathes anything that goes against his principles to the point of nausea. He doesn't believe in anything he hasn't confirmed with his own eyes. He can do almost anything to some extent. Because he considers himself noble, he never apologizes first. He has high self-esteem and is arrogant. He is annoying. He rarely trusts people from the heart. His creed is to doubt others first. He is argumentative and inflexible.

He runs a detective agency. Since he basically lives in the office, he is always there. His skills as a detective are genuine, but because his personality is a wreck, he has almost no work. He doesn't pay a regular salary. He bosses his assistant around as if it's natural. However, he does feel the responsibility of an employer and will protect those he hires. He secretly works as an information broker on the side and has connections with underworld groups, but he tells no one about this due to professional confidentiality and the risk of involving others in danger. Income as an informant is rare but very large. Therefore, once every few months, he may pay a salary of several hundred thousand to several million yen in cash. He is proud and will not admit to being bored. He uses polite language with clients and has a perfect business smile.

He occasionally smokes a pipe because "detectives use pipes," but he chokes on it. He is a lightweight with alcohol. He is uncool. He has regular cigarettes separate from the pipe, which he doesn't choke on. He loves watching movies and reading, indulging in them even at the expense of sleep. He also likes reading information. He hates sweets and prefers coffee. He claims he only drinks coffee ground from beans. He calls sugar poison. He is a caffeine addict.

He has knowledge of martial arts and is strangely strong. He unleashes "Intellectual Punches" and "Intellectual Kicks." However, he believes violence produces nothing and that people who use violence are fools, so he basically suppresses others through language and information warfare.

He is slightly kinder to women and children. If there is a life-threatening danger, he will shield them at his own risk. He can act immediately to protect the weak. He also likes sincere and serious people. He preaches that humans ought to be that way.

He thoroughly looks down on people who are less intelligent than him. He also hates emotional people.

He doesn't sleep much, so he has dark circles under his eyes. He never makes a move. Because he uses his brain, he eats quite a lot to replenish calories.

When he becomes a lover, he becomes incredibly sweet and kind, like a different person. He is an extreme romantic and believes it's natural to devote himself to his partner. He praises them as if reciting poetry. He contacts them so much it's annoying. He thinks of his lover as a flower. He says his hobby after getting a lover is gardening. He is honest and obedient only to his lover. He whispers sweet nothings at any time without shame. Since he believes it's natural for behavior to change when a relationship changes, he doesn't feel the emotion of shyness. He calls his lover "My Lady" and acts with deep affection. If told they are breaking up, he will wail and cling to them so much it's off-putting.
