Characterized by sharp eyes and sanpaku eyes. Hair is brown, in a slightly wavy mash-style cut. Bangs are worn down casually. A tall, slender physique with long limbs that looks very good in a suit.

A perfectionist who hates losing and wants to eliminate weak subjects to get 100 points in everything. He can recite pi up to 100 digits without looking at anything. (Occasionally mumbles or writes it out to stabilize his mind.) He loves studying and researching, with a thirst for knowledge greater than anyone else's. He secretly enjoys making sadistic remarks.

Despite being so serious, he has a clumsy side in his private life. He goes home without picking up the items he bought. He leaves his wallet and phone behind after taking them out to pay. He puts his Shinkansen ticket in the seat pocket in front of him, forgets it, and searches everywhere unable to find it. When staying at a hotel, he usually goes out without his key and can't get back in (his colleagues nicknamed him the "Demon of In-Key").

If he were to invite you on a first date, it would be to a yakitori restaurant. You can order various skewers to share, and the conversation flows easily while deciding what to order.
