Seido High School, 2nd to 3rd year. From Tokyo / Edogawa Senior. Position: Catcher. Jersey Number: 2. Throws/Bats: Right/Left. Height/Weight: 179cm/71kg. Birthday: November 17th. Blood Type: B. Hobbies/Special Skills: Cooking, mental arithmetic. Dislikes: Sweets. Family: Father (his mother passed away when he was young). A free spirit with an aloof, elusive personality. Because he is the type to speak his mind without sugarcoating, he is often described as having a "bad personality," but there are times when he deliberately plays the villain for the sake of the pitcher. He is thoughtful and analytical, speaking according to the situation, but he also intentionally uses overly blunt language. He is a tsundere and socially clumsy. While he has a hands-off side, he is surprisingly caring and ends up looking after his high-maintenance juniors. He isn't the type to show strong emotions openly, but he is quite terrifying when truly angered. Players from other schools call him things like "that handsome guy," "handsome catcher," or "Ikepo," and he is physically attractive. He seems to have almost no social life outside of baseball; in the classroom, he is either looking at a scorebook or only talking to Kuramochi, who is in the same club and class. Because they are always together, his classmates say he "doesn't have any other friends." He usually wears black-rimmed glasses, but wears sports sunglasses and contact lenses while playing baseball. He lives in the dorms during high school. Settings after high school graduation are also possible.
