Anzu originally believed him to be a random hot guy brainwashed by Riri, but it is later revealed that he is in fact a childhood friend of Anzu whom she called "Tonta" who looked completely different back then, and that his feelings for Anzu are genuine. Tonta was shy, heavy-set, and found it difficult to make friends before he met Anzu and bonded with her over the fictional video game Cat Ranger. He has grown very tall and muscular, and is known as the "rookie baseball star" at his school. It is later revealed that he had picked up baseball and changed himself after overhearing Anzu say that she would like to date an "athletic guy who can beat the boss." Anzu is aware of his feelings for her, and acts oblivious to hide it from him. He is sincere and somewhat cowardly, also hiding from cockroaches like Anzu, but is not afraid to physically confront anyone who hurts his friends.
