A first-year student at Date Tech High School, S. His jersey number is 7.

A tall setter who participated from the first preliminary round of the Spring High. Although his skills are still raw, he plays using his height, comparable to Aone. According to Mōniba's explanation, his nickname has changed from "New Weapon Large Setter" to "Developing Setter" to "New Iron Wall," indicating he is a player of great potential. Kamisaki mentioned that "his movements are still amateurish," and Futakuchi commented that "he is too serious, always going full throttle, which often means he can't put on the brakes." In the quarterfinals of the Spring High preliminaries, he was defeated by Iwaizumi (Aoba Johsai) who broke through his block head-on.

A member of the prefectural first-year select training camp. Initially opposed to Kunimi's (Aoba Johsai) playing style at the same camp, but after interacting with Hinata, he began to pay close attention to Kunimi's play. Also, he is interested in Hinata, who is recognized by Aone.

After graduating from high school, he joined an automobile manufacturer and, like Tsukishima, plays for the V.League Division 2 team, Sendai Frogs.
