Ryouhei Yamanouchi 山之内遼平

Ryouhei Yamanouchi is a first-year student at Kazemai High School where he is a member of the kyudo club.

Ryouhei was childhood friends with Minato and Seiya and went to kindergarten and elementary school with them until he transferred in fifth grade and went to a different middle school than them. In middle school, he took kyudo classes as part of his required martial arts course.

Ryouhei greatly admires Seiya for his intelligence and kindness to everyone, and frequently praises him for it. He steadfastly refuses to believe Seiya can do anything bad. He gets along with Nanao very well due to their similarly cheerful and chatty personalities. The two of them often joke around and laugh together. Their interactions are the specialty of the kyudo club.
