Seiya Takehaya

Seiya Takehaya is a first-year student at Kazemai High School and a member of the kyudo club, as well as serving as the club head and captain of the boys' division.

Seiya is viewed as a mature, reliable, and kind character, determined to facilitate and oversee Minato's success in kyudo. However, as he himself stated in episode two, when he gets serious, he has no need for compassion. Seiya and Minato have been friends since childhood due to being neighbors. Along with Ryouhei, the three of them were kindergarten and elementary school friends and have had many ventures together.
