Waka Kirishima

Waka Kirishima is the youngest member of the Kirishima family, who live next door to the Yuzuki household. She shares the same classroom as Gaku, the fourth Yuzuki son, and the two are close friends at school. Her personality stands in stark contrast to her older sister Uta, who is bold and tomboyish — Waka, by comparison, is gentle, soft-spoken, and calm. While her physical abilities are fairly average and she tends to have an airheaded side, she often surprises those around her with a level of thoughtfulness and maturity beyond her years. To Gaku, she is his most cherished and irreplaceable companion in school life.
