Кікьо Ріо

A first-year political economy university student. He is the keyboardist for the band Argonavis. Since childhood he excelled at everything, from academics to sports and music, was called a "child prodigy". He hoped to be a baseball player in the future, but right before he was able to participate in the Japanese national high school baseball tournament, he was injured and he abandoned that path. Although he doesn't reveal his emotions, seems apathetic to people, and doesn't get close to anyone, he responded easily to Yuuto Goryou's scout. Since joining, he has been giving his all.
