The initiator of the group

As a child, Kyosuke took Rin, Mahito, Kengo, and others along, and brought Riki, who had lost his parents, into the group. He is not in the same grade as his peers and still takes on the role of organizing and setting goals within the group.

Tasks related to baseball

He can turn ordinary small tasks into tasks completed together by his partners. The proposal to form a baseball team continues this approach: everyone needs to find members, practice, and collaborate to reconnect the gradually dispersed campus life.

The daily life of a leader

Although sometimes mysterious, Kyosuke also enjoys reading shonen manga and has a laid-back and playful side. Riki's trust in him comes from living together for a long time, and Rin's social awkwardness is also related to being cared for by her older brother since childhood.
