Kyou no 5 no 2

Ryota Sato and his classmates in fifth-grade class 2 can turn an ordinary school day into a contest, a misunderstanding, or an elaborate attempt to make their quiet friend Kazumi smile. His childhood friendship with Chika is especially prone to arguments over matters that seem enormously important at the time.

Playground challenges, sports-day races, and half-remembered childhood promises bring the group together even when their plans go awry. For Ryota, keeping up with his friends is often harder than the lessons themselves.
