Ping Pong THE ANIMATION

Tsukimoto Makoto (nicknamed Smile) is a quiet high-schooler who's been friends with the loud and energetic Hoshino Yukata (nicknamed Peko). They're both in the table tennis club and are very good at it, though Smile's personality prevents him from winning against Peko. The club teacher however notices Smile's talent and tries to make him gain some sportive tenacity.
