Five ping pong prodigies learn to navigate the harsh climate of competitive sport and the even more frightening realm of self realization.

Makoto Tsukimoto (nicknamed Smile) is a quiet high-schooler who's been friends with the loud and energetic Yukata Hoshino (nicknamed Peco) since childhood. They're both in the local table tennis club and both have a natural talent for it, although Smile's personality always enables him from winning against Peco. The club teacher, however, notices Smile's talent and tries to make him gain some sportive tenacity.—Crunchyroll

Despite being polar opposites, Makoto "Smile" Tsukimoto and Yutaka "Peco" Hoshino have been best friends since childhood. Although the overly confident Peco strives to be the best ping-pong player in the world, he often skips practice, earning the ire of his fellow teammates on the Katase High School ping-pong team. Meanwhile, Smile-in spite of his innate talent for the sport-cannot help but hold back his full strength when playing against others. Through their mutual love for ping-pong, the two have developed a bond that is seemingly unbreakable. When Peco hears that an ex-national team player from China is coming to Japan, he drags Smile over to rival Tsujido High School to observe them. The subsequent trip leads to a clash between Peco and Kong Wenge, who overwhelmingly defeats the former in one game. Stunned by such a comprehensive loss, Peco finds himself questioning why he plays to begin with. Seeing his potential as a player, Katase's coach begins to train Smile to overcome his hesitation, but he is reluctant to play if it is not for enjoyment. As the two struggle to find meaning in the sport, a plethora of stronger players-each with their own internal strifes-await them at the inter-high tournament, where only the very best can persevere. But when these young athletes let their unbridled ambition go unchecked, the hardships they face paint a somber reality as they pursue glory.—MAL Rewrite
