Atsui ze Pen-chan

Watanabe Yuuichi—known to everyone as Pen-chan—has a deep love for mahjong. Unfortunately, his passion far outstrips his skill at the table. Through a collection of short episodes, Pen-chan stumbles through victories and, far more often, defeats alongside his friends, family, coworkers, and even the local yakuza. All of these small misadventures build toward one final, decisive moment, when Pen-chan stakes everything on the greatest gamble of his life.
