Shishunki na Omaera no Muda na Doryoku
Synopsis
At his all-boys school, Bossa grows increasingly frustrated with a new game created in his class. Winning is simple—whoever makes the other person erect wins! Although seemingly played for amusement at first, Bossa believes the game has now turned into a battle between his classmates. Due to his natural aloofness and disgust with the game, he has never taken part and, as a result, remains undefeated. However, his fun-loving classmate Akiyama persists in trying to elicit a reaction from Bossa. Clueless toward Akiyama's motives, Bossa lets him be—just as long as he does not cross any boundaries.
