After catching Haruto with his arms around Oto, Tenma's rage can't be doused. He challenges Haruto to a battle to force him to give up his love. Unfortunately for Haruto, the battle is the Manly Man Festival in Kyoto—a three-sport martial arts competition in which Tenma, as a former junior champion, clearly has an obvious advantage! Haruto's only got two weeks to train before his love life may be extinguished forever!
