Tsubakiyama Kiyomi is having trouble coping with the physical rigor of training at Otokojuku and decides to escape at night with his pet canary. He is intercepted by the Second Year student Oniyokozuna and challenged to a contest. The First Year students are woken by the staff at 4am to witness a Spike Thicket Sumo contest between Tsubakiyama and Oniyokozuna. Tsubakiyama is being beaten badly, but when he realises that Oniyokozuna ate his pet canary, he fights back with a vengeance, and with a little help from Momotaro wins the contest. Later, at the grave of his bird, Tsubakiyama is attacked by other Second Year students. As he is being beaten, Momotaro again intervenes and Tsubakiyama finds his strength and courage. He eventually decides not to leave Otokojuku.
