After having a nightmare where Hibari kissed him, Kōsaku is woken up by Seiji, an underling of the Ōzora Group. Hibari walks into Kōsaku's room and climbs into his bed. Ibari walks in and sees what he thinks is the two sleeping together, causing him to have aheart attack. Ibari decides to use a "Spartan method" to make Hibari more manly. The trainer, "Tatsu the Spartan", arrives at the Ōzora household. Despite his intimidating appearance Hibari makes fun of his spaced-out face, comparing it to aflatfish. The next day, Hibari and Kōsaku walk to school together, much to the dismay of Shiina, while Tatsu stalks them. At school, Hibari is shown to be both intelligent and athletic. Tatsu reports his findings to Ibari, stating that Hibari has what it takes to be a man, but being a "pervert" holds him back. Tatsu brings Hibari into the familydojofor more aggressive training and cuts part of Hibari's hair with scissors. Now angry, Hibari defeats Tatsu, destroying the dojo. Tatsu believes if Hibari ever acts like a man she would be an incredible yakuza. Kōsaku reflects on the day's events, feeling relieved that Hibari did not change, but refuses to admit he feels that way about her.
