15화: 이바리에 대한 야쿠자의 충성 때문에 세이지가 하나코의 사랑을 거절한다

15

Seiji receives his very first love letter but is worried his job as a yakuza would make him an unsuitable husband. Seiji leaves to meet the girl who turns out to be Hanako, Kaori's friend who developed a crush on Seiji after seeing his naked victory dance at the beach. Hibari catches Kousaku spying on them and drags him away for a date. Seiji later tells Kousaku he turned Hanako down because Ibari took him in as a child and if he got married he would have to leave the yakuza. Kaori convinces Hanako that Seiji dumped her because of Hibari. Hanako sneaks into the Oozora house to beat up Hibari but accidentally attacks Ibari so Seiji beats her up, only realising it is her when he takes her mask off. He explains that he does not love Hibari, but his loyalty to Ibari means they cannot be together. He gives her a necklace as a memento of their love. Suzume reveals she called the police to report Hanako as a burglar, panicking all the criminal yakuza in the house; however the police arrest Kaori and her other friends while Seiji manages to sneak Hanako out safely.
