Daisuke, Kyoko, Rin, Kuro and Mimi travel to Daisuke's hometown where they meet his family, including his younger sister, Chika. As the girls go to the beach, Rin recalls the times she went to the beach with Aki and Reiji. Later that night, Rin tries to make a move on Daisuke as he sleeps, but backs off when she believes him to be 'a bit too big' for her. Meanwhile, Kyoko, who got very drunk, mistakes Chika for Daisuke and kisses her, though forgets about it the next morning. The next day, the girls help with preparations for Obon, giving Rin fond memories of her mother, so Daisuke lets her hug her during the night. They return home the next day, with Rin leaving behind a photo of them to sit next to a picture of Daisuke when he was younger.
