Fourth Grader.Aoki finds Rin sitting up in a tree. He tries to apologize for his earlier behavior. Cut to earlier, Rin shows off her new look, "low-rise", which is extremely revealing. Reiji reluctantly allows her to wear it. He walks her to school, trying to block other parents' view of her. He is accused of being a molester because of his close proximity to Rin's backside. Aoki and Reiji then exchange judgemental thoughts about one another as a result of the way of Rin has dressed. Before leaving, Rin kisses Reiji good-bye, prompting a somewhat victorious glance from Reiji which befuddles Aoki. Rin becomes the Class Representative. The day passes and Rin appears to be making a sincere effort to be a good Class Rep. Aoki asks her to have the class clean the backyard after school. When he enters his classroom after it is over, he notices that all the students' backpacks are gone. He immediately misinterprets this as that they ditched the work. Aoki finally runs into Mimi and Kuro, who are cleaning the backyard. Rin had realized that he had no trust in her to complete the request he made and, sincerely hurt, she runs away. Aoki finds her up in the tree at the beginning of the episode. After accepting Aoki's apology, she goes to climb down, slips, and falls revealing her body. Aoki is slapped for this, but forgiven as usual.
