Exasperated that Tohru is still using her school swimsuit at the pool, Arisa and Saki decide to buy a new swimsuit for her. Yuki and Kyo are forced to come along but their input was made moot when the girls decided to get a pink swimsuit. While having soba for lunch, Arisa recalls how she first met Tohru in middle school. Back when she was still in a violent street gang, her idol was the Crimson Butterfly who had since become a mother and had a daughter who goes to the same school as Arisa. However she was shocked that the Butterfly's daughter turned out to be a plain, strange, spaced out girl, and Kyoko (the Crimson Butterfly) became a doting parent. It is at their home that Tohru first calls Arisa "Uo-chan" after Kyoko first suggested it. The love displayed between Tohru and Kyoko leads Arisa to be reminded of the neglect from her single father, and she rejected them both. The meeting and her past circumstances causes Arisa to break down as she realizes that she may become permanently stuck in her situation. In a post-credits scene, a group of female delinquents try to intimidate a passerby, but run away when Momiji begins speaking German to them. (Source: Wikipedia)
