When Aoi returns home from school with injuries, she receives first-aid treatment from Ittōsai. As he bandages her body, he learns about what had happened to her, becoming displeased when he learns that she refused to fight back, even though the ones who attacked her are former allies. Sometime later, several of the Red Tail girls arrive at the Kunieda residence while Ittōsai is still bandaging Aoi. He explains what Aoi had apparently told him and comments that she might listen to their reasoning instead. When he finishes up, he notices that some of the girls' male classmates have arrived, particularly Oga.[1]
