SOLITUDE
Daijirō Kutsuwa arrives to Kaimei High School as a substitute teacher for Kiri's class. Shortly after class, he tries to peep under Himeko's skirt, remarking that Himeko's skirt was too short. He then threatens her to dye her hair black by threatening to reveal her Onihime past to everyone in school. However, Kiri witnesses the threat and later abducts Daijirō and forces Daijirō to apologize for what he had done to Kihara while broadcasting the incident live for all the school to witness. After Bossun and Tsubaki arrived to talk some sense to Kiri, Kiri let Daijirō go. Despite this, Daijirō demands Kiri to apologize, or he will have Kiri expelled. When Daijirō trash talks Himeko and the others, Bossun smacks him down.
