NocturnaL

Episode 1 - 2 part 1 - _Nocturnal_ Sayoko Miyamura is an honor student, friendly and popular with her classmates. She is like a flower on a high peak that Etou has a secret crush on. While hanging out at night, Etou sees Sayoko Miyamura in a dispute with some guys. Etou was about to pass by, feigning indifference, but then he decided to intervene. The two hold hands and run away from the place. The impression he gets is somehow different from the one he saw at school during the daytime. Sayoko Miyamura, not her... she had a dual personality. Her personality "Yako" was created for Sayoko to be a good girl. She appears at night and is the complete opposite. She's rebellious, foul-mouthed, and sexually unrestrained. Episode 2 part 2 - _François_ A "teacher'' who quit his job as a teacher is assigned to educate Yumeko Origasa, who has stopped attending school. During his time as a teacher, he was attracted to Yumeko's high-handedness, her strangely mature sex appeal, and the way she always looked out the window, not fitting in with her surroundings. However, when he could no longer control his own perverted sexuality, the "teacher" was driven by remorse and resigned from his position. He becomes an obedient dog to Yumeko, who plays with his twisted sexuality, and vows to obey her. (Source: Mediabank, translated)
