Ep. 3: Koushi Navigates Sisterly Chaos and Returns to Middle School Life

3

The girls vie to prove their superiority as big sisters, with Frey cross-dressing Koushi, Mineru testing a formula, Kirya using erotic wrestling moves, and Atena suffering nosebleeds. Serene is too hungry to participate. Koushi accepts this dynamic as sisterhood. Mineru and Frey enroll him in middle school. On his first day, Koushi encounters Sutea Koroya, a friend from before his house burned down. Sutea feigns anger but was secretly worried, recalling how Koushi cooled his hands with ice to hold hers due to her heat intolerance. After hearing about the Goddess dorm, she insists on meeting the girls. Koushi accidentally falls on her, and she punishes him for a potential lewd incident after overheating. He hopes to prove the dorm is normal, but they find Frey in a bunny girl costume and Mineru in only a lab coat and panties due to a chemical explosion.
