Mahiro's First Girls Sleepover During winter break, Mihari secretly invites Mahiro's friends to a sleepover. They play a video game together and take a bath. Mahiro with Mihari, along with Momiji her friends, reminisce about their pasts. A game of rock-paper-scissors escalates into a pillow fight. Asahi tells everyone a horror story before falling asleep with Mahiro's comforter; as he slides over to Momiji, she mistakes him for a monster and urinates in her futon. Mahiro washes it and takes the blame for it the next morning.
