The classmate guys ask Souta to find a mysterious girl in a white dress. Souta discovers the girl is Megumu, but uses Mimori as a decoy, and learns of her back story. With the help of Ruri, Souta and Mei visit the alternate world where dorm advisor Miyuki is a student there who bears his last name and a main character flag. When they return, Souta's death flag becomes large. After Mei tries to break it, Sakura wipes Mei of the knowledge of the flags. For summer break, Souta is taken to Akane's mansion, where some of the Quest Dorm residents gather, but he gets stuck in the girls outdoor bath.
