Megumi brings the rest of the class to Masamune's home in an attempt and get Sagiri to go back to school, but Masamune refuses. Later on, Masamune learns that Elf lives next door after he hears Sagiri's complaints about piano sounds coming from next door. Masamune visits Elf's home where he learns that she is a well-received author, and is curious to learn more about how she works. They become great friends, but also great rivals, and decide to have a contest to decide who gets to partner with Eromanga Sensei for their next novel. Later on, Sagiri accuses Masamune of lying about his relationship with Elf and orders him to leave her room for the remainder of the day.
