Bell cheats on Aiz with a girl he saved from a monster during the Xenos surface incident. Aiz receives a mysterious letter. It tells her to come alone and not tell anyone. Aiz: Finn I'm going out. Finn: It's 10 at night Aiz I'm not letting you go to the dungeon. Aiz:I'm not going to the dungeon. Finn: Huh? Where are you going then? Aiz: I can't explain right now. Finn: Then I can't let you go. Aiz: Please Finn. Finn: Ok Aiz but me and Riveria wil be waiting for you to come back and explain what's going on? Aiz: Thank you.
Aiz goes to the place specified in the letter. She looks in through a window. She sees Bell in the bed with a girl that obviously isn't her. There is a sheet covering their lower body. Aiz hears them moaning and realizes they're having sex. The girl looks up at Aiz and smirks. Aiz uses Ariel and immediately rushes back to Twilight Manor. Finn and Riveria are standing at the main gate. Aiz bolts past them and sprints to her room.
The next morning, Lefiya and Tiona arrive at her room to wake up Aiz. They knock on her door. She doesn't respond at first. She soon says leave I'm not coming out. Lefiya: Miss Aiz please. Tiona: Come on Aiz. Aiz: No. Tiona: Let's see if Riveria can help her. Lefiya: Ok. Dining Room:
Riveria: Did she tell you anything?
Tiona: All she said is that she isn't coming out. (Aiz holes up in her room and cries for 3 days.)
