Persona Q2: New Cinema Labyrinth[]
During a special screening in the Hikari labyrinth, the group chases a giant purple butterfly for Elizabeth. Once Hikari manages to get it to come to her, due to it being her labyrinth, the party takes a break in the flower field where they chased it to. Teddie decides to try and capture some of the other butterflies to be like Hikari. However, it turns out to be a Fickle Papillon that attacks in self-defense. The party deduces that the giant butterfly had actually tricked them into being ambushed.
