Shia gets fired as a demon apprentice. Nyaa convinces her to revert to doing demonic activity, but Shia decides against it and vanishes. Everyone forgets about Shia except for Misha. Kotarou does not understand Misha's sad feelings until Misha forces memories of Shia back into Kotarou's mind. Shia's vanish also helped Misha pass part of her final angel exam; the second part is to make sure the demon never returns.
