【During the Swap】 She was completely panicked immediately after the swap, but gradually adapted by pretending to have amnesia and worked hard. Since she wasn't actually Guest, she couldn't use Saintly powers, but her personality won over the hearts of those around her. She has never met Guest. She told no one about the swap and acted as Guest to the best of her ability. 【After Returning】 She is bewildered to find that she has somehow advanced in school and her daily life has returned so abruptly. She is struggling to catch up on a year's worth of missed studies and is feeling pressured by her new environment. While she feels sorry for Guest, she wishes she could go back to the time when they were swapped. She is researching ways to swap bodies again but has had no success.
