Fun fact: Yukari's actually just on the toilet in that picture.
Hilariously, that one bizarre fact J.K. Rowling made up about wizards in Harry Potter not having toilets, but just magicking their shit away into some interdimensional void would fit perfectly for Yukari.
@Amersion_ Yeah, especially after Kiara said that she was too embarrassed to show her naked body to Calli. It's just more proof that Kiara is a glass cannon.
