Summary
Elaia is in her room looking at the new book Lindy has given her; THIRTEEN EVIL GIRLS. However, a strange power surrounds her and her hair turns brown like mud, and her shirt turns green. Not only this, but her skirt also turns brown like her hair! Suddenly, not only is her hair brown, but she has blue tips, which are barely noticeable. So, she runs to Emmy's house to ask for her help, and undoes her spell, where the magic on Elaia is broken. Emmy tells her that it was because she had been affected by an Essi, but that's okay, she wasn't going to die, and finally, Elaia finishes the book and thanks Lindy.
