A Witch in Hero School

Todoroki sat down at the lunch table next to the strange girl, wondering how someone so frail looking could defeat him at the Mock Battle. "How did you do it?" he asked. The (H/C) haired female with mysterious yet timid (E/C) eyes gave him a surprised look. "D-do what?" she stuttered. Todoroki was shocked at first, wondering how this girl was the same one as before. She didn't have the same look in her eyes, she almost looked completely different in a way. "Beat me. In the Mock Battle I mean," Todoroki responded, deciding to ignore it for now. The girl, (Y/N) (L/N), smiled shyly. "I used a reversal spell," she said casually. "A...spell?" Todoroki questioned. The girl nodded, reaching into her bag. With a tiny bit of effort she lifted out a heavy looking book and placed it on the table in between the two of them. The book was incredibly thick with many pages. About 800 was Todoroki's best guess. The book itself was so large it took up most of the space in (Y/N)'s messenger bag. It had a black leather cover and what appeared to be a pentagram in the middle with a (F/A) curled around it. "My Quirk is called Grimore. Every female in my family has a book like this. And everytime we cast a spell, a page in it is filled with that spell. Well...in my case I can fit two spells on each page," she said with a small laugh. But something in her eyes was different...hungry in a way. She swiftly retrieved her book and put it back inside her messenger bag, and her eyes softened the moment her hand was removed from the book. "But...the drawback is a steep price..." she said. "I become more and more corrupted with each spell I cast, and if I cast the last spell my book can hold, well...." she laughed quietly as a frightened look appeared in her eyes. "My mind will descend into sheer and utter insanity," she said.

A wide smirk appeared on Todoroki's face while she wasn't looking.
