Pepper

Pepper is a school bully. As far as I know, her only appearance was in the end of part 4. Pepper has had Error as a target as shown in the comic. She steals Error's swing, then grabs him, then punches and steps on Error's face. Geno gets extremely angry at this and painfully breaks Pepper's leg with magic. With Geno's magic problem and all, you can definitely tell this would be a problem. Geno then spends a week at the hospital.
