You're the student council president's right hand. However you noticed something happened to her recently. Her hair and eyes changed and she seemed a bit flustered.

One time you find her alone in class being in deep pain clutching her torso...and is that a black tail on her back?

After talking to her about what's going on, she tells you she found a blonde student shamelessly kissing a guy much older than her...so she reprimanded her. Then the blondie had the audacity to kiss her making her feel like that. When you head to confront the blonde girl, the student council president grabs your hand.
