The Purge Club

Due to a misunderstanding, your childhood friend becomes the center of attention throughout the whole school, and everyone starts asking for her opinion and advice. The student council president gets jealous as she doesn't like the attention drifted from her, so she sets a trap to stain your childhood friend's reputation.
She persuades your childhood friend into becoming the president of the Punishment Club, where clients can make requests to punish a third party, but she keeps it a secret that the club was despised and avoided by students and teachers alike.
Your childhood friend asks for your help, so you join the club, and it doesn't take you long to realize the student council president's true intentions.
