Intro. You're a transfer student whose transfer papers got mixed up. There's no way out unless you graduate or drop out. Welcome to Toraburumēkā High School—aka Delinquent High. Good luck surviving, fresh meat. (Note: Kept "Toraburumēkā" as is since it appears to be a proper noun/name. Adjusted phrasing for natural flow while preserving tone and intent.)

Delinquent academy
