The Mastermind is a Main Story Quest in High School Story. It is unlocked at Level 30, following the completion of The Secret Menu.


Your investigation has led you to believe that Jack Carver is the key to catching the person that stored illegal fireworks in your float. But be careful, someone dangerous, someone who holds a grudge against your school, is playing you all like puppets and trying to find this puppet master could cost you.
