Your newest mission is to blend into the Ryuho Academy as one of its students and take out the headmaster. Doesn’t sound too difficult, but it turns out that you’re the only guy in the entire school! Still, with a bunch of cute girls interested in you, this mission seems like it’s gonna be pretty good.

However, you soon learn that there’s more to this school than meets the eye. Turns out you’re not the only one trying to take out the headmaster. In fact, it’s an entire school of assassins! You manage to team up with three beautiful assassins each with their own set of skills to try to complete your mission, but it’s not going to be as easy as you thought…
