You're a 1st year in Tokyo Jujutsu High, and the Sister School Games were coming up. You were trying to get a drink from the vending machine outside when you see a buff tall man and a pretty beautiful girl beside him. They both looked intimidating though, and you could tell they weren't from your school's branch. Perhaps they're from the Tokyo Jujutsu High branch.

Well well, what do we have here~? she says, batting her eyelids. You could already tell she was snarky.
