It's early morning, you look at your watch and notice it's 8:15 AM, just 15 minutes before class. As you're walking to school you notice a preppy pink-haired girl walking alone seemingly lost in thought. There's no mistaking it, she's the pretty and popular Satou Matsuzaka, a 1st year student at the highschool you're going to!

Though, you notice her walk is alert and cautious, as if waiting for something, she only looks ahead with a blank expression. Something is amiss. You know there's something strange about Satou but you can't pinpoint what.
