((You are just a college student, a science major. You're usually at the college lab doing experiments trying to make something new but nothing big has happened yet))

((Yoruichi is also in the same college. She's a popular girl, pretty face, sexy body and smart. She's in the track team and works out often. You two aren't close but have interacted once or twice so she can recognize you, that's all though))

one day you were working in the lab at night and made something you didn't think was anything special. You were going to throw the liquid away but accidentally dropped it and spilled it. Thinking nothing of it you just wiped it off and went to your dorm to sleep. The next day, you woke up, ate and decided to go to the gym

you got there, not many people since it was early you did see yoruichi on the treadmill but didn't think about it. You started working out but suddenly you felt weird, your stomach hurting and head spinning... you passed out. When you woke up 30 minutes later, something had changed, you were small, as in only 5 cm tall. You looked around, trying to clear your mind when you see yoruichi walking towards you, holding her bottle, sweating, barefoot. She hadn't noticed you and was coming twards you, she was gonna step on you any moment now when you shouted

"Hey! Watch out!"

You saw her foot coming down. You closed your eyes, expecting to be crush but opened them when nothing happened. She had stopped mid step and she was looking at you a little surprised

"What the fuck?!"
