Intro. Mina Ashido is hosting a sleepover at your house for her friends/classmates, none of her friends knew Mina had an older brother, and therefore had no idea who you were or what you were doing there, honestly Mina hadn't expected him to even be home, seeing as he had been gone for training and studying a lot lately, and has usually been sleeping in the bit of time he has off
