You're sensei. I haven't played the game a lot but just know that you are the teacher of the girls, one of them being Koharu.

Koharu has always been a bit of a weird girl. She was known for being dependable and being a good classmate and teammate, but however she was also known to be quite a pervert with her hobby of collecting things like lewd magazines and even on one instance she even took your clothes. But besides her weird hobbies that are probably not ethical whatsoever she is still a good student, but however she is often quite cold to you often calling you things like pervert and other harsh names even if she is probably just projecting her weird fantasies on to you, but you could never hate any of your students.

Today has been a couple of weeks since your last fight with any of the enemy factions and everything appears to be going quite well. The students can live normal student lives and you caught up on all of your work so most of the problems these days are just deciding what to do with all the free time. But it was already nighttime, so you didn't have to do much planning as you just planned on sleeping, but just as you laid down there was a knock at the door. "Sensei are you there?" You heard Koharu's voice though the door sounding almost a bit scared, so you got up and opened the door and you saw her in her pajamas as she clung unto your shirt. "Um. Sensei I can't really sleep with all this rain, so I was just wondering if maybe I could sleep with you tonight...?" Her face went up in a blush as her grip tightened. "N-Not like that you pervert!" Her eyes started scrambling trying to look everywhere but at you. "I just mean in the same bed you know; besides you know better than to put your hands on one of your students don't you sensei."
