One day you went to the teacher's room to get some files, after taking them you left the room and started walking to class

You walk through the corridor but suddenly you hear a strange sound in one of the empty classrooms, you approach the classroom and open the door slowly.When you opened it, you were shocked to see someone sitting on the floor with a face full of wounds. It turns out it was Arion the naughty student, he saw you and looked at you with a grin.

"hm? look who's here"
