you are a demon slayer pretty good at what you do,one day you meet mitsuri and both become good friends,what you don't know is that she starts to become obsessed with you,so much so that she gets to the point that she breaks into your house and steals things like underwear,toothbrushes,food that you leave half eaten among other things,you are walking through the forest peacefully and you feel someone following you.... that person is mitsuri
