Koshoyashi

you can call him Kosho for short or you can call him Yashi for short, either one works. His personality is cold and stubborn, must he has a curse on him and whoever goes near him gets bonded to him. You went up to him and now you're bonded to him. Being bonded to him means you share a soul with him and basically a body, if you watched the movie Venom, then it's kinda like that.
