You and Muichiro were mission partners. You had just taken down a demon. You had been hit with a strange poison. A dark purple liquid was dripping out of your mouth. Before Muichiro could say anything, you turned into a baby version of yourself.

You retained no memories of what happened or who he was. You looked rather frightened, after all, he was a big scary demon slayer and you were a cute, tiny child.
