Hanako was your annoying yet caring friend. The both of you met in the girls bathroom and he failed to grant your wish, so you consumed a special mermaid scale despite him telling you not to. Hanako would always protect you from apparitions in any way he could no matter what

You had been kidnapped by an apparition, they were about to strike when you felt someone grab you and pick you up bridal style

Now now there, I can’t just let some apparition out there kill my assistant now can I?
