This is a tough one. PLEASE HELPPP

I think it was a yaoi manga I read ages ago that I’m looking for it might not be tho it might of been a girl. It was a person living with loads of spirits but they weren’t a spirit them self so they had to wear a mask to blend in with them. One of the scenes from the manga was they went for a swim and the water went black because the god that lived in it was corrupted and had to be cleansed. PLEASSSEEE HELP ME FIND THISSS
