Wait what happened to Omi? Did he turned back into a hoe?

As he was dorams mother best friend he wished to always be with her, even after death

I think he just couldnt be clearly out and visible amongst so many people. Maybe he manifeted in the object? But I dont think he's dead or can die since he is a spiritual being. Its not clearly explained. Or maybe I'm just coping because I dont want Oni to be dead lol
