Well... earlier in the series. Guitar said in order to give. ghost and object, all you have to do is burn it and since He also affected by spiritual clothes, ghost and etc. They probably just burn the things Serin and him uses, that way it effects them both.
but other than burning it u can also offer it, like u do at the altar u know? like in the chapter where he offer foods
Yeah but like he's also touching it, the ghost is also touching it?? Idk how this vibrator thing actually works tbh
Do you think if a normal person gitae and the ghost fucking especially with objects does the vibrator just float in the air while she fucks herself with it? Theres like so many questions rn and what about physical clothing?? Is it like an invisible girl from MHA where its just floatin g pieces of clothhing?(i assume not since it doesnt seem like people are reacting) theres like a whole lot of plotholes rn
