Wholesome chapter with Michiru i hope her tentacles still protect Miko even tho it retracted a bit also what plot twist on that mid aged ghost i think that thing is also related to Miko's dead father cos i think that ghost is a bad omen of some sort but then again im just throwing some thoughts...
This kinda reminds me of Fatal Frame series mainly the Crimson Butterfly and Maiden of the Black Water with the whole shrine maiden ritual gone wrong thing.
