I hope it has dream/demon sections depending on whether you chose samurai or ninja, like how you get new abilities, you have to go through a stage of 'enlightenment' (or dream like mini boss sections to acquire these abilities) these will differ depending on the path you chose (samurai/ninja, light and dark)
Japanese folklore is crying out to be used in this way in ghosts, but not in the standard story part, since that looks grounded, which it should
Be a nice escape
I'm clutching at straws I know
