Working my way through Kuon. There are definitely vengeful ghosts, and there are gaki… Gaki are zombie-looking goblin-ish creatures, but the internet tells me they are a type of spirit (something akin to the various “hungry ghosts” found in East Asian folklore and Buddhism). I suppose I can at least cross off “ghost” for this one, and probably “monster.” Plenty of people have been killed too, and chances are I will eventually find someone behind all this and can properly land me a “killer.”
I’ll have to notice if there’s a graveyard of some kind.
