So I understood this chapter as, according to Shijin, the MC is a living poison that can kill yokai (which they want because they’re stuck in a permanent cycle of reincarnation that drives them mad?) because as a little kid he stole the “poison” from Shijin with the help of a yokai (maybe Yae the tall Yokai with the hat from the last chapter?).
So does Shijin serve like, the top of the food chain yokai or something?
