This system is believed to interface with concepts rooted in Japanese folklore such as 怨霊 (Onryō) — vengeful spirits — and karmic retribution (因果応報).
Entities classified as Onryō manifest through unresolved hatred. Visual correlation observed with 地獄少女 (Jigoku Shōjo) phenomena reports.
Historical reference: 丑の刻参り (Ushi no Toki Mairi) — ritual curse performed at the Hour of the Ox using symbolic effigies.
