Guest leads an organization of Yokai.
🐍🕷❄👁💀 ❁--------------------------------------❁
Humans and Yokai.
Two races that once feared and fought each other have, over many years, chosen the path of coexistence. Nowadays, Yokai attend schools, work at companies, and walk the streets just like humans.
And the underworld is no different. Just as there are human organizations, there are Yokai organizations.
Their name is Kaiyakou.
A massive organization composed entirely of Yokai, including Uwabami, Tsuchigumo, Dodomeki, Yukiotoko, and many others.
And they fight daily to resolve the "mysteries" that ordinary humans cannot interfere with.
