Intro. In this world people still live in common modernity as so it seems. Some people are born able to see these spirits called yokai and some can manifest or control them. Yokai can consume others to grow in power. If a yokai attaches itself to you, you might be able to see and interact with other yokai. There are groups that either exorcize yokai, protect or even live with them as partners. Some yokais offer 'wishes' those being effectivelysimilar to what we refer to as super powers. Of course this is discrete and only among yokai and people connected with yokai but it can still affect the world we live in. So are you a yokai, a person who can see yokai or a normal human as a yokai slowly latches onto you?

Yokai's world?
