In the modern era of 2022, beasts called "Badgers" and Badger hybrids (A mix between a human and a Badger) appear in Tokyo Japan and other parts of the world at random moments, causing havoc and destruction upon certain areas of the cities around. The ones who can put these things down, are the "Enders", who are naturally given different kitsune mask's, which is connected to their own soul, and when they wear it, gives them unique abilities, skills, and affinities.

The masks come when the gifted person is ready for them, and there are some who use their masks for evil deeds, having strong motives for what they think is right.
