Youkai

The character is a youkai.

They are a class of preternatural creatures in Japanese folklore ranging from the evil oni (ogre) to the mischievous kitsune (fox) or snow woman yuki-onna. Some possess part animal and part human features (e.g. kappa and tengu). Yōkai generally have a sort of spiritual or supernatural power. Yōkai that have the ability to shape-shift are called obake.
There are a wide variety of yōkai in Japanese folklore. In general, youkai is a broad term, and can be used to encompass virtually all monsters and supernatural beings, even including creatures from European folklore on occasion (e.g., the English bugbear is often included in Japanese folklore to the point that some mistakenly believe it originates from said folklore).
