A tree spirit that grows in areas where mass amounts of human blood were spilled on the ground, such as battle fields or execution sites. They sucked up so much of this blood that they turned into demons. These trees, having sucked up human's blood to be born, will bleed when they're cut. They are sturdier than other trees and heal their wounds quickly. It's said that their branches, if obtained with permission, can be used as powerful healing and cleansing items. They may hide among bushes and trees and can organize themselves to make someone lose their way in a forest, through communication.
