Tsukasa Kudamaki

Kuda-gitsune (管狐 "pipe fox") are mythological beings associated with foxes, weasels, or larval rollers, small enough to fit inside a pipe or bamboo tube. According to tradition, they answer questions to those who conjure them up, or take possession of people. In Touhou, however, the main interpretation shown is that kuda-gitsune first bring wealth, but over time multiply in such a way that they harm their owners, whether through high financial costs as in traditional mythology, or by stealing their life force as in Touhou Project. For example, in Chapter 8 of Wild and Horned Hermit, Reimu Hakurei temporarily falls victim to a trick by a kuda-gitsune who steals Reimu's life force. Kuda-gitsune are also called iizuna (飯綱 'fox spirit'). This is the same iizuna from Megumu Iizunamaru's surname.
