Haozhunyaniichuan

Haozhunyaniichuan (Spring of Drowned Porcupine Girl), a Jusenkyou Spring, grants those that are doused in its waters the form of a female with some porcupine-like attributes. While not many have managed to come across its waters, it's suspected that these attributes will include quills to some degree. Perhaps some of its facial features will be seen as well. There's no known goddess or legend associated with Haozhunyaniichuan.
