Anyingnyanniichuan

One of the many Jusenkyou Springs on the island, Anyingnyanniichuan is also known colloquially as the "Shadowgirl" spring. Those affected by its waters transform in ways that seem to involve the element and creation of shadows. For example, recipients of this blessing often appear to be shrouded in constant shadows; many find a shift towards dark or gray-tinged shades in hair, eye, and skin tones.

Folklore

This spring is believed to be sacred to the Yuriban goddess Tsuki. Many believe that the spring also tends to carry Tsuki's influence with it, making people with the Shadowgirl blessing more prone to depression, sadness, and other darker emotions. While some seem able to wear it with minimal effect, a disproportional number of those who wear it find cause to remove it after a matter of weeks or months.
