Eika Ebisu

Eika is the spirit of a mizuko- meaning a child that was either stillborn, or only lived for a short time. Like all such spirits, she exists in limbo at the Sai no Kawara and spends her time stacking stones into towers. Though Japanese folklore portrays the spirits' situation as tragic, Eika enjoys her work immensely and sees the Sai no Kawara as a "kingdom" where she and the other spirits can play freely. She's adored by her fellow spirits, and routinely arranges stone-stacking contests for their enjoyment. She is described as being both cheerful and intelligent, though she also displays fierce bursts of emotion that one might expect from a young child. When the protagonists of Wily Beast and Weakest Creature knock over the stone towers while passing by, Eika is outraged on behalf of her fellow spirits and makes a threat on the protagonist's life. At the same time, she's also very flexible and quick to make the best of a bad outcome; once the protagonists leave, she casually accepts the situation and wastes no time in arranging a different type of contest instead.
