Zashiki-warashi

座敷童子

A spirit girl (Vestal sprite) who has a crush on Watanuki.
Zashiki-warashi tend toward mischievous thoughts, yet this one is actually quite shy and sweet, and she cries very easily (those who make her cry will be attacked by her guardians, a group of tengu-karasu). She lives on a mountain with pure spiritual energy and, as a result, is vulnerable to evil energy.
She is based on a spirit from Japanese folklore, the zashiki-warashi, which accounts for her childlike naivety and innocence.
