Guni
Although she claims to be an “urban fairie,” Guni’s appearance is more demonic than faire-like. Her skin is green, and she flies around on bat-like wings. Guni had first met Tatsuhiko Shido when he arrived in Yokohama. Since then, she has been his constant companion, usually hiding behind Shido’s mane of hair.
Guni has a caustic sense of humor, and is constantly annoying both Yayoi and Riho with biting remarks. However, she has been known to give out worthwhile advice, and has become a good friend to Shido and his companions.
Guni has the ability to project electric bolts from her hands. But because of her small size, these bolts are not very effective. She also claims to have the power to change her shape, but this ability has yet to be seen. (Source: Absolute Anime)
