She appears to be set loose within a school in Kyoto to target a class of nine year old girls. At first she seems to succeed in frightening them but she ends up being defeated by the smart class performing a ritual song that transforms it into a frog.
After the ritual, the girls celebrate and exclaim (in Japanese) "The evil has been defeated. Now Kiko's spirit will live in the happy frog!" It was later revealed there were no fatalities. This angers Gary Sitterson who watches them on his monitor.
Appearance and CharacteristicsEditShe appears to be a stringy haired little girl in a ragged white gown, who floats around and screeches in a menacing manner. Her means of attack are never shown, and are most likely ineffective since none of the children in the classroom were killed in the Japanese ritual.
The monster is based on a piece of Japanese folklore called Yūrei, which are evil spirits originating from people who have been murdered or have committed suicide. They are not granted a peaceful afterlife and haunt people because of it.
