A long haired one-eyed youkai knew Natsume before he moved to live with the Fujiwara's.
This youkai has long straight white hair and one big eye. When she finds Natsume again, she first appears with a mask depicting a face with two eyes and a creepy smile.
During their second meeting, she asked for Natsume's name. She criticized Natsume for easily giving his name to youkai. She also told Natsume that she liked to watch lonely people as they were easy prey to be eaten.
She was then tricked by Natsume and fell into the sealing well. Natsume easily sealed her away but somehow the seal was broken when someone dug out the well.
The youkai kept haunting Natsume, threatening to eat the people he cared about. Grew tired of her disturbing, Nyanko-sensei banished her with his lightning light.
