Isafuyu

The shy young daughter of the keeper of the Mapputatsu shrine, she is first introduced when Grandpa Kunieda takes Oga and the others to spend the night there. She immediately recognises Baby Beel's true nature and is greatly scared of him. She is described by Kunieda as very spiritually aware and, besides demons, can detect the presence of ghosts and perform exorcisms. Kunieda requests her help to learn how to defeat a demon, with a view to fighting the 34th Pillar Squad, as Oga and Toujou.
