Isafuyu (諫冬, Isafuyu) (or Isa-chan as Aoi calls her[1]) is the daughter of a priest of the Mapputatsu Temple, where she lives and works as a priestess.


Isafuyu is a short petite girl who often dresses in her priestess clothes. She has purplish-red hair tied in two loose pigtails and matching eyes.


Isafuyu is very shy. She also appears naive and innocent, answering the perverted questions that Koma asks her without appearing bothered by them (she simply states that they're just personal things).


Isafuyu has known Aoi for a certain period of time and have become seemingly close, as shown by how they refer to one another with "-chan" suffixes.


She is first introduced when Ittōsai Kunieda takes Oga and the others to spend a night at the Mapputatsu Temple. She immediately recognises Baby Be'el's true nature and is greatly scared of him.

Kunieda requests her help to learn how to fight against demons in order to fight Behemoth's 34 Pillar Division along with Oga and Tōjō.

In order to help Kunieda, Isafuyu takes her to see Koma, a Demon who lives near the Mapputatsu Shrine.

Powers & AbilitiesEdit

Isafuyu is spiritually aware and can can tell whether a person is a Demon just by looking at them. She was able to tell that Baby Be'el was a Demon and a very strong one too. Other than Demons, she can also detect the presence of ghosts and can also perform exorcisms on Demons and ghosts. She was often assisted by Koma in fighting Demons.


Aoi KuniedaEdit

She and Kunieda are on close enough basis to call each other by their first names with "-chan" affixed.


"Welcome home, Aoi-chan!"
