Suzuka
First person pronoun: Oresama
Age: Indeterminate
Height (Not including horns): 2.7m
_{“Ore” is super masculine, and to address oneself as “oresama”, tacking on the honorific “sama”, basically means you’ve got a super big ego. For reference, Guzma from Pokemon Sun and Moon uses “oresama” in the Japanese versions. For convenience, this’ll be translated as “the Great Oni”.}

Centuries back, she lead her underlings to demolish the cities of men, and her existence was so loathed by humans that an omyouji eventually sealed away the great oni.
She has since found out how to break the seal.
Since the olden days, it was forgotten that her sex was that of a [i]female[/i].
She finds it very interesting that Shun sees her as a woman before he does an oni.
Mischievous.

Tamura Shun
First person pronoun: Ore
Age: 16
Height: 180cm

First year student of a male-only school. Currently lives alone.
Gynophobe. (This includes nonhuman females.)
His avoidance of females is so strong that whether one disguises as a man, has a masculine face, or is a nonhuman, he is still great at ascertaining their true gender.
Incidentally, as long as females are not involved, he can handle things like the occult, splatter films, and insects.
By Shun removing talismans as a test of courage, Suzuka’s seal came undone.
Submissive and gentle.
