Relationships

 * Kousuke Endou - Hidzuki is absolutely infatuated with Kousuke after he defeats her in combat while she is in a feral state in Fairy World. After reuniting with Kousuke on Earth, Hidzuki wishes to be forever bounded to him. However, because of her status as an oni, this translates to her wishing to eat him at some point. Kousuke vows to fight her with all his being if ever she tries to eat him, to which Hidzuki decides to be supportive to him after seeing the bonds forged between him and his other fiancées.
 * Hinata Fujiwara - The two are initially hostile towards to each other due to their respective positions, but they soon set aside their mutual animosity when Hidzuki vows to be Kousuke's ally.

 * Lana Haulia - As Kousuke's first betrothed, Hidzuki initially sees Lana as a rival for Kousuke's affection, but she later accepts Lana's standing after seeing her determination when she confronts her. Lana considers Hidzuki to be as frightening as Shea, but still refuses to back down in front of her for Kousuke's love.
 * Aularodde Lea Refeat - Hidzuki holds Aularodde in high regard as the former goddess of their world.
