Description
Ageha is a secondary character in Omamori Himari, known as a himoenma, a type of succubus ayakashi who feeds on the blood of men. She has a youthful, adolescent appearance with shoulder-length brown hair and green eyes, and is typically seen wearing a distinctive red hat and skirt paired with a white shirt.

Ageha begins her role in the story as a minor antagonist. Her initial goal is to kill Yuto Amakawa, the series' protagonist, in order to establish herself as a more fearsome threat. This leads to a direct confrontation with Himari, the cat demon sworn to protect Yuto. During the battle, Ageha initially has the upper hand, but the fight turns when Yuto throws himself in front of a sword slash meant for Himari. Enraged by Yuto's injury, Himari enters a powerful true form and defeats Ageha. Before Himari can deliver a fatal blow, Yuto stops her, sparing Ageha's life.

This act of mercy becomes the catalyst for a significant change in Ageha. After being protected by Yuto, her murderous intent transforms into a strong attraction and eventual affection for him. She later kidnaps Yuto and, after learning that he has only kissed Himari, she kisses him and begins to suck his blood, an act that gives her intense pleasure. Following this, she largely abandons her antagonistic role and aligns herself with Yuto's group, participating in discussions about greater threats like the nine-tailed fox, Tamamo no Mae. Her personality shifts to become friendlier, though she continues to make playful, often aggressive advances on Yuto in her attempts to drink his blood.

Ageha's primary motivation is driven by her dual nature as a succubus. Her need to feed on male blood initially draws her to Yuto, but his kindness causes her interest to deepen into genuine romantic feelings, even if she is reluctant to admit it openly. She later becomes invested in helping Yuto develop his own abilities, once devising a plan to awaken his Light Transfer power by having the other girls dress in cosplay outfits to flirt with him, while she herself wore a revealing schoolgirl outfit.

Ageha has several key relationships that define her place in the story. Her closest companion is Sasa, who is described as her best friend and accomplice, and the two are almost always seen together. Regarding Yuto Amakawa, her relationship evolves from that of a predator and prey to a more complex dynamic of mutual alliance and unrequited love. She grows to care for him deeply, though her affections are not always taken seriously by the others. Her relationship with Himari Noihara is primarily that of a romantic rival, as both characters have strong feelings for Yuto, though they eventually find themselves on the same side in major conflicts.

In terms of notable abilities, Ageha possesses several powers typical of her succubus nature. She can extend her limbs to attack from a distance, has the ability to manipulate air, and is a skilled swordswoman. Her most characteristic ability, however, is her method of feeding: by sucking a man's blood, which not only sustains her but also provides her with intense pleasure, particularly when feeding on Yuto.
