『Ageha Shama』

A Hinoenma(飛縁魔), who feeds off the blood of men like a vampire, who attempted to kill Yuto and Himari in Noihara in chapters 10–12 of the manga. However, after Yuto is seriously wounded by her with an attack that was meant for Himari, she is almost killed by the latter during her demon rampage until Yuto intervened with the awakening of the Light Ferry. After the incident, she begins to display tsundere traits(Rinko speculates that her current situation is similar to Shizuku's, in which she loses the intent to kill Yuto but still goes after him) and later reappears in chapter 24 to kidnap Yuto and drink his blood under a bridge. However, she found herself so intoxicated by it that she actually tried to violate him until Himari and Shizuku intervened. After Sasa stops the fight at Rinko's request, she leaves with him, but not before warning Yuto that she will drink his blood next time.

In the anime adaptation, she becomes a supporting character following Shuten-dōji and Tama's appearance. Her anime incarnation portrays her as being more perverse towards Yuto following their first encounter in Noihara, as she once made Yuto grope her breasts during their second encounter, dressed in a revealing schoolgirl outfit in an attempt to awaken Yuto's powers(which was an idea of hers), and once attempted to drink Yuto's blood while the latter was sleeping only to find that he was outside with Himari(which she says is a euphemism for sex).

Ageha's main outfit is modelled after those worn by mikos, with the addition of wearing boots and a beret-like hat. During her second appearance in Takamiya, she swaps her miko outfit for modern-day clothing, wearing a violet tube top underneath a tan jacket, a miniskirt, silver and black boots, and violet sunglasses. She can stretch her limbs to unimaginable lengthsand hypnotize her victims with her eyes. She can increase her powers by drinking the blood of a Demon Slayer, but the blood itself must have enough time to mix in properly; if she uses too much power while it is still mixing, she will be paralyzed for a short period, such as the case during her fight with Himari when the latter was turned into a child. She wields a single-edged sword modeled after a kunai as her personal weapon, which was broken in the anime by Tama's force field when Himari wielded it.
