A spin-off manga titled Himekami no Miko (姫神の巫女) started serialization in the July 2020 issue of ASCII Media Works' monthly Dengeki Maoh magazine.

[3] Himeko Kurusugawa and Chikane Himemiya are two high-school girls at the prestigious Ototachibana Academy in the fictional Japanese town of Mahoroba.

The Orochi awakens on the first day of October (Kannazuki, "the godless month," in the traditional Japanese lunar calendar), Himeko and Chikane's shared birthday.

Orochi gave its followers great physical strength and endurance, a limited capacity for teleportation and levitation and an individual power (or weapon).

The god chooses its followers from those who have experienced great pain in their lives and have surrendered to despair; they include a sociopathic criminal, an unintelligent brute, a former Japanese idol, an anti-social manga artist, a catgirl, a seemingly traitorous friend and a disillusioned nun, with only one of them, the criminal's brother, being able to temporarily resist the god's influence completely.

The license was transferred from Geneon USA to Sentai Filmworks in 2009; the latter reissued the series in a DVD box set on August 25, 2009.

Voice actors included Noriko Shitaya (Himeko) and Junji Majima (Sōma Ōgami), who are currently hosting RADIO Kyōshirō (RADIO京四郎).

[10][11] Carl Kimlinger, also of ANN, described the series as having a strong and emotional conclusion, but also called it "pure poison for the melodrama-averse.

"[12] Theron Martin, another ANN writer, praised the development of relationships between characters and the musical score, but criticized the mix of genres, "logical inconsistencies, [and] weak animation.

"[15] In her review of the series, Erica Friedman (president of Yuricon) criticized the story for its rape scene and its manga ending (in which Chikane and Himeko are reincarnated as sisters and lovers),[16] considering it poorly written.

She asks why, "if both [Sōma] and Chikane love Himeko so much, do they allow her to be bullied, outcast and victimized instead of stepping up and claiming their friendship publicly?

[18] He described later sets of episodes as bringing interest and depth to the characters, and argued the series "comes to a strong and emotional ending.
