After moving there, Aoko Aozaki begins to learn sorcery from a young mage, Alice Kuonji, the rumored witch of the mansion.

Kinoko Nasu was inspired in late 1995 by the first episode of Neon Genesis Evangelion to write a novel, something he had been thinking of doing since he was in high school.

An enhanced version for Nintendo Switch and PlayStation 4 was announced in April 2022,[10] and published by Aniplex on December 8, 2022 in Japan.

While Nasu's stiff, wordy narration might be a turn-off, the characters and their interactions more than redeem it, and the primary conflict is engrossing and moving.

"[16] Siliconera said "Witch on the Holy Night tells a fun and engaging story with tons of well-written and fleshed-out characters" but noted "some issues with the English localisation in particular set it on the edge of accessibility" and that "extra commas and misspelled words do little to dampen one's enjoyment".

[17] Nintendo World Report said "it's a 12 chapter novel with high resolution graphics, full voice acting, and no discernible gameplay beyond changing how text is displayed" and called it "a well-written story that sets up a lot of things for the future" while noting that "most of the text is well translated; although a few typos were present ... they weren't occurring frequently enough to be a concern.

"[18] Hardcore Gamer called the novel "fun, but flawed" and criticized the pacing, saying "there are periods that just drag on", but also felt that "Witch on the Holy Night does earn its reading time."

[20] A two disc arrangement album featuring tracks from the game titled WITCH ON THE HOLY NIGHT ORIGINAL SOUNDTRACK REPETITION was released on December 29, 2013.

[21] Witch on the Holy Night's ending theme song is "Hoshi ga Matataku Konna Yoru ni" (星が瞬くこんな夜に) by Supercell, and was released with the game's soundtrack.
