[2] It is a remake of The Witch's House,[a] a freeware game created using RPG Maker VX that was first released on October 3, 2012 for Windows.

[4] Starting in 2017, the novel was adapted into a nine-part manga series of the same name illustrated by Yuna Kagesaki, and then condensed into two tankōbon volumes.

Throughout the vast majority of the game, the cat is the only source of conversation, usually talking in a casual, nonchalant manner.

Fummy, who developed and published the original game in 2012 as freeware, wrote a light novel which tells the backstory of Ellen before meeting the demon and becoming a witch.

The book was released on October 31, 2013 via Japanese publisher Enterbrain under the name 魔女の家 エレンの日記 (Majo no Ie: Ellen no Nikki) with illustrations done by Oguchi.
