The The Great Jahy Will Not Be Defeated! (ジャヒー様はくじけない！ Jahy-sama wa Kujikenai!?) anime was announced on April 16, 2021, and is scheduled to premiere on July 31 of the same year.
The Great Jahy is the Dark Realm's feared No. 2, a proud being who's only a single spot away from the great Demon Lord.
Feared by even her fellow demons, she enjoys a life of all-you-can-eat luxury, until one spring... when the Dark Realm is suddenly attacked by a Magical Girl, and Jahy's blown away into the human world!
Having lost all of the power and beauty she once had, she's turned into a small human girl, her only hope of restoring her realm lying in the magic stones she must now find in the human world.
Forced to live in hardship, she resides in a tiny 4-and-a-half tatami mat apartment without even a bath, and works part-time at an izakaya just to get by.
Even with work, rent reminders and her quest to restore the Dark Realm to its former glory hanging over her head, The Great Jahy swears she will not get discouraged!
