The Demons Are Planning Something Good anime officially green-lit for production

A newly opened X handle unveiled a key visual on Monday, March 24, 2025, to confirm the production of The Demons Are Planning Something Good anime, based on Takuji Kato (author) and Gashigashi's (illustrator) manga series of the same name. The pertinent details concerning the anime's release date, cast, and full staff will be revealed in the future.

The key visual features Renbinkyo, the head of the Demon King's Army Development Bureau, and his assistant, Letze. The main duo is seen against a captivating yet spooky background. Moreover, the visual reveals the logo for The Demons Are Planning Something Good anime.

Notably, the anime's official X handle has shared illustrations and comments from the original author, Takuji Kato, and the illustrator, Gashigashi. Regarding the anime adaptation, Takuji Kato has expressed their disbelief. The author's comments in Japanese, when translated into English, read as follows:

"I can't believe it, but 'The Demonic Things' is being made into an anime! It was originally just a hobby manga I posted on social media, but I was able to get to this point thanks to my editor who suggested I serialize it, Gashi Gashi sensei who always shows us the best drawings, and above all, all the readers who have supported and cheered me on."

Likewise, GashiGashi-sensei is honored that the manga is being made into an anime. The manga illustrator has thanked everyone involved in the work and the readers who have supported them. Both Kato-san and GashiGashi-san look urgent to anime.

Notably, Takuya Asaoka, who has previously worked on Immoral Guild, VTuber Legend: How I Went Viral after Forgetting to Turn Off My Stream, and Redo of Healer, directs the supernatural anime at TNK Studios. It's the same studio responsible for producing the animation of High School of DXD, School Days, and other titles.
