Shingo Fujii (Mushoku Tensei: Jobless Reincarnation episode 11 storyboards, director) is making his series directorial debut with the anime at Studio Bind.

Multi-genre entertainer P Maru-sama and cosplayer Enako are collaborating to perform the opening theme song "Identeitei Meltdown," while the "Onimai Sisters" (the main characters' voice actresses: Marika Kōno, Kaori Ishihara, Hisako Kanemoto, Minami Tsuda), perform the ending theme song "Himegoto * Cry Sisters."
Kodansha Comics is publishing the manga digitally in English, and it describes the story:
Mahiro Oyama was just a normal erotic-game loving dude...until he woke up one morning as a woman! Turns out his mad-scientist little sister, Mihari, tried out one of her new experiments on him...with a disastrous outcome, as far as Mahiro's concerned! But Mihari is as determined to study him as he is determined to go back to his shut-in, game-playing life, and one thing's for sure...life is going to get a whole lot weirder from here on out!
The manga began as a self-published work by Nekotofu in 2017, which they published through pixiv and other places online. Nekotofu launched a regular serialization of the manga in Ichijinsha's Comic Rex magazine in April 2019. Ichijinsha published the manga's sixth compiled book volume and its second anthology volume on the same day on April 27. Kodansha Comics released the sixth volume in English on October 25.
