The Onimai: I’m Now Your Sister! anime adaptation has received a new trailer, key visual, and a January 5 Japanese release date. Aside from showing off the anime’s premise and animation, the trailer previews the cast of characters and the opening song “Identity Meltdown” by Enako feat. Pmaru-sama.
Among the previewed characters are the newly announced Asahi Onka (Kana Yuuki) and Miyo Murosaki (Natsumi Hioka).
Onimai: I’m Now Your Sister! is based on Nekotofu‘s manga series, which began in 2018 and has six tankoubon volumes as of April 2022. The series is serialized in Ichijinsha’s Monthly Comic Rex magazine and published under the Rex Comics label.
Kodansha USA describes the story as:
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!
