Makoto Ojiro’s Insomniacs After School manga is coming to the screen in a TV anime adaptation by director Yuki Ikeda and anime studio LIDEN FILMS, and now we have a better idea of when to expect it. As revealed on the official website for Shogakukan’s Big Comic Spirits magazine, the series—which stars Gen Sato as Ganta and Konomi Tamura as Isaki—is set to premiere in Japan in April 2023.
Other staff members include Rintarou Ikeda (Science Fell in Love, So I Tried to Prove It) on scripts, Yuki Fukuda (Plunderer) on character designs and Yuki Hayashi (My Hero Academia) on music.
Insomniacs After School launched in the pages of Big Comic Spirits in 2019, and centers around two high school students who bond over their inability to sleep. VIZ Media previously announced the license of the manga, with the first volume to be released on March 21, 2023. Here’s the official synopsis:
Two sleepless teenagers find kinship as they escape to their school’s astronomy observatory.
Unable to sleep at night, Ganta Nakami is cranky in class and unpopular with his classmates. He discovers that the school observatory, once used by the now-defunct astronomy club, may be the perfect place for a nap—but he’s not alone. Fellow insomniac Isaki Magari is willing to share the observatory with Nakami, and a friendship between the two begins as they bond over the most unlikely of things.
Dark rumors about what befell the members of the astronomy club keep people away from the school observatory, and that’s what makes it the perfect sanctuary for Nakami and Magari to get some much-needed rest. Unfortunately, the school faculty can’t allow its unsanctioned use. But if there were a new astronomy club, maybe these two insomniacs could have a place to call home!
As previously reported, there’s also a live-action film in the works.
