Insomniacs After School Anime Premieres
The television anime version of Makoto Ojiro’s Insomniacs After School (Kimi wa Hkago Insomnia) manga will debut in Japan in April 2023 on Tokyo TV and other television channels, according to a Monday announcement on the Big Comic Spirits magazine’s official website.

The main actors in the anime are:
- Gen Sato as Ganta,
- Konomi Tamura as Isaki
At LIDEN FILMS, Rintarou Ikeda (Science Fell in Love, So I Tried to Prove It, The Seven Deadly Sins: Imperial Wrath of The Gods) is supervising and penning the series scripts, and Yuki Ikeda is directing the anime. The characters are created by Plunderer’s Yuki Fukuda. The music is being composed by Yuki Hayashi (Haikyu!, My Hero Academia, Gundam Build Fighters).
In May 2019, Ojiro published the manga in the Big Comic Spirits issue of Shogakukan. On January 12, Shogakukan will release the manga’s eleventh collected book volume.
The first compiled book volume of the English-language manga, which Viz Media has a licence to publish, will be available on March 21. As stated by the business, the tale is:
As they seek refuge in the astronomy observatory at their school, two sleep-deprived teenagers discover kinship.
Ganta Nakami, who struggles to sleep at night, is irritable in class and unpopular with his peers. He finds that the school observatory, which was once used by the astronomy club but is now disbanded, might be the ideal place for a nap—but he’s not alone. Isaki Magari, a fellow insomniac who is willing to share the observatory with Nakami, sparks an unlikely friendship between the two of them.
The school observatory is a place where people avoid because of unsettling rumours about what happened to the astronomy club members, which makes it the ideal haven for Nakami and Magari to get some much-needed rest. Unfortunately, the faculty of the school cannot permit its unauthorised use. But if a new astronomy group formed, perhaps these two insomniacs would have a place to call their own!
Additionally, a live-action movie that will debut in 2023 is being inspired by the manga. 2019 saw the use of manga artwork in the music video for the song “Enshin” (Centrifuge) by the rock band Macaroni Enpitsu.
