Sentai Daishikkaku, the latest manga from Quintessential Quintuplets creator Negi Haruba, is going on indefinite hiatus due to the author's "poor health."

As reported by Anime News Network, the hiatus and the reason behind it was announced in the latest issue of Weekly Shonen Magazine. Specifics regarding Haruba's condition and when the manga is expected to resume were not given. As its name suggests, Sentai Daishikkaku is a series inspired by tokusatsu series' like Super Sentai, which was later adapted for Western audiences as Power Rangers. The manga takes place in a world where the Earth is constantly threatened by an alien race of monsters, and the only thing standing in their way is a team of masked warriors known as the Ryujin Sentai Dragon Keepers. Haruba's new series premiered in February, and the series' second compiled volume was released in June.

This is not the first time a popular manga creator has taken a health-related hiatus this year: The popular shonen manga series Jujutsu Kaisen was put on a two-month hiatus in June when editors expressed concerns over the long-term health of series creator Gege Akutami, who reassured fans that the condition wasn't serious and that their mental health was fine. Concerns over the harsh hours manga creators often have to work in order to meet the industry's tight deadlines and the effect that has on their overall health have received extra attention ever since the unexpected death of Berserk creator Kentaro Miura in May. Miura passed away at age 54 due to an acute aortic dissection.

Haruba is best known for creating The Quintessential Quintuplets, a romantic comedy manga that was serialized from 2017 - 2020. The series tells the story of Futaro Uesugi, an academic gifted student who is saddled with his father's immense debt, who agrees to tutor the five daughters of the incredibly wealthy Nakano family. The story reveals in its opening chapter that Uesugi will eventually go on to marry one of the five sisters, and leaves readers guessing throughout the series which one he will end up with. The series won a Kodansha Manga Award in 2019 and was also the fifth highest-selling manga title in Japan for that year.

The Quintessential Quintuplets was adapted into a 12-episode anime series in 2019, which was followed up with a second season in 2021. The first season was produced by animation studio Tezuka Productions, which is best known for their work on classic anime such as Astro Boy and Black Jack, as well as newer hits such as How to Not Summon a Demon Lord and Girlfriend, Girlfriend. The second season was produced by the relatively new company Bibury Animation Studios, which produced the anime adaptation of the Azur Lane game series.

Both seasons of the anime series are available for streaming on Crunchyroll.
