A completely new one-shot for Himouto! Umaru-chan is on the way. Titled Himouto! Umaru-chan 100, the 16-page story will be published on Yanjan+ on October 1, 2026, marking the first all-new work for the series in about eight years. A limited campaign will also offer all 13 existing volumes at 100 yen each.
First New One-Shot in About Eight Years
The original Himouto! Umaru-chan manga ran in Shueisha’s Weekly Young Jump from 2013 to 2017 and inspired TV anime adaptations in 2015 and 2017. The popular series has more than 3 million copies in circulation. The new one-shot is fully newly drawn by Sankaku Head, and it is the first new work since the 2018 spin-off series Himouto! Umaru-chan G.
Title Tied to Shueisha’s 100th Anniversary Project
The title Himouto! Umaru-chan 100 is connected to a campaign held as part of Shueisha’s 100th anniversary project. At e-bookstores, the 12 volumes of Himouto! Umaru-chan and the single volume of Himouto! Umaru-chan G, 13 volumes in total, will be sold for 100 yen each.
Campaign Period and Participating Stores
The campaign will run from 0:00 on October 1 to 23:59 on October 10. It is planned for Yanjan+, Zebrack, and other e-bookstores.
Fans can look forward to both the first completely new Himouto! Umaru-chan one-shot in about eight years and the limited-time chance to enjoy all 13 existing volumes at a special price.
