Sankakuhead's cultural phenomenon Himouto! Umaru-chan is officially staging a triumphant return. Shueisha has announced a brand-new, completely original 16-page one-shot titled Himouto! Umaru-chan 100, marking the franchise's first fresh manga chapter in roughly eight years since the conclusion of the Himouto! Umaru-chan G spin-off series in 2018.
The upcoming special chapter is scheduled to launch on the Yanjan+ digital platform on October 1, 2026. This special release serves as part of a commemorative campaign celebrating Shueisha's 100th anniversary, tying the numeric milestone directly to the iconic title of the new one-shot.
A Decade of Otaku Culture and Couch-Potato Antics
Originally serialized in Shueisha's Weekly Young Jump from 2013 to 2017, Himouto! Umaru-chan captured the hearts of readers worldwide with its hilarious dual-life premise. The story follows Umaru Doma, a pristine high school student admired by everyone, who transforms into an absolute gremlin of an otaku obsessed with video games, junk food, and anime the moment she walks through her front door. The manga's massive success propelled it into two critically acclaimed television anime adaptations produced by Doga Kobo in 2015 and 2017, cementing its status as a defining comedy of the 2010s.
Massive Digital Discount Campaign
Alongside the premiere of the new one-shot, fans will have a golden opportunity to catch up on the entire series. Shueisha is launching a massive promotional discount across major electronic bookstores, including Yanjan+ and Zeblack. All 12 volumes of the original main series and the single volume of Himouto! Umaru-chan G—totaling 13 volumes—will be marked down to just 100 yen each.
The discounted reading campaign runs for a strictly limited window, starting on October 1 at 0:00 and concluding on October 10 at 23:59. Whether readers are revisiting Umaru's chaotic household shenanigans or discovering her legendary cola-and-potato-chip routine for the first time, October 2026 promises to be a nostalgic celebration for fans of modern slice-of-life comedy.
