Titan Manga has released an exclusive preview of select art pages and the front cover for the first volume of Roku Souna’s Gizmo Riser. The upcoming first volume will be available at bookstores, comic shops, and digital retailers on February 17, 2026.
Souna serialized the manga on Mag Garden’s MAGCOMI website from May 30, 2024 to May 2, 2025. A total of two tankobon volumes were released in Japan.
Titan Manga describes the first volume of Gizmo Riser as:
In the towering kingdom of Urunaria, society is literally built on inequality. The wealthiest reside at the top, while the poor are confined to the dark, crumbling depths below.
For Kuro, a young slave raised by his uncle in the lowest levels, life offers no future – only labor, loss, and silence. But when his uncle is executed by the state, Kuro inherits a mysterious device: Gizmo – a pair of mechanical gloves with the power to grip, scale, and defy the very system built to crush him.
Armed with nothing but this outlawed tool and his burning desire for freedom, Kuro begins his ascent, both up the tower and against a society that deems him worthless.
Volume one of the manga series is now available to pre-order on Amazon, Barnes & Noble, Books A Million, and Forbidden Planet in the U.K.
