Titan Manga continues to expand its catalog with another exciting acquisition. The publisher announced it will release Gizmo Riser, a 12-chapter action-packed manga by Roku Souna, in English starting April 28. The first volume is already available for pre-order in the U.K. and will soon be accessible through North American retailers.
The news comes just weeks after the manga concluded its run on Mag Garden’s Mag Comi website. With its compelling underdog story and striking visuals, Gizmo Riser is poised to attract a new international audience.
Story So Far
Set in the towering kingdom of Urunaria, Gizmo Riser presents a world where society is physically and socially stratified. The wealthy elite live in luxurious heights, while the poor toil in the crumbling, oppressive depths below.
The protagonist, Kuro, is a young slave raised in these lower levels by his uncle. Life offers him nothing but hardship and silence. However, everything changes when the state executes Kuro’s uncle, leaving him a forbidden inheritance: Gizmo — a pair of powerful mechanical gloves capable of scaling walls and manipulating the environment. With this tool and an unbreakable spirit, Kuro embarks on a dangerous climb toward freedom, challenging a system designed to keep him down.
Publication Background
Roku Souna launched Gizmo Riser on Mag Garden’s Mag Comi platform in May 2024. The series concluded on May 2, 2025, with 12 tightly plotted chapters. Despite its short length, the series has garnered praise for its world-building, fluid action, and themes of resistance and empowerment.
Souna is also the creator of Yorunoko – The Doom Liberators, an ongoing series on DeNA’s Manga Box app, further building their reputation as a rising voice in action and sci-fi manga.

Kuro
A determined and resourceful young slave from the lower depths of Urunaria. After losing his uncle, Kuro inherits the outlawed device Gizmo. Fueled by grief and a thirst for justice, he uses the gloves to fight his way upward through the oppressive tower.
