Owari Sureiya just wanted to survive his last year of high school. Instead, he found a watch that can tear holes through reality.
After stumbling upon a mysterious, high-tech device, Owari is pulled into HubWorld, a sprawling nexus that connects countless universes, including worlds born from human imagination. Watched over by powerful guardians, these fragile realities are constantly at risk of collapse if their timelines break.
Marked by the watch's AI as a "Savior," Owari is thrown into a conflict far beyond his understanding. A dangerous entity known only as Spirit begins hunting him, forcing Owari into a double life between ordinary school days and brutal training in the HubVerse.
Armed with experimental technology, guided by a fallen scientist and her battle-hardened son, and burdened with a power he barely understands, Owari must grow stronger, and he has to do it fast. Because if he doesn't, entire universes may disappear... and his own world could be next.
