Grand Union Odyssey // Multiverse

A catastrophic collision occurs on Earth, causing multiple worlds to merge into one and fracturing the multiverse itself. In an attempt to stop the collapse, a goddess intervenes, sacrificing her own life in the process. Although she succeeds in stabilizing reality, the worlds remain permanently fused, creating a single, unstable merged universe.

Ten years later, a powerful organization known as the Mirage Mirror Syndicate rises. They begin collecting ancient relics and artifacts scattered across the fused worlds, aiming to reshape reality into a controlled dystopian version of the multiverse under their rule.

However, not everything falls under their control. Nine humans refuse to accept this future. Standing against the Syndicate's vision, they become the last resistance-fighting across broken realities, forming alliances from different worlds, and challenging fate itself to prevent the complete domination of the multiverse.
