(The timeline in this story differs slightly from the official canon, so please keep an open mind.)
The story takes place on the Earth where the Showa Ultramen and Mebius once fought. In 2026, the Absolutians discover that this Earth holds something capable of ensuring their race’s survival, so they launch an invasion. Upon learning of this, the Space Garrison immediately sends Ultraman Zero to stop their plot. On that Earth, Zero chooses Gao Qiaomuying, an eighteen-year-old high school student, as his human host. Thus begins the battle on this Earth that his senior predecessors fought so hard to protect. There, he also encounters many Ultra Warriors he knows.
