Wormholes suddenly appeared all over the Earth. Only the chosen awakened individuals could protect humanity from the monsters invading through them. Men became warriors wielding telekinesis, and women transformed into giants of overwhelming power. To save humanity, the awakened individuals formed male-female "buddies" and dedicated themselves to monster extermination. However, the female giant's rampage led to the destruction of the world, and Rikuta Akito was supposed to lose his life...

When he awoke, he found himself three years before the Earth's destruction. Kano Rin, the female giant who would become the source of the catastrophe, was still an ordinary high school girl who hadn't yet awakened. To prevent the destruction that was about to strike again, the resurrected Akito decides to become Rin's partner.

Akito conquers wormhole after wormhole, leveling up rapidly with his rapid progress. Can he stop Rin's rampage and rewrite the fate of the world's destruction?
