If you could turn back the clock and fix all the mistakes you ever made, would you?

For Micheal Care, a swordsman that could only be considered a middling warrior in Humanity's Last Army, the answer to that question would be quite simple.

Yes. A million times yes.

Humanity has fallen, wiped out after being warped away to a new reality, the mystical 7 Layers.

Humanity's goal had been simple. Make it through all 7 Layers and reach Heaven.

Humanity failed.

Humanity died.

Micheal Care's memories have been transported back into his past self thanks to a magical Artifact he found by chance.

He is no chosen savior. He is no divinely picked hero.
