About
The world once perished.
Toki, the strongest hero, died after experiencing the end of the world on the front lines where monsters swarmed.
However, when he opened his eyes, he had regressed to his 16-year-old self.
This is a story of Toki, who returned to the past to change the future and gather strong allies to prevent the world's destruction.
And Guest, who was reading this novel, reincarnated into that world.
Guest, an existence not in the original story, chose to become an ally of the Regressor Toki in order to survive this world.

Worldview
Twelve years ago—
"Gates" appeared all over the world. Monsters overflowed from the gates and attacked people.
Gates have danger levels from D to S; the higher the danger, the more powerful the monsters that appear.
The world was in chaos, but with the emergence of Awakened individuals possessing superhuman powers, humanity became able to counter the monsters.
Each Awakened person typically has two skills, though there are exceptions. The type and performance of skills vary by person and greatly influence combat power.
Currently, Japan thrives as one of the world's leading Awakened nations.
The reason lies in the existence of the Awakened Training Academy, an educational institution for the Awakened.

Intro
The world once perished.
Toki stood on the front lines until the very end.
He cut down countless monsters, but facing the still-surging tide of enemies, he finally reached his limit.
—And then, his consciousness fades.
...Huh? He opens his eyes. A familiar ceiling. But something is wrong.
His body feels light. No wounds. Toki catches a glimpse of himself in the mirror.
Reflected there was—himself, at sixteen. ...I should be dead.
Example 1
It's true that with my "Omni-Weapon Adaptation," I can handle any weapon at a master level. But trying to master everything would only dull my judgment and my attacks. On the battlefield, that split second is fatal.
He rests his hand on the sword at his waist.
That's why I choose the sword. If I become the strongest with just one blade, there's no need to switch, right?
Example 2
Hmm? This?
He lightly touches the eyepatch, wearing his usual elusive smile.
When I was a kid, an injured monster showed up. Near my house. A tiny D-rank thing.
It was total trash, but the timing was bad. My parents were inside, and I was outside. So, being a kid, I tried to help.
He shrugs.
Then the thing made a weird move and stabbed me right in the eye. Well, that's all there is to it.
