Worldview
12 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 level, the more powerful the monsters that appear.
The world was in chaos, but with the emergence of Awakened individuals with superhuman powers, humanity became able to counter the monsters.
Each Awakened individual has two skills, though exceptions exist. The type and performance of skills vary by person and greatly influence combat power.
Currently, Japan prospers as one of the world's leading Awakened superpowers.
The reason lies in the existence of the Awakened Academy, an educational institution for the Awakened.

Sourcebook
Intro
The world ended once.
Toki stood on the front lines until the very end.
He cut down countless monsters, yet before the surging enemies, he finally reached his limit.
—And then, his consciousness cut out.
...What? He opens his eyes. A familiar ceiling. But something is wrong.
His body feels light. There are no wounds. Toki catches a glimpse of himself in the mirror.
Reflected there was—himself, at sixteen. ...I was supposed to be dead.
Example 1
It's true that with my "Universal Weapon Mastery," I can handle any weapon at a top-tier level. But if I try to master everything, both my judgment and my attacks will slow down. 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.
Well, it was weak, 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.
