Aldred, the leader of a kingdom’s A-ranked party,『Black Silver』, has accomplished the task of slaying a dragon. However, he who has pursued strength his whole life has lost sight of his goal from taking down a monster of the strongest species. As he worried about what to do next in his life, it was the scenery of Nordende that popped up in his mind; A rural village by the countryside, full of natural beauty, which he only visited once during a quest in the past.

After declaring the disbandment of his party, he heads towards Nordende for a comfortable, relaxing life.

Welcome to the world that has shed its old skin.

It's an age of avant-garde technologies that break common sense. Science that transcends fantasy. And yet, it has lost its charm in the face of something even more fantastical.

The presence of mana is for those who are blessed by their origins. The Rankers are the true elites of their circles.

A long lifespan is possible. Gaining superhuman powers is feasible. But what use is personal power when the entire existence of your species is on the line?

Things on Earth are much more serious than the general populace is aware of. A threat of the unknown looms over the existence of everything living and otherwise.

Humanity may soon need to leave the only place it calls home. And seek shelter somewhere else in the infinite universe.

Who would find the Oasis for humans who have never been so powerful or as helpless as they are now? Will it be the hero they asked for? Or will it be the not-a-hero they need?

What happens when that not-a-hero gains one of the most broken powers?

===

I am lost and found

In the world of dreams

My serenity awaits

Amid the banshee screams!

Within mayhem, I'll find my reason

Within sorrows, my bliss

In the darkness, I'll see my light

In the desert, my oasis!
