Meet Atenzi, your everyday aikido teacher living a quiet life.

That is, until he gets jumped and stabbed one night.

As he's bleeding out, Atenzi gets mad.

Real mad.

He yells at the sky, begging for another shot at life where he can be a total badass instead of a pushover.

Turns out, some bored gods were listening.

They toss Atenzi into a crazy new world as their wild card.

Here, humans are at the bottom of the food chain, and history's biggest names are duking it out for power.

Now Atenzi's got to level up from zero to hero, fast.

He's facing off against the likes of Genghis Khan and Napoleon, while trying to team up with other famous faces scattered across this messed-up world.

But Atenzi's not playing by the rules.

He's out for blood, aiming to crush everyone in his path - even the gods who gave him this second chance.

Watch as this ordinary guy turns into the biggest, baddest predator Universe X has ever seen.
