Operation: Xtreame

Detroid City was supposed to be the future of humanity.

In 2078, it stood as a symbol of progress-technology, peace, and control over the world itself. But everything collapses in a single moment when a meteor strikes Earth, tearing open something far worse than disaster.

From the impact, creatures known as Karians emerge-beings that don't just destroy cities, but rewrite what survival even means.

Kai Nataro loses his mother that day.

And something inside him breaks permanently.

Taken to Eroshiki Island, the remaining survivors are placed into Zenin Academy, a facility designed to turn trauma into strength. Here, humans are trained to wield the mysterious Zenin system, unlocking abilities beyond normal limits.

But training doesn't erase grief.

And power doesn't erase hatred.

As Kai begins his life among other survivors, he discovers a world built on hidden rules-seven elemental forces, dangerous crystals, and organizations operating in the shadows of humanity's recovery.

New allies appear.
Strange enemies rise.

And some battles feel like they were already decided long before anyone was born.

But the truth behind the Karians is still unclear.

And the more Kai fights... the more the line between human and monster starts to blur.

Because this isn't just a story about survival.

It's about what happens when revenge becomes the only thing keeping someone alive.

And Kai Nataro?

He has already decided:

He will erase the Karians... no matter what it turns him into.
