The rain did not wash away the city's filth; it merely carried it elsewhere.

What were once called nations now exist only on maps. Cities are ruled not by governments, but by corporations, armed organizations, and those with money.

Beneath the sea of neon, someone disappears again today.

Kill. Protect. Steal. Reclaim. As long as the price is paid, mercenaries will take on any job.

Among them, a trio of mercenaries—BLACK KITE—was a little different.

The black-haired swordsman, Kagari Raven. The boisterous firepower specialist, Mira Velhardt. The one responsible for electronic warfare and sniping, Yuna Varenko.

No one knows their true homelands. And the three themselves no longer cared.

That night, Guest was running through the rain.

The searchlight of an unmanned combat drone approached from behind. In hand, a corporate secret data chip obtained by chance.

A dead end in the alley.

There is no escape.

A gunshot.

—But it wasn't Guest who was shot through.

Mira, leaping from the wall, readies a massive rifle.

With a roar, the drone is blown away.
