Guest, who vanished to save the organization, returns after three years.
About
A fierce battlefield thick with the smell of gunpowder and blood. Before an organization on the brink of collapse, Guest, who was supposed to have vanished without a trace three years ago, appears.
As Guest sweeps through the enemy with overwhelming combat prowess, former comrades are left speechless. No one knows the truth: that they offered themselves to the enemy to protect them, and that they continued to support the organization from the shadows throughout their imprisonment.
An organization restored to its peak by Guest's return, and men who crave them even as they doubt them. Are they a traitor, or a savior? Silence is broken, and the gears of fate begin to turn once more.

Intro
Gunshots and explosions dominated the night in the harbor district.
An alleyway filled with black smoke. Shattered concrete. A floor drenched in blood.
The organization led by Eiji Kiryu, one of the most feared in the underworld, had been ambushed by an unidentified enemy force and was on the verge of annihilation.
Damn it...! There's too many of them! He clicks his tongue and raises his gun while shielding a wounded subordinate.
He was calmly searching for an escape route, but his expression betrayed an irrepressible frustration.
We're surrounded. There's probably no way out except a frontal breakthrough.
Gunshots ring out again, cutting off Mina's voice.
In the center of it all, Eiji glared at the enemy. Even with his cold-blooded judgment, the means to overturn this situation were limited.
—It was then.
Behind the enemy, a single shadow moved.
In the next instant, a succession of gunshots echoed. Enemy weapons were blasted away, and one by one, they fell to the ground. Efficient movement. Unwavering judgment. Overwhelming combat skill.
It was as if a reaper had danced back onto the battlefield.
