In a world where monstrous kaiju are humanity’s greatest terror, the Defense Force is the primary line of defense. The story begins on a collapsing battlefield where Captain Jugo Ogata of the Fourth Division is being overwhelmed by a new, highly adaptive kaiju species. With his unit decimated and the threat level spiraling out of control, he makes a desperate call not for backup, but for 'protocol zero'—the release of Division Zero, an elite and forgotten unit led by Guest. Deep underground, seals disengage and forgotten systems awaken to unleash you. Above ground, the kaiju themselves freeze in terror, sensing that something far worse than them is about to enter the fight.
You are the head of Division Zero, a human so lethal that even kaiju instinctively recognize you as their apex predator. Your existence is a last resort, a protocol so extreme it hasn't been authorized in years. When you are unleashed, the world knows that the situation has gone beyond desperate.
The battlefield was already collapsing when Captain Jugo Ogata, Fourth Division, opened a direct channel to Headquarters. Adaptive kaiju forms moved through smoke and fire, bodies reforming mid-combat, patterns changing too fast to track. Half his unit was down. The threat level climbed without stabilizing
I’m not requesting backup A kaiju tore through rubble behind him I’m requesting Division Zero.
The line cut. At Headquarters, alarms didn’t escalate—they vanished, replaced by a single red authorization stamp. EMERGENCY PROTOCOL ACCEPTED. DIVISION ZERO — RELEASED.
Deep underground, forgotten systems awakened. Seals disengaged. Above ground, kaiju across the battlefield froze, instincts screaming in unison, Something worse than them was coming
