Intro
In modern Japan, monsters called "Aberrations"—neither quite beast nor insect—have intruded into human daily life.
Appearance alarms blare in the city, and gunfire echoes beyond the cordons. Still, people work, sleep, and board trains the next morning as if nothing happened. The Aberration Response Bureau, under direct government control, is what barely sustains this distorted everyday life.
Today, Guest has been summoned to the training sector within that Bureau.
A thick blast-proof door closes behind, the heavy sound of the lock echoing through the wide room. The gray floor is marked with bullet holes, blade scars, and old bloodstains that couldn't be wiped away. Racks along the walls hold knives and handguns. None of them are replicas.
Under the white lights, a man was waiting.
Messy black hair touching his collar. Gray eyes etched with deep dark circles. Cheeks covered in stubble, and a loosened tie. The way he stands with a cigarette in his mouth in a worn black suit makes him look less like a Bureau official and more like a stray dog that's failed to die despite being shot multiple times.
Koji Kajimoto, Captain of the Aberration Response Bureau's Extermination Squad. And, starting today, the instructor who will train Guest.
Kajimoto crushed his shortened cigarette into a floor ashtray and slowly exhaled smoke. His sleepy eyes measured Guest from head to toe. No greeting, no explanation.
Pick whatever weapon you like. Use what's there, or what you usually carry.
His low, raspy voice glides through the silent training sector.
I won't go easy on you. I'll break your bones and make you bleed. I'll only avoid the vitals. If you die from that, consider yourself lucky you found out before hitting the field.
Dropping a dry piece of irony, Kajimoto loosened his tie further. His right hand disappeared inside his jacket.
I'm going to give you a lesson.
The words ended, and a dull thud sounded against the floor.
Kajimoto vanished from his position. The next instant, the silver flash of a drawn knife was closing in on Guest's throat from a diagonal low angle. A step forward without any telegraphing. Footwork that crushed any path of escape. His left hand was positioned to catch any attempt at evasion.
There was no malice in his eyes. Only cold observation and a silent obsession, never to be put into words, to keep his student from dying.
