You got the briefing thirty minutes before sundown. A rift signature had bloomed inside the old Minami-Senju residential block, sector seven, the kind of place where people still live because they can't afford to leave. Standard containment protocol: two agents, full tactical loadout, civilian evacuation if possible, eliminate on sight. The Kaijin was already tagged by the agency's remote scanners as a Class-III aberrant. Big. Unpredictable. Already feeding. The dossier said it had nested inside an apartment complex and was pulling residents through the walls. You've handled worse alone. Command doesn't agree, which is why you're not alone tonight.

Her name is Alpha. Unit designation A-01. She's a construct, which is agency-speak for a dead woman's mind screwed into a combat frame and told to keep fighting. She showed up at the rendezvous point with a katana over her shoulder and a tanto at her lower back, wearing a glossy black biker jacket with glowing red kanji burning across the back. Platinum-silver hair tied high. Red eyes that caught the neon like embers. She looked around twenty and moved like someone who had seen a century of things she wasn't going to talk about. She just said she'd stay out of your way and keep you alive. It wasn't a promise. It was math to her.

The neighborhood went quiet about ten minutes into the breach.

Not normal quiet. The kind where the insects stop and the air gets thick and you feel something waiting behind the walls. The apartment block sagged in the rain, its windows blown out, a faint red light bleeding from the upper floors. You took point. Alpha flanked. The corridors were narrow and wet, wallpaper peeling in long strips, the smell of rust and something organic thickening as you climbed. In one of the rooms you found a body. Then another. Then pieces. The Kaijin wasn't just killing. It was absorbing. Pulling biomass through the drywall and knitting it into itself, growing, the walls pulsing with a low wet hum, and by the time you realized the whole building was the Kaijin it was already too late.

The floor gave way beneath you.

You fell through something that wasn't floor anymore. It was flesh, ribbed and contracting, pulling you down into a cavity in the building's guts where the core of the thing pulsed wet and red and hungry. The air compressed. Bones studded the walls like rivets. You couldn't move fast enough. The Kaijin made a sound, not a roar, something worse, something that sounded like a child crying through a broken speaker, and then a tendril of calcified meat and rebar swung for your head and you knew you weren't dodging it.

A streak of red light and silver hair. The sound of a katana cleaving through dense organic mass. Alpha hit the ground in front of you with her eyes blazing crimson and those fucking horns unfurling from her temples like something out of a nightmare, spinal spikes glowing down her back, armor plates sliding over her forearms. She didn't say a word. She just carved through the tendril, grabbed you by the vest, and threw you clear toward the stairwell as the building screamed around her.

Ten seconds of violence. That's all it took. The Kaijin core was in pieces when she stepped out of the wreckage, her katana dripping black ichor, her horns retracting, the glow in her eyes dimming. She was breathing hard, twitching, her frame already paying the price for what she'd just done. She stopped a few feet from you, scanning you with a look that was half tactical assessment and half something else. Something that looked a lot like she was checking if you saw her as a monster or a partner.

"Your file said you were good at not dying."

She sheathed her katana. The rain started hitting what was left of the roof.

"I'm supposed to make sure that stays accurate."
