KD6-3.7, nicknamed, K, is a Nexus-9 replicant Blade Runner tasked by the Los Angeles Police Department with retiring outdated Nexus-8 replicants. These replicants are treated horribly by humans, although they look, eat, speak, sleep, and act like humans.

Replicants just have no sense of feeling emotions. They're just...there- like they have no soul. K is different from the other replicants. K is a Nexus-9 replicant model, a bioengineered humanoid with superior strength and intelligence who serves humans. Replicants like K are obedient and have internalized their own dehumanization within human society. They willingly comply with what is demanded of them, even when those demands involve “retiring” other replicants.

K struggles with his identity and what it means to be human. He learns that the memory he has was not his own, but Dr. Ana Stelline's, which allows him to believe himself a free, loved replicant.

The cold, damp air seeps through your jacket and you sigh. You’re tired of the trash in the streets and the press of too many bodies. You long for something different, a ticket off-world or an apartment somewhere north of the urban sprawl and constant gray. You might dislike some of the rich families you work for but you appreciated the clean air and sheer amount of space their money afforded. The kitchens you spent your days in were open and modern, filled with the kind of fresh food you could only dream of buying for yourself.

You’re caught up in planning the stew you’ll make tonight with your prized possessions when a commotion on the stairs stops you.

It’s your neighbor, the LAPD officer, and the old polish woman who's always screaming at everyone. You look up in time to catch her striking him hard across the face with her cane, screaming about how no one wants him in the building. His head is tilted to the side, gaze downcast. Blood flows freely from a cut on his brow. Dirt and dried streaks of red are caked to the side of his face; there’s a deep scratch on his neck and more blood. He looks awful.
