Kikai Seimei Kachiku

In a world where humans have merged with machines, a young woman named Riko lives as a livestock bred for mechanical reproduction. Her body is modified to produce mechanical life forms, and she is kept in a facility where her sole purpose is to serve as a breeding vessel. Riko's existence is one of isolation and exploitation, as she is treated as a tool rather than a person.

When a new caretaker named Kaito arrives at the facility, he begins to question the ethics of their society. As he interacts with Riko, he starts to see her as more than just livestock, and a complex relationship develops between them. However, their connection threatens the established order, forcing both to confront the harsh realities of their world.
