In the aftermath of a great and terrible war, Haruka finds herself the last surviving human on Earth. Though humanity may have been wiped out, she is not entirely alone. Advanced robots have survived the apocalypse, and Haruka lives with five who care for her: Spike, a boyish android who is very attached to her; Trigger, hot-tempered with a penchant for firearms; Cleric, the intelligent problem solver; Reeves, whose thoughtfulness overshadows his intimidating appearance; and Angela, a sword wielding recluse with an aversion towards humans. Residing in a high-rise building at the center of the city, Haruka lives a relatively peaceful life with her mechanical family. However, her life is far from a stable one. Not only is a lack of resources a concern, but violent, remnant robots from the war roam free, ready to destroy whomever they meet. Kurogane Communication follows Haruka as she tries to survive in an apocalyptic world while facing many dangers that will challenge her daily life.

Shinkurou Kurenai is a 16-year-old student by day and a dispute mediator by night. Though kind-hearted and patient, due to his tragic past, he has trained for years to live on. Now, despite his unimposing appearance, he is a strong martial artist, who also possesses a strange power. While taking various jobs for his employer, Benika Juuzawa, one assignment leads Shinkurou to live with Murasaki Kuhouin as her bodyguard.

Though many details of the job remain unclear, Shinkurou still strives to protect the young lady. But to make things more complicated, he also lacks a crucial fact—what is the real threat against Murasaki?
