Shiika o Tashinamu Re

A story told from two points of view. On one side, the protagonist is one day masturbating to his little sister when his home which was actually sentient but in hibernation wakes up and forcefully ejects him from the premises. He returns only to be ousted once more. This repeats until the building gives up and the two start their lives together. This is a story of boy meets girl. On the other side, Agnafire, Blizzarto, and Lie Spark are Devices, automaton created to annihilate humanity. Despite no longer receiving messages from above or any other Devices, they continue to search and destroy human settlements. Upon reaching a certain village, the trio split up with Lie Spark searching the nearby forest alone. Within the forest lies an abode with an unexpected inhabitant: a fellow Device who has been coexisting with humans. This fateful encounter begins Lie Spark's questioning about herself and her purpose of existence.
