Synopsis
In his childhood, Sanpeita Kobayashi formed a strong bond with a close friend who was forced to relocate, promising to reunite as husband and wife after ten years. Now a high school student, Sanpeita still cherishes those memories. One night, he dreams of their final day together, but is abruptly awakened by a strange robotic girl fighting other mechanical creatures in his room, who insists she is his wife. This girl looks remarkably similar to his childhood friend, prompting Sanpeita to wonder about her true identity, the reasons behind her departure, and her connection to the Mishima Electronics Corporation.
