Honshin plot
While at work, Sakuya receives a phone call from his mother, who wants to talk to him about something important. When he goes home, Sakuya is seriously injured. After a year, he wakes up from a coma and everything is different: his mother has died and the factory where he worked has been closed due to robotization. Somewhat confused by the drastic changes in the world, he starts a job in the technology sector and acts as a lifelike avatar. Unable to cope with his mother's death, Sakuya turns to Msato Nozaki, hoping that the developer can recreate his mother with technology.
