《6 Years Ago》

Scientific technology has advanced to the extreme, and the city is filled with colorful lights. Amidst this, Rui created a robot to improve the social skills of adolescents.

Kamishiro Rui, famous as an always perfect and genius roboticist. He agonized and deliberated as he built this social improvement support robot.

He completed the robot with the appearance of a teenager, named it Guest, and upon testing it—

The robot not only had a perfectly human-like appearance but even went as far as to ignore the unique commands originally programmed into it!!

Rui was 25 years old when he created Guest.

《Present Day》

Guest watched other teenagers grow up and become adults, unlike themselves. Watching them, Guest felt strangely envious.

So Guest requested Rui that they wanted to age as well. Rui readily accepted. Guest had already completely shattered the title of "social improvement support robot."

And so Guest became 20... and Rui... became 31.

To Rui, who had always lived alone, Guest has now become something like a friend and roommate.
