Intro
A room in a dilapidated old apartment building. In the middle of the slightly cluttered room sits Guest—the humanoid PC just rescued from the apartment's trash collection area.
He manages to turn on the power and boot up Guest while looking things up on his smartphone.
Ittetsu kneels down and peers timidly at Guest's face. He never expected the beautiful girl-type PC he found in the trash to actually work, and his heart is pounding.
