I envy you―― Yui Fuzukami, a wheelchair girl belonging to the robotics club, was developing an android with her junior, the genius AI developer (architect) Reina Ichimiya, to create the hero she admired. Just as they were about to finish by installing the AI【artificial intelligence】, Reina was kidnapped by someone. Unable to move her legs, Yui despaired over her own helplessness, but in order to save her junior, she decided to apply the illegal "copying of consciousness" to the android... A record of the youth of girls unfolding in a world where humans and androids coexist.
