The 3 most proposed actions as well as two propositions made only once are submitted to the majority vote.Rules and systems have been set to ensure the dynamism of that community, and to prevent identification of people and places where the android evolves in modern-day Japan. And so the Dēmokratía android came to life.

Astro Boy

In the 21st century, robots are commonplace and in many cases, have replaced human beings in the workplace and in other roles. Dr. Tenma used to be the jovial head of the Institute of Science; but once his son Tobio was killed in a tragic accident, he turned his attention to building a robot to replace his loved one. Named Astro Boy, Tobio's replacement was intelligent and thoughtful; yet he didn't age, and ultimately Dr. Tenma resented his creation and sold him to a cruel circus manager. Luckily for Astro, he was soon liberated by the current head of the Institute of Science and given a new life. In addition to learning how to become a better "person," Astro uses his nerves of steel and superhuman strength to put a stop to evildoers and withhold justice for all!
