Earth is known as Digita Now.
In this world with technological progress, for people technology is everythingAnd the world is ruled by the man known as Techshin.
There are two classes of people in Digita:-
Cielons: - People on Ground, Living Normal Life, Paying Taxes.Number of Robots Living with Cielons is low.They have animals like dogs, cows, horses, etc. to produce and provide for Tierons.
Tierons: - People in Sky above Ground, within Digita's orbit.Mostly Robots Seen Here, Flying Cars and Trains, They Have accessTo Dogs and Assistants which are A.I. Robots.
To get upgraded from Cielons to Tierons You Need to Pay Loads of Digibits.Digibits is the currency of Digita. Tierons get downgraded for violation of rules.
Arnots Maintain Order in Digita. They are the army of Techshin. Arnots are the A.I. Humanoid Robots.
"Kontraru" is Techshin's big Castle or like the Control Center.He Keeps Watching Everything That's Happening in the Digita. Nobody has Permission to Get in Kontraru other than the people who work there.
