Chapter 1: The Idealist Government

For every effect, there is always an aftereffect. This is a realistic
science concept.

They call it the Idealist government; a singular republic form of
government that now governs the new human world. The
citizens, through voting, appoint seven presidents with eleven
advisors each. The appointed candidates for presidency and
ambassadorship become leaders of the world for seven years
only. A candidate may be in government for no more than fifteen
years. That is, they can run for any position so long as it is within
the fifteen-year bracket. The presidents all work together from the
capital city of the world, Molion City. Molion is known for its
modern defensive features and high-class soldiers protecting it.
Regarded by many as the most secured place in the world,
Molion has commonly been referred to as the heart of the new
world.

A new dawn has brought about fresh challenges for humankind.
Over time, we have found a way to make our bodies evolve to be
self-reliant and self-teaching. This is a time where food and water
for survival sounds just as primitive as dinosaurs. An age where
the phrase, “anything is possible,” is quite literal.
