In the year 2020,
the world was on the brink of collapse,
steadily accelerating toward catastrophe.

Humanity had broken its covenant
with God and began shifting between
The virtual world and the real world.
The boundary between them had become

unclear, and "particle duality" started to
reshape the world
with tremendous power, causing compound
nuclear fission.
This led to the creation of the

"Parallel Universe"—a complete "dual world"
that had never existed before.


In this world, those with special powers

could manipulate reality, creating second

and third copies of themselves. Fear,

uncertainty, and deception spread like

wildfire. At the top of the system was an

android called "Moon Child," created by the

enormous computer "Clara," developed by

Paradyne Co. Moon Child, an AI-driven

being, had become the ruler, expelling and

slaughtering humans in an endless cycle.

Androids followed the humans,
while the humans

desperately tried to flee.


Seeing this chaos, scientist Nicola

began developing an AI android called

"Full Metal Rabbit" to save humanity.
The world's best scientists gathered together,
working tirelessly day

and night for two years in an industrial waste

disposal facility located 1 kilometer
underground in an abandoned mine to
hide from Paradyne.


Finally, in the year 2033,
Full Metal Rabbit "KOSMO"

was born. This last hope for humanity was a

tender-hearted super AI android. Though its

appearance resembled a simple rabbit with

scars covering its body, it was, in fact, the

"Super Rabbit"—an entity capable of

controlling all the information gathered

from human intelligence. It had attained

immortality and created energy by

absorbing nitrogen from the air. KOSMO's

mission was clear:

to save all of humanity.

The world is at peace.
