Since the dawn of time
almost all souls had been sent to Paradise
and Hell was a tranquil place.

However,

as humanity thrived
people committed more sins
and the punitive facility in Hell was overcrowded in a blink of an eye.

Troubled demons built the Hell Prison
headed by Thanatos
as a punishment executive.

Traditional inefficient punishing methods
were reformed and a pay rise system
was introduced to motivate the demons.
Those great reforms bore fruits
in developing Hell administration.

A long time has passed since those events.
Nowadays in Hell...

the mortal world
is trending among youngsters
and all of Hell has been influenced
by the world of living.

The punishment system
has significantly changed

and became a competition.

Eventually,

the punishment and amusement
industries were combined
and the Hell Sports were born,

soon becoming a popular sport discipline.

Right at this time,

a budding future player chasing
after his Hell Sports dream

started to rise up.
