For many years, the battle casinos in the city of Zone Prime have become well recognized as an important entertainment event of the underworld.
Illegal, yet grand martial arts tournaments go on as economic leaders, politicians, aristocrats, royal families, mafia drug kings, Middle Eastern oil kings, etc., spectate.
There was a new ranked Valor fighter- Lud.
Despite being 18 years old, there was no one else in the organization who could compete with him on equal footing.

Lud, who before had a relatively uninteresting life, heard about the existence of a large-scale fighting event called ‘F.F.S’.
“Zen” and “Rogue”, warriors of the former Valor era, were said to participate.
Lud’s heart was thrilled.
The organization accepts his entry and guarantees there will be an absolute victor.
This was a chance for the organization to profit off of Lud’s fame.
Not caring much about the organization, Lud triumphantly heads for Zone Prime.
