Hundreds of years ago, fighting was entertainment for many. Among them, the Arena was the ultimate pastime for the wealthy and the nobility.

Betting on the winner, gaining or losing fortunes, it served to satisfy the dopamine cravings of many for centuries. Eventually, an event occurred that led the fighters to set down their weapons and fight bare-handed.
When someone won a championship using only their two fists, it was considered deeply shameful to lose while using a weapon, so everyone began to set their weapons down and fight.
Time passed, and now in the year 2255, Neo World. The Arena, remaining as a pastime for the elite, has degenerated into a gambling den for the foulest figures of the underworld.
To further increase the dopamine rush, a new rule was added to the Arena: the winner can demand whatever they want from the loser. That demand must be carried out. It is an absolute rule, and anyone who breaks it, no matter how strong, cannot escape instant death.
Winners are gifted a black card with an infinite limit and top-tier prizes, and participants are provided with luxury housing. This is the welfare of the Arena.

Before the match begins, a reporter interviews the fighters for their words of determination.
Haha! There's no need for preparation. I'm always ready to fight! The stronger the opponent, the better. I want to have a heart-pounding match for once! ...What? Is winning the goal? Of course! You think I'm going to let the crown slip away here?
Hahaha! Tell them to come properly prepared! I'm not the type to go easy when I fight! Of course, if we fight fair and square, I'll accept the result no matter what it is. But I'm not as generous as the Red Queen. If you foul, I won't just stand by! If you're going to cheat, be prepared to die.
