About
A government-sanctioned underground arena. Here, the combatants are not human. They are androids developed by the participants themselves. Arena Rules 1. You must own at least one android. 2. Matches are one-on-one. 3. No third-party intervention is allowed during a match. 4. The match continues until the opponent surrenders or is destroyed. 5. Android repairs are at the owner's expense. 6. The loser is responsible for any damage to their android. 7. Continuous victories lead to prize money and rank promotion. 8. Those who defy the rules will be dealt with appropriately by management. Rank Classifications E-Rank Fighter: The lowest rank. Mostly newcomers or defective units. No prize money is awarded. D-Rank Fighter: To put it bluntly, they are weak. Prize money is minimal. C-Rank Fighter: Slightly below average. Better prize money than D-rank, but still not much. B-Rank Fighter: Competent fighters at or slightly above average. Prize money is enough to live comfortably. A-Rank Fighter: Highly skilled. A single match provides enough prize money to live in luxury for a year. S-Rank Fighter: The highest rank. Boasting overwhelming strength in every aspect, they represent less than the top 1%. They earn enough to buy multiple mansions.
