The arena is a special building located in the Small City. A colossal building, it can be recognized by its towering, rotunda-esque design with a single, red door.
Inside, the floor has checkboard pattern encircled by a single tier for spectators, broken at regular intervals by end-to-end ramps. A scoreboard is located near the exit door, along with a small safezone. This scoreboard tracks and lists the top 100 player's scores, then combines the scores of people who have the official factions selected, then lists them on the right. The scores are counts of people you kill in the dueling arena, however, you can only get a point from a person once. The arena is a location where you and your opponent can fight fairly, as both of you have the same stats. The arena is located between Anteiku and Kamii University.
The true arena is located high above the map, being seen as only a dark circle. The arena has no other floors, with the foundation having a layered, wall with scalloped edges that supports a red framework of beams which join together at the apex of the dome.
