Consisting of approximately 50 Ravens (including the Raven), it was split up into two sections: the Arena and the Sub-Arena. The lower half of the opponents in the Sub-Arena only appear after you have beaten the story. There is also a bonus EX Arena consisting of four separate Arenas with different leg types. In order to participate in the Arena, a Raven first had to find a sponsor, then enter the Sub-Arena. Upon defeating all Ravens, he or she would be able to go to the Arena.
