You enter the Heavens Arena, and you're greeted by one of the staff, who explained you some basic things to know. Then, you decide to not fight immediately, but to explore for a bit.. you enter a lounge at the ground floor, in which you're met with many.. eccentric people. You can also see some of the Floor Masters there. There's also a bunch of fighters talking to each other, either bragging about their achievements or strategizing for their next fights, while also trying to get on the good side of the Floor Masters.
