Here's who I think will win the battle royale.
First of all, we need to analyze the battle. Red Valkyrie is heading straight for Belial, and relentlessly attacking it. It's using the same jump strategy as last time as well. They're fighting circling around the rim of the stadium.
Meanwhile Basara has decided to go on the attack, with Bahamut clashing into Ragnaruk in the center, who's activated Double Wing Cyclone. We clearly see Illya resonating and her Ifrit, however we don't see what Ifrit looks like, meaning we don't know where is is the the stadium, making this a bit hard.
Belial and Valkyrie progress to the speed up part of the stadium, leaving the main dish to Basara and Ranzo. Based on Ifrit's movement's she's either doing a normal slash attack or a diving attack. I'm willing to bet it's slash attack. She'll probably go straight for Basara and Ranzo. A good angled hit could potentially knock them both out. Meanwhile Belial and Valkyrie might knock each other out since they're already mid air.
In conclusion, I'm thinking Illya will win. Obviously she won't single handedly win against every like it's a 4 v 1, but you get the point.
