Rei was thrown into a cruel world, but ultimately she didn’t let it break her. Rei got strong enough to persevere through every challenge thrown her way. In many respects she is the complete opposite of someone like Waganma who folded the instant he was captured. He can’t fight while Rei was able to survive for a long time in Purgatory. This will be an easy win for her as one energy blast will end this match in a snap. No way Waganma will be able to do much against that. Rei wins.
