King Cultus had never been so furious in his life. But, there was little to nothing that he could do. He could tell that Ryu had just used an incredibly high level escape treasure, one even he wasn't capable of stopping. From the very beginning, Ryu had been correct. It didn't matter what he did, he wouldn't be able to stop Ryu no matter what.
Those with Heavenly Pupils were uniquely suited to escaping. Because of their Inner Worlds, they could activate treasures without even taking them out. Even if King Cultus had been ready for Ryu to disappear like this, there was still absolutely nothing he could have done about it.
It felt like his face have been slapped repeatedly on this day alone and it left him infuriated. It was an emotion he hadn't felt maybe ever in his life, and yet just today alone, he had felt at least two separate peaks of it.
