Going Against The Tide

The duo originally didn't have any plans with battling anyone in the Seventh stage. Their plan was to challenge those in the Eighth stage after getting to the top four spots in the Seventh stage of the Sovereign Plane without having to compete. No one would dare to challenge them as long as they were there. They've beaten everyone who had come to challenge them since they got to the peak of the Seventh stage, hence the reason no one wanted to challenge them while Grey was still watching. Now that there was no one watching, and Grey, the only person who could threaten them, was battling them, they had no choice but to try to see if they could win, which meant using some of their hidden techniques. 

One of them had already used a secret technique to improve his strength, and when he thought he had killed Grey, Grey phased through the attack. Not just that, but Grey struck him in the end. 

Bang!
