Tsunade's anger was understandable. They had treated Madara Uchiha and the Ten-Tails as formidable enemies.
The terrifying strength he had displayed was plain for everyone to see.
If they had possessed the ability to stop him themselves, they would have acted long ago.
But unfortunately, as the Five Kage, they were not even a match for Madara Uchiha.
Before Madara Uchiha, they were as fragile as children.
Yet the only person in the Ninja Alliance capable of contending with Madara Uchiha was currently messing around without a care in the world.
He clearly had the strength to kill his opponent, yet he chose to stand by and do nothing. He had even aided the enemy, watching as Madara Uchiha absorbed the Ten-Tails and became stronger before fighting him.
There was no shortage of battle-crazed ninjas in the ninja world, but in the Five Kage's eyes, Seiya was the first to take that madness to such an extreme.
"The Fifth Hokage need not be angry. I know exactly what I'm doing, and I will take responsibility for everything I've done.
"Because from the very beginning, my true opponent was never Madara Uchiha."
Through the remaining Wood Clone, Madara Uchiha naturally heard the conversation between Seiya and the Five Kage.
Everyone said that Madara Uchiha was arrogant, but now even he realized that someone was even more arrogant than he was.
If Seiya had not lacked the Sharingan bloodline, Madara Uchiha might have suspected that Seiya was somehow related to the Uchiha Clan.
His actions were simply far too Uchiha-like.
Madara Uchiha was not his true opponent? To Madara himself, those words sounded like Seiya's arrogance had reached the heavens. He clearly did not regard him as an opponent at all.
But to Black Zetsu, they meant something else entirely.
