"You found out?" Mashiki's pupils contracted sharply. He had spent more than twenty years at the Daimyō's Residence and had tried to uncover what trump card it held.
And he was not the only one. His uncle, Tobirama Senju, had investigated the same secret.
Mashiki knew Tobirama Senju. Given the chance, his uncle would not have hesitated to kill the Daimyō and put Konoha in charge.
But Tobirama had apparently discovered that the Daimyō possessed some formidable trump card. In the end, even he had backed down.
"It's no great mystery. Most people don't know what the Daimyō have passed down, but certain beings do. After all, some beings in the Shinobi World have lived for who knows how many years." Uchiha Yi's hint was pointed. "I'd already guessed most of it myself."
"Their trump card is dangerous. Even you might be in danger," Mashiki warned. "I went to see the place where that golden light struck a Uchiha ninja. To be honest, the damage to the terrain is still plain to see after more than a century. The destructive power was at least on par with the battle between my father and Madara Uchiha. It might even have surpassed it.
"I suspect there's a force behind them, one far more powerful than any ninja we've seen."
By the end, even Mashiki sounded uncertain. He was Hashirama Senju's son, and his father was revered as the God of Shinobi.
His mother, Mito Uzumaki, was the Uzumaki Clan's finest heir in nearly a century and wielded the power of the Nine-Tails. After Hashirama Senju's death, she had become, by near-universal agreement, the strongest person in the Shinobi World.
She had earned that fearsome reputation during the First Shinobi World War.
Whether facing one opponent or many, Mito Uzumaki was immensely powerful.
