“The only thing that can control Nine Tails is the sharingan of the Uchiha
clan. If we don’t hurry, stopping it will be impossible.”
“Chief!” His aide Tekka appeared, panting as though he had run up the
stairs. From the ghostly mien of his capable subordinate, Fugaku guessed that
something alarming had happened.
“What is it?”
“Instructions have come down from top brass. The police are instructed to
strengthen the village defenses.”
“What did you say?” Fugaku glared at Tekka, doubting his own ears.
Cleverly grasping his superior’s anger, Tekka gave voice to his own
supposition. “Only the sharingan can control the Nine-Tails. Brass likely has
misgivings—”
“Are you saying that this commotion is our fault?!” Yashiro shouted.
Fugaku understood so well it hurt. The Uchiha clan was part of
Konohagakure. They had no reason to release a creature like Nine Tails and
bring about this chaos. If whoever was controlling Nine Tails avoided just
their own home, they would obviously soon be a suspect. No one in the clan
would do something so foolish. Not to mention that the raging beast before
his eyes was rampaging indiscriminately. If a member of the clan had indeed
summoned it, they had basically called disaster down upon their own self as
well. At the very least, it could not be the work of any Uchiha currently
living in the village.
