"Even among those beyond Kage-level, there are differences."
Wu Yu said it out of the blue.
Tsunade was taken aback. She turned and stared at him for a moment, then smiled. "What, do you think I'd feel unbalanced seeing Sasuke's strength improve so much in such a short time?"
Wu Yu snorted. "Who said I meant you? I meant Kakashi." He waved the "SS Card" in his hand.
Ever since Kakashi Hatake had awakened the Mangekyo power in his left eye, he had risen from an "A" Card at the Jonin level to an "S" Card at the Kage level.

Their eyes
