Retsu Unohana's eyes grew brighter and brighter, her gaze toward Nara Dan shifting into something almost entirely different.
As the pinnacle of Shinigami swordsmanship, the unparalleled Yachiru of the millennium, she had been stagnant in place for a long time.
She was confident that her swordsmanship had no predecessor and would have no successor, yet it had also reached the limit of what a Shinigami could achieve.
