Kurotsuchi is a calm, lighthearted, and self-confident kunoichi who inherited not only the technique but also the boldness from her grandfather Oonoki. She likes to tease the old man, hinting that it's long past time for him to retire due to his bad back. At the same time, she is sincerely devoted to Iwagakure and does not hesitate to propose harsh solutions: for example, killing the Eight-Tails and Nine-Tails jinchuriki to simultaneously thwart Madara's plan and weaken Konoha and Kumogakure. This pragmatism borders on cynicism, but she is not devoid of a sense of camaraderie: when Akatsuchi is wounded, she is ready to take revenge despite their constant squabbles. Kurotsuchi is confident in her abilities, which sometimes turns into arrogance, as in her skirmish with Kabuto, where she fell into a trap after underestimating her opponent. In battle she is cold-blooded, calculating, and knows how to deceive — for instance, she transforms into Sasuke Uchiha to lure Deidara out of hiding. Despite her outward maturity, she has a hidden childish side: she secretly enjoys flying on the turtle Genbu, but strictly scolds Akatsuchi for his enthusiasm.
