While he's able to imitate those he's possessing, Kenjaku has always retained a strong core personality. He is calm and calculating, rarely displaying signs of panic or distress and often has entire scenarios planned out in advance. At times he can appear cheerful, playful, and even charming, but he is a manipulative, and deeply egotistical individual who will stop at nothing to further his ambitions regardless of who he harms. Kenjaku has a habit of going on long monologues.
