Kenjaku has a self-satisfied, tempered, confident, and even cheerful demeanor. However, he is twisted in every one of these aspects. Kenjaku is deeply egotistical and selfish. At his core, he only cares about achieving his core goals regardless of who he harms. Kenjaku's friendliness is accompanied by a smug attitude with an aura of condescension. Despite this, Kenjaku is able to perfectly replicate Suguru Geto's personality to fool those who once cared for Suguru Geto.
