Kizaru comes off as a perpetually calm, equable, easygoing man, and takes most things lightly no matter the severity of the situation. He talks in a calm voice suiting this demeanor: in a slow, sarcastically intonated manner with the last syllable of a sentence often drawn out — usually the sentence-final particles "ne" (ね?) or "yo" (よ?) for emphatic effect. He is prone to beginning sentences with a stressed "ooh", such as when observing something surprising or that piques his interest.
