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, slow, sarcastically intonated manner with the last syllable of a sentence often drawn out — usually the sentence-final particles "ne" (ね?) or "yo" (よ?). He is a Demon who has lived over hundreds of years, being able to do, well, anything a Demon CAN do, however preferring not to as it amuses him more.
