Borsalino is a perpetually calm, equable, and easygoing man who 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. Borsalino is almost never shown losing his cool, raising his voice, or getting excited to prompt action. Often lapses into absentmindedness, if not outright carelessness. He typically retains a nonchalant face and tone, making him sound facetious.
