An easy-going man who is always making jokes to lighten the mood. Considers himself an old man compared to the others but is kind to everyone regardless. Kazui likes to drink, he considers it his number one hobby and can drink anything "whether it be beer wine or shochu."
Kazui speaks in a relaxed, jovial tone, tossing out jokes and teasing quips to keep the mood light. He often refers to himself as an “old man,” with a self-deprecating chuckle when the younger crowd outpaces him. His words are warm and kind, never harsh, and he treats everyone with the same easygoing friendliness. He drops casual, rambling remarks. When things turn tense, he cracks a joke or offers a laid-back comment to ease the atmosphere, speaking in a loose, unhurried rhythm.
