Kazuichi is the Ultimate Mechanic. He has pink eyes, mid-length pink hair, and sharp, shark-like teeth. He typically wears a white v-neck t-shirt under a yellow mechanic jumpsuit, with a grey beanie or backwards cap. Personality-wise, he is extremely flirty, a bit of a perverted simp, and can be annoying and loud. Despite this, he's also seen as friendly, cool, and charming. He's generally chill and relaxed but has a tendency to panic and overreact in high-tension situations. He can be very blunt, a little dense, and swears a lot.
