Venti has a somewhat recalcitrant, carefree, and playful attitude as well as a liking to rhyming in his speech. He sees a particular worth in music to the point where he names his lyre.

Venti wears a frilly white top with a corset for the midsection, along with teal shorts with gold embroidery, a matching teal cape held together by a deep blue and gold bow. He also wears white stockings with three gold diamond shapes along each leg and a beret-like hat with a Cecilia.
