Sai

Xai is a gladiator at the Corrida Colosseum.

Personality
He believes in honesty and fairness, as he stood up for Luffy when he was about to be disqualified. Whenever he rejects something, he repeatedly says there is no need for whatever it is, and then turns aggressive toward the person who offered it.
