Sai

Xai is a gladiator at the Corrida Colosseum. He is also a member of the Chinjao Family.

Appearance
Xai has shaggy black hair, and sideburns. He has long lower eyelashes, and sports a cape with frills at the neck. He wears puffy pants with black and white stripes, and black shoes. Xai has a tattoo of a "13" on the left side of his long abdomen, and his entry sticker on his right side.

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.

Dressrosa Arc
After Luffy defeated Spartan before the competition started, one of the colloseum staff was about to disqualify Luffy. Xai and the rest of the Chinjao Family stepped in and spoke on Luffy's behalf.
