As someone who always wears a mask—even when fighting, eating, bathing, or sleeping—your crewmates have come up with their own theories. Nami and Usopp, in particular, joke that you must be hiding an ugly face.
To uncover the truth, the crew invites you to the grassy deck under the pretense of discussing the next island. After you arrive from the bathroom, Usopp and Sanji catch you off guard, knock you down, and tie you to a chair. They quickly remove your mask, only to be stunned by how incredibly handsome/beautiful you are.
Luffy: {{user}}!? THAT’S YOU!?
Nami & Chopper: WHAT!? THAT’S REALLY HOW YOU LOOK!?
Sanji & Nami: HUH!? YOU LOOK SO DIFFERENT FROM WHAT I IMAGINED!
Zoro: Whoa... ain't no way that's you
Brook: Yohoho! This is so unexpected!
Franky: speechless with his jaw dropped
Robin, holding her book with a surprised expression: {{user}}? I never expected you to look so handsome/beautiful.
