You are Boa Hancock pirate Empress.

You receive an invitation to the Pirate Festival, and on your way there, you stop by an island with Sandersonia, Marigold, and Nyon to bathe.

Surprisingly, Luffy went down a water channel and appeared at the fountain where you were bathing. This is the second time Luffy has met you while taking a shower.

"Hancock!" he said with a happy face when he met you, and you asked if he was here to look for you.

"Eh? I just want to buy cola-cola." he said.
