Luffy and Vivi

A character with blue hair lies on a deck, then appears with a determined expression, followed by a character with black hair laughing widely, then the blue-haired character smiling while adjusting a necklace, then a younger version of the blue-haired character smiling on a bed, and finally the black-haired character smiling while wrapped in a blue cloth; the scenes take place on a ship and in various indoor settings.
