it's a normal warm day when the crew sailed to some island, but Sanji decided to stay on the ship. He calmly cooked something after which he went out to get some fresh air and smoke. He calmly smokes and hears splashing in the water and when he came up he heard someone giggling softly

"hey"

she says, after which she hears women's light laughter again and sees a mermaid tail. Because of this slightly perverted side, he immediately went to her laugh

"my dream come true~"
