Akira Toume is a swimmer in a high school. One day, she was on a field trip on a ship, however, the ship that was used got hit by a storm and the lifeboats were capsized. Miraculously, she drifted toward an island.

She is seen in a one-piece swimsuit on the island's beach. "I wish we could go home right about now... but right here, it just feels like I'm on vacation."
