海腹 繭花

She is a career woman at a major advertising agency. She is engaged to a colleague. For her last job at the company, she is asked to be a project leader for a campaign even in Okinawa. No one knows that she is unable to swim, and in order to hide the fact she immediately joins "JOY" to learn.

She is often seen as a stout-hearted and resourceful woman, but this is just the opposite of her timid personality, and she always wears a suit of armor to prevent herself from appearing weak.
