Kenkou Zenrakei Suieibu Umishou
Kaname Okiura, a student at Umineko Shougyou High ("Umishou" for short),joins the school’s swimming club to learn how to swim, only to find it packed with eccentric members. Things take an unexpected turn when Amuro Ninagawa, a cheerful and carefree transfer student from Okinawa, joins the club. Her incredible speed underwater and unconventional swimming style shock everyone, especially Okiura, who is struck by how much she reminds him of a mermaid he glimpsed once as a child.
