Kenkō Zenrakei Suieibu Umishō

Plot

Within the Kanagawa prefecture lies the seaside city of Umineko. There, Kaname Okiura, a student in his 2nd year of high school, attends Umineko Shōgyō High School (海猫商業高等学校, Umineko Shōgyō Kōtō Gakkō, lit. Seacats Commerce High School), or Umisho for short. He is also the manager of the Umisho's swim team though he himself doesn't know how to swim. In fact, he is afraid of the water stemming from an incident which occurred some years ago. While he was at the beach, he had nearly drowned when a 'mermaid' pulled him under the water. He joined the school's swimming club in order to learn how to swim, but the club is filled with weirdos, who don't teach him swimming.

One day, a floating house arrives at the shores of Umisho bearing two persons. One of these is a cheerful, sunny, happy-go-lucky girl named Amuro Ninagawa, a transfer student to Umisho, and the other is her father. Her incredible swimming speed makes her an instant hit with the swimming club, but Okiura is surprised, as she reminds him of the mermaid he saw only once in his early childhood. After her floating house is destroyed during a storm she moves to Kaname's house.

The fictional island, where the series is set, is modeled on the real island of Enoshima in Fujisawa, Kanagawa.

Characters

Amuro Ninagawa (蜷川 あむろ, Ninagawa Amuro) Voiced by: Aki Toyosaki

Second year student, and a new transfer student from the Daito Islands, Okinawa at Umishō. Despite her being a dedicated and skilled swimmer, she finds difficulties in performing at competitions due to her not being used to the rules and environment of professional swimming (for instance, in her first attempt at swimming in a pool, she bumped her head on the pool's edge on the opposite end from where she started, and cried for some time from the headache, since she was used to swimming in the open ocean). Among her other uncommon habits, she prefers swimming nude, and has no shame of doing so, especially around Kaname.

Kaname Okiura (沖浦 要, Okiura Kaname) Voiced by: Toshiyuki Toyonaga

Second year student, and the swimming team's manager. He had a traumatic experience involving a creature he describes as a mermaid during his childhood, and after which he has been afraid of swimming ever since. However this scenario started to change after Amuro's arrival at Umishō. Always in trouble due to Amuro's unpredictable behavior, he usually denies his growing feelings for her.

Momoko Orizuka (織塚 桃子, Orizuka Momoko) Voiced by: Hitomi Nabatame

Third year student, and vice-captain of the swimming team. The most rational and serious character, she serves as the straight man of most characters and can't stand the antics of Ikariya.

Maki Ikuta (生田 蒔輝, Ikuta Maki) Voiced by: Ai Shimizu

A first year student, nicknamed Makio (マキオ). Too small for her age, she is usually mistaken as a junior high student. Despite being a member of the swimming team, she is still learning how to properly swim by taking lessons from Kaname.

Masa Ikariya (碇矢 雅, Ikariya Masa) Voiced by: Makoto Yasumura

Team Captain, nicknamed Ikamasa. Third year, muscle-bound, and obsessed with shaving his and other people's body hair, and with wearing revealing Speedo bikini swim suits. He is, in fact, the most annoying character of the swim team, driving most of the characters crazy from his antics.

Mirei Shizuoka (静岡 みれい, Shizuoka Mirei) Voiced by: Yukari Fukui

A second year. Admired by the boys, she is very self-conscious when people stare at her. Her secret promiscuity is a recurring gag in the series: she wears skimpy lingerie under her clothes, she has a collection of kokeshis (Japanese dolls) in her bedroom and although she doesn't like people looking at her, she likes to look at members of the opposite sex or anything that resembles them (ie a giant statue or a large horn). It's revealed when Kaname goes to her house that apparently she got this sexual behavior from her parents, who often engage in sexual roleplay. She is a very skilled swimmer as she almost won the Kantou Tournament in 200 meters the year before the series starts. Her grandfather is the creator of the Shizu Group. She also has feelings for Kaname, however it is uncertain.

Maaya Nanako (魚々戸 真綾, Nanako Maaya) Voiced by: Sayuri Yahagi

First year student. A famous swimmer and model who transfers to Umishō in order to get close to Kaname, for whom she has had a crush since childhood. She considers Amuro as a rival and competes with her for Kaname's attention. She has a noticeable small fang and wears a swimsuit different from the rest of the team. Like Maki she has small breasts, and has a huge contempt for girls with big breasts like Amuro and Shizuka. She forms an "Alliance" with Maki to help make their breasts grow.

Sanae Kise (黄瀬 早苗, Kise Sayane) Voiced by: Ryōko Shintani

A third year student. A co-founder of Umisho's swimming club and Orizuka's childhood friend. Usually tends to bring trouble to those around her. She also makes up stories and lies just to tease others, and to also gain other guys attention.

Chigusa Yasu (安 千草, Yasu Chigusa) Voiced by: Yuka Iguchi

A first year.

Kaori Himekawa (姫川 佳織, Himekawa Kaori) Voiced by: Ayumi Murata

A second year.

Tobe Jun (戸部 純, Jun Tobe)

A first or second year, and another perverted member of the swimming club. He wears large glasses and is quite intelligent. His choice of swimsuit, like Ikuta, is a speedo(albeit more modest).

Iori

A manga only character. He is the personal trainer of Maaya and also happens to be a top model featured in weekly column in swimming magazine. He actually happened to only be Maaya's coach so that he could get close to Okiura, her childhood friend because he really wanted to be his coach. He actually has zero interest in girls and those is in truth he is a homosexual as he says this out loud in front of everyone.

Taku Ikariya

A manga only character. He is the younger brother of Masa and competes in the same tournament as his brother (even in the same events as him). He has also been said to look like his brother only cooler looking (he even is better at swimming and studying then his brother). He also happened to be on the same swimming team as Momoko and Masa in elementary and middle school. He seems to have a crush on Momoko and they seem to get along as well. He goes to Shogyo all-boys senior high school. He seems to have a rivalry with his brother for Momoko's attention.
