Kenkou Zenrakei Suiei-bu Umishou

Within the Kanagawa prefecture lies the seaside city of Umineko.

There, Okiura Kaname, a second-year high school student, attends Umineko Shougyou High School (Umishou). He is also the manager of Umishou's swim team though he himself does not know how to swim.

In fact, he is afraid of the water stemming from an incident that occurred some years ago.

While he was at the beach, he nearly drowned when a mermaid pulled him under water.

He joined the school's swimming club in order to learn how to swim, but the club is filled with weirdos, who never taught him how to swim.

One day, a floating house arrives at the shores of Umishou bearing two new arrivals.

One of these is the cheerful, sunny, happy-go-lucky girl named Ninagawa Amuro, a transfer student to Umishou, and the other is her father. Her incredible swimming speed makes her an instant hit with the swimming club, but Kaname is surprised, since 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 live at Kaname's house.

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

EP1 - Churaumi!

This introduces the characters and the setting. On the beach, Momoko Orizuka and Kaname Okiura are relaxing when a houseboat comes in. On that houseboat is Amuro Ninagawa. She is holding a 3-foot-long (0.91 m) shark in her hand. She comes in and offers the shark to Momoko. Momoko refuses, saying she doesn't like a dead shark. Amuro says the shark is still alive. It then springs to life in Amuro's hand and tries to bite Momoko, but ends up tearing Momoko's swimsuit top off. Then Amuro dives into ocean, seemingly vanishing, only to emerge some distance into the waters within seconds, impressing everyone, especially Momoko.
EP2 - I Might Be... Interested...

Amuro is introduced to the swim team after being invited to join by Orizuka. Amuro meets the rest of the Umisho swim team members; she mistakes Makio for a middle-school student, for example, and makes a note of Shizuoka's chest size (much to Shizuoka's embarrassment). Ikamasa introduces himself in typically embarrassing fashion. The next day, Amuro and a reluctant Kaname walk to school together (they are neighbors) and this causes some comment among the rest of the school. Swim practice is show to be, at best, unproductive. The normally shy Shizuoka keeps saying things to Kaname that could be misinterpreted. On the way home that day, Amuro discovers a new local celebrity by accident.
EP3 - I'll Show You!

The team attends the local tri-meet swim competition in a neighboring town, and is showing poorly (all the boys finish in last place). When it is Amuro's turn (50m Freestyle), she easily outpaces the other swimmers but is disqualified as no one had told her that she had to surface after 15 meters. Umisho ends up in last place in the meet. After the meet, there is time for a break from school activities and while Kaname would like to spend the time playing video games, Amuro shows up and drags Kaname to the beach -- partially to show Kaname her new string bikini! Kaname wonders whether or not they are on a date. At the beach, they meet up with Ikamasa who is busy pranking beachgoers in a realistic shark costume. He, too, asks if Kaname and Amuro are on a date. In a postscript to the episode, Ikamasa is having trouble focusing on the upcoming swim meet as his family Japanese restaurant is experiencing competition from a trendy new eatery next door. The team tries to come up with ideas to help, eventually settling on having the female swim team members wait tables in their swimsuits -- an idea rather surprisingly suggested by Shizuoka. This goes over rather well with the male clientele (although not so much with the girls) and the restaurant is profitable as never before. The girls are roped into a second evening waiting tables but it all starts to go wrong when Ikamasa and his father get greedy...
EP4 - I'm Going to Show You

After the team's poor showing at the Tri-Meet, vice-captain Orizuka decides that what the team needs to succeed is teamwork, and a training camp is just the thing. Typically, the training itself starts out like just another practice with much goofing-off and little actual practice. Orizuka becomes enraged and begins to whip the team into shape but all this changes when she is fed a poisonous mushroom from Ikamasa's backyard grill (!). She soon begins to act oddly, stripping off her swimsuit! When Ikamasa (the ostensible team captain) is told to stop her -- he joins her instead. After the practice the girls adjourn to the bath (where Orizuka claims not to remember a thing), they are not joined by Shizuoka who is hiding a secret. She goes to the bath after the girls are finished, but the boys are next in line for the bath and Shizuoka is in danger of being caught -- when the power at the school suddenly goes out due to a storm. Meanwhile, some of the girls have gone to Amuro's house for snacks and are trapped there by the same storm -- which washes Amuro's houseraft (with Amuro, Makio and Orizuka on board) out to sea!
EP5 - Do You Want Mine, Too?

With their houseraft wrecked by the storm, Amuro and her father are invited by Kaname's parents to stay at their house until repairs can be made. While initially interested in having a girl living at his place, Kaname soon becomes infuriated at Amuro's lack of understanding about privacy and her total lack of modesty. The next morning, Kaname and Amuro are accompanied on a morning walk to a local temple by Amuro's father who is in need of building materials. Amuro's father begins to take items from the temple itself, to Kaname's horror. We see Shizuoka in the temple itself, learning that she goes there to look at the statuary. She hides from Amuro, who barges into the temple with Kaname in tow and Amuro proceeds to eat the temple offerings. She is discovered when she overhears Amuro and Kaname and totally misunderstands their conversation. Later, Kaname tells Amuro off for being so carefree. Amuro runs away and while chasing her, Kaname runs into Amuro's father who fills Kaname in on some of Amuro's troubled background. When he cannot find Amuro, Kaname recruits Orizuka, Makio and Ikamasa to help in the search.
EP6 - No!

The Ninogawa houseraft reconstruction is proceeding smoothly. On the way to school, Amuro meets Maaya Nanako, a model and competitive swimmer. They are soon surrounded by a crowd which includes Kaname, who apparently was childhood friends with Maaya (although they have differing memories of said childhood). She has transferred to Umishou and will be on the swim team. It soon becomes apparent that Maaya is a master manipulator, particularly of men, although Kaname is apparently immune. At swim practice, Maaya soon has the other male members of the team wrapped around her finger. Because of her own inadequate feelings compared to the other female members of the team (who are all bustier than she is), she convinces the boys to build a new changing room for her alone. It all goes rather poorly for then entire team.
EP7 - Curse

There's only one week left until the Prefectural swim tournament. But there's a problem; Amuro has lost one of the X s she wears on her head. Given to her by her grandmother, Amuro was warned that she was to wear them all the time and Amuro would be cursed if they were lost. Amuro is basically unable to function without it. The X was blown off her head by a gust of wind as she was diving into the pool, and a merry chase ensues as the team chases down the X so that Amuro will be able to compete. It finally lands on Maaya (who was skipping practice) and she throws it away in a fit of jealousy when informed that it belongs to Amuro. Fearing the X lost for good, the team tries many options to replace the X so that Amuro will feel better. Of course, none work so the team, prompted by Kaname, decides to resume the search. Along the way, Shizuoka finds something she really wants, Sanae finds someone she really wants, and the team must finally resort to going to a temple to ask for divine intervention...
EP8 - Take A Good Look

The Prefectural tournament is the next day. Orizuka orders the team to have a good rest in preparation, and the team breaks for the day. However, Ikamasa requests that the boys come to a meeting that evening in the girls' club room. However, the meeting has nothing to do with swimming; Ikamasa has always dreamt of playing Mahjongg in the girls' room and since the girls won't be back until morning, now was his chance. The boys realize that they have never been in the girls' change room and, since the girls are less than kind to the boys, they decide (against Kaname's wishes) do a little exploring. This does not go over well with Orizuka, who discovers them the next morning. On the day of the tournament, Orizuka is challenged by her old rival Nanjou Karena from Shinomiya University High School who has bested Orizuka at all their previous meetings. The Shinomiya girls have a strong team, but Orizuka is convinced that Umishou is just as strong. However, the on the boys side there is somewhat less enthusiasm. As the girls' events unfold, Umishou beats Shinomiya in five straight events but with Orizuka, Amuro and Nanjou all competing in the 100m Freestyle finals, Nanjou comes up with a little bet to make things more interesting...
EP9 - Help Me Forget...

The Umishou team had a good showing at the Prefectural tournament, with seven swimmers progressing to the Kantou tournament. However, Orizuka is forced to go to the student council to have the swim team's budget increased for the trip. In the meantime,on their walk home from school, Sanae explains to Makio, Amiuro and Kaname that it would be easier to increase the budget if they had an adult advisor. In her own way, Sanae tells how she, Orizuka, Ikamasa and an adult coach formed the swim team. Kaname, who has heard Sanae tell this story before, says the story has changed since the last time he heard it. However, he has not heard why the coach left, and Sanae continues with more than a bit of a yuri twist. However, Orizuka meets up with the trio (while Sanae sneaks away) and tells her own version of the story, correcting Sanae's version on more than a few points. In an episode postscript, Makio proposes that the team get an Internet homepage. After a false start it becomes wildly successful once Makio sees what people are looking for on the Internet...
EP10 - Breast Massage?

It's time for the Ono Island Summer Festival. Amuro and Kaname are enjoying the sights when they are mey by Maaya, who insists that Kaname spend the festival with her instead of Amuro. However, Kaname still has bad recollections of Maaya bullying her as a child. His refusal is interpreted by Maaya as an insult towards her small bust size and she runs off. Kaname and Amuro are then joined by the rest of the female members of the team, while the angry Maaya is met by Makio. Makio confesses to Maaya that she is also concerned about her small bust and that she would just once like to zip through the wind with her boobs . While she initially dismisses the idea, Maaya becomes intrigued when Makio tells her about a secret technique to increase bust size, and the duo retires to the ladies' room. Meanwhile, the rest of the members find Ikamasa manning his father's fishing booth at the festival. While the fish are expensive (Ikamasa's father will cook any fish caught) the games are rigged. That is for everyone except for Amuro. Through a turn of events Kaname finds himself competing against Amuro and her father at a watermelon eating contest. Back at the ladies' room, Maaya and Makio corner Shizuoka on why her bust is so large. We return to the watermelon-eating contest where Kaname is determined to win -- the penalty for losing is a drop into a dunk tank! The episode post-script follows male swim team members Takeda, Tsunime and Jun through the festival on their quest to meet cute girls . The girls they meet, however, are not who they expected...
EP11 - Could It Be...

It's a week to the Kantou tournament. Maaya gives the team an idea: if they win, Kaname is to do anything the swimmers tell him to do because, after all, managers have it easy . While initially reluctant, Kaname eventually agrees as it will help with team morale. The team makes it through a weeks' training and arrives at the hotel at Kantou. They discover that the hotel has an open-air bath. The Umishou team is surprised by the appearance of Nanjou and the Shinomiya team who immediately challenge them to a contest: the first team whose members all stand up from the hot spring must shave their under hairs ...in front of the losing team! The next day is the preliminary swim meet but the female team members of both Umishou and Shinomiya are suffering somewhat from the previous night's competition -- prolonged exposure to the heat of the bath has sapped the team members of their energy and all place poorly. Most affected is Maaya, who is crushed by her seventh-place showing and runs away. However, Shizuoka finds her by accident and gives Maaya a pep talk to bring her around and show that losing is not the end of the world.
EP12 - Oma Oma

It's the second day of the Kantou tournament. Renergized, the team begins to come together again and scores several victories in the preliminaries. Amuro reminds Kaname of the promise he made: if the team members win their events, he is to do whatever they tell him to. Takeda suggests to Kaname that Amuro might want a kiss. Amuro spots the members of the Tamatsuka Academy team who will be competing against Umishou in the Medley Relay preliminaries. Tamatsuka has a large contingent and Amuro is greeted warmly (very warmly) by the leader of the team. Amuro then discovers that there is free swim practice and dives straight into the pool where she collides with the Tamatsuka swimmer -- who doesn't seem to recognize her and runs away. Chasing the swimmer into the change room, Amuro catches her again, but this time the girl is on a mobile and ignores Amuro completely. Confused, Amuro leaves the ladies room and again collides with the Tamatsuka swimmer -- coming from the opposite direction as the one who had just left. All is revealed at the start of the Medley Relay: the Tamatsuka competitors are quadruplets! However, the Tamatsuka team has another trick up their sleeves: the cheering section is actually a choir and they begin to sing the school song to synchronize their swimmers. Ikamasa gets the wrong idea from this and just begins to sing as a way to cheer; Makio and Amuro quickly follow suit singing whatever they feel like. As the swimmers come toward the final leg, Shizuoka catches up to the Tamatsuka team, but Orizuka (swimming anchor leg) is late to leave. To make matters worse, she suffers a leg cramp. Finally, the Umishou team gets it together singing the Ono Island Dance Song. This (plus a surprise from Ikariya) is enough to throw off the Tamatsuka singers and Orizuka has a chance to catch up. It is a pyrrhic victory, however, as Orizuka's cramp turned into a pulled muscle which not only knocks her out of the medley competition but has a chance of endangering her swimming career...
EP13 - Mermaid

It's the Medley Relay Finals! Amuro has been chosen to replace Orizuka on the team. At the end of the first leg, Umishou, Tamatsuka and Shinomiya are neck and neck. Sanae, swimming breast stroke, falls behind Tamatsuka and Shinomaya into seventh place. However, Shizuoka, swimming butterfly, quickly gains several places and Amuro is set as anchor with her signature, unique mermaid style. Miraculously, she catches the other teams and pulls out a come-from-behind victory. With this win as the basis, several more swimmers (including Ikariya) make it to the Inter-High competition. For Sanae and Orizuka, the episode ends with them reflecting on their three years on the Umishou team. For Amuro and Kaname, however, things end differently. Amuro reminds Kaname about the bargain -- he has to do anything she wants. Kaname still believes she will want a kiss, and prepares himself. However, Amuro simply wants to go swimming with Kaname. It is revealed, when Kaname slips into the water accidentally, that Amuro is indeed the mermaid he saw several years before on Okinawa and she saved him when he slipped from the rock on which he was standing. The next day, at practice, everyone else begins to demand their own rewards, and when Amuro asks for hers, Kaname reveals that she got hers already. This causes an uproar and the accusation that the two are dating. Kaname denies it, but when asked by Makio, Amuro simply replies, you guys found out? . An extended end-credits scene presents a series of stills (essentially scenes from the manga) showing the team traveling to Okinawa for the Inter-High Tournament.
