Nagasarete Airantō

Ikuto Tōhōin goes overboard on a ship and washes up on an island completely inhabited by women. After meeting one of the girls, Suzu, Ikuto gets ambushed by several other girls who want him as their partner, and they will try anything to obtain him. Eventually, Ikuto tries to leave the island, but discovers the island is surrounded by whirlpools, and thus it is impossible to leave the island.

Obaba sets up a tournament to decide who will become Ikuto's bride. The tournament is simple: The first one to touch Ikuto is the winner; the other two conditions are that the Eastern Forest is off limits and the contest ends at sunset if no winner has been decided. While initially confident, Ikuto quickly discovers he is in a lot of trouble, and Suzu helps him out most of the way.

Ikuto is confident that he can do many of the daily chores the girls do everyday. Unfortunately Ikuto does not have the strength to lift vegetables (that are big in size but normal for the people on the island) the other girls can lift which leads him to depression. When Rin is eventually chased by Yukino, he saves her gaining Suzu and Rin's respect.

This episode contains two separate stories. The first centers around Ayane accidentally eating her older sister's food and Ayane runs from her in fear of her sister's wrath. Machi bribes Suzu with her mother's homemade sweets and gets her to chase after Ayane while Ikuto comes along. In the second part, Suzu breaks a small statue and an evil spirit comes after her, of which she is deathly terrified. In the end it turns out to be a harmless spirit, though Ikuto does not believe it to be a spirit at all.

Kuma Kuma, Yukino's bear friend, goes missing and she starts to search for her with the help of Ikuto and Suzu. At first it is difficult since Ikuto cannot even differentiate between any of the bears, but then learns of a unique crescent-moon shaped marking on Kuma Kuma's chest and Ikuto draws a simple drawing of the bear to aide him in the search while Suzu helps in the search with Yukino's other animal friends.

During an earthquake, the hot spring that supplies bathwater to the entire island gets blocked and must be fixed. Ikuto initially goes to the source alone, but is soon accompanied by Suzu, Yukino, and Rin who help them in removing the dirt from the well. During this time, there is another earthquake and Ikuto and Suzu fall down into a cavern and get out by breaking the rock which sealed the hot springs thus escaping and the hot springs are filled again.

This episode contains two separate stories. The first has the cat lord asking Ikuto and Suzu for assistance in their contest to decide who should be the next lord of the surrounding area, the cats or the dogs. They must paint mustaches onto the dog lord so the cat lord can rule. In the second story, Ikuto goes with his friends to go see the a sakura tree in bloom. On the way he experiences hardships that he does not want to endure.

Ikuto and Suzu have been invited to Chikage's western-style home so that Chikage can secretly observe Ikuto since she has never had the chance to study a human male before. Chikage first dresses up in a maid uniform after referring to several books that have washed up on to the island over the years and then tries to make western-style food, but is unfamiliar with the entrees, so has trouble pleasing Ikuto's stomach; she finally makes curry rice, and Ikuto loves it. The next scene involves Ikuto taking a bath with Chikage's elephant maid Panako. Chikage spies on him without him knowing but is soon discovered when an accident happened. Later, Suzu consults Ikuto about why he can take a bath with Panako which is a female, but not her and Chikage.

Rin invites Ikuto to help her with a construction project, hoping to use this opportunity to impress him as well, though she is oblivious to the fact that Ikuto has no trouble recognizing her feminine qualities. During the project, Mikoto who fancies Rin repeatedly tries to hurt Ikuto as he gets closer to Rin. Ikuto gets worked up when Mikoto challenges him to a duel to see who is better at building. The house gets completed quickly with their hard work. Meanwhile, Suzu, having observed the interaction between Rin and Ikuto, is starting to see what it means to fall in love with someone.

A rainy day means that everyone on the island can take a day off. However, Ikuto cannot sit still for long since he is used to going to work regardless of the weather outside. Ikuto notices how Suzu's personality has changed, and finally finds out that rainy days remind Suzu of her now dead mother. Later, Suzu's friends decide to pay Suzu a visit as they often do during rainy days. Together with Ikuto, they provide Suzu with much-appreciated company.

Ikuto wakes up to find that Suzu has a fever. He is told by her grandmother to get ice, but finds out that all the island's stored ice has been eaten by Kuma-Kuma, Kamo-Kamo, and Kagami (Yukino's mother). Thus, he has to go to the island's mountain Mt. Fuji to get some. After going all the way up the mountain and back again in one day, he finds that Suzu is completely recovered, but he himself has a fever from the changes in temperature and fatigue.

Machi gets scolded by Ayane for not being able to cook, and that a bride needs to know how to cook. Thus, Machi spends the day learning how to cook from Rin. Afterwards, she invites Ikuto and Suzu for dinner, though as Ikuto and Suzu arrive at the gates, a weak Rin warns them not to eat her food before passing out. The two run for their lives before being captured by Machi's Shikigamis. She soon forces them to eat dinner which, despite the bad look, is delicious, but the drawback is she prepared so much that they eventually pass out from stomach pains.

It's Tonkatsu's birthday and Suzu is preparing tofu. Later she and Ayane discover a photo which they believe is Ikuto's "lover" from his world. When Ikuto is discovered staring out at sea Ayane and the others all dress up to charm him. Suzu discovers that he has planned to leave the island and goes after Ikuto. He then tells her that it is his sister's birthday and that he was going to send a letter to her. Ikuto then helps Suzu with the tofu and everyone came to help celebrate Tonkatsu's birthday. During the end credits, a song by Tonkatsu replaces the usual ending theme, consisting only of "Pu"s. After the credits, Suzu helps Ikuto send off the letter in a bottle by encouraging him to throw it past the whirpools. Upon success, their relationship becomes noticeably stronger.

An unknown robber is stealing food from many people on the island and Machi is initially suspected due to her stealing other food amid her naturally evil behavior. After some investigating, Ikuto discovers a pattern to where the robber is stealing from, and he and his friends stake out the next two houses they expect to be hit next. In the same night, both houses get robbed by two separate culprits, but they both get away. Later, Ikuto and Suzu are going home to sleep, but one of the robbers is inside taking a bath. After some explanation, the robber introduces herself as Mei Mei who had recently washed up on the island during a storm with her friend Tona. Now Ikuto and Suzu must protect Mei Mei for the time being while they try to track down Tona.

Ikuto and Suzu turn an old waterwheel house into Mei Mei and Tohna's new house. Mei Mei, due to her chronic shyness, is having difficulty interacting with the island's other residents. Ikuto and Suzu attempt to cheer her up and help her adapt. Ayane later arrives and gives Mei Mei a 'pep talk'. During the conversation she notices Tohna and seems to show a puzzling recognition of him. However, when Ayane realizes Tohna is a Kappa, she takes off screaming. Tohna believing that Ayane has seen other kappa before pursues her. This leads to a high-speed pursuit around the island. Mei Mei sees that Ayane is about to run over a cliff and uses her acrobatic skills to stop her. The group later learns that Machi would dress up like a kappa to scare Ayane, causing her phobia. Several of the others arrive to cheer up Mei Mei, and the shy girl thanks them all and promises to do better.

When the South Leader comes into the West Leader's territory to deliver a message to the West Leader, he tells Suzu and Ikuto that the East leader had gotten beaten. They are all in shock. The former East Leader goes to get revenge but sees Mei Mei and falls in love with her and says that the rematch does not matter. Then the former North Leader shows up and stops the former East Leader from running away. Suzu and Ikuto find out from the former North Leader that Mei Mei is the new North Leader and must return to the Northern Forest. However Ikuto will not let the former North Leader take her there so he decides to fight him. Ikuto gets beaten up through most of the fight and Suzu and Mei Mei try to either end the fight or try to fight the former North Leader, but Ikuto does not let them. Ikuto gets some assistance from a shadowy figure and wins the fight. Come to find out it was one of the new Leaders, which looks like a chicken, and the former North Leader returns to the Northern Forest.

Chikage found a magic book and decided to use the spell locked in it. One morning Ikuto woke up and saw Suzu as a cat while Ikuto was a dog. Ikuto finally figure it out that humans turned into animals while the animals turned into humans. Along the way they meet their friends that turned into animals. They found out that it was Chikage who was responsible. Before Chikage attempts to demonstrate her magic on a hapless Ikuto, Panako, who was turned into a human, appears. Still maintaining her elephantine strength, Panako throws a huge rock at Chikage because she broke a promise to Panako, destroying the book and returning everyone to normal. Because Ikuto was rendered unconscious through part of the ordeal, upon waking up, he thought it everything that happened was a dream.

Shinobu, one of three sisters that is a ninja, receives a notice that there is a strong swordsman back in the village where she came from named IKUTO. The rumors that she heard is that he made a 100 dolls just by cutting a tree, can cut a rock with a wooden sword, and that he can depart a waterfall with one strike. She also heard that he beat North Leader so she heads out to fight him. Ikuto and Suzu find Shinobu on their way out and take her back to their house to feed her. Shinobu then declares that she will not leave his side until he fights with her. Finally it goes so far that a jealous Suzu tells Ikuto to accept her challenge. The battle begins and the two nearly equal. Shinobu is fast but Ikuto had proper techniques. Shinobu trips and Ikuto goes to catch her but his hands touch her breasts. Shinobu is in shock and can't walk or stand up. Ikuto wins the fight just with the touch.

Ikuto and Suzu are invited to a hotspring resort. They are greeted by Sakuya, a mechanical doll built 130 years ago. Soon the others arrive and begin to start a competition for bathing with Ikuto. Suddenly, the masked fiend Beniyasha appears. Who is this masked man?

Beniyasha has succeeded in taking out the girls one by one, except for Rin and Machi who were distracted. Though none are hurt, his "attacks" cause many problems and nosebleeds for Ikuto. After a rooftop confrontation, Ikuto tries to chase after him. Unknown to everyone else, it was actually Chikage's mother in disguise. She and her daughter had a talk about him and how he could be the master of the next generation. This could mean the ninja clan that Chikage and her mother come from.

Ayane is out searching for her sister and Ayane thinks that Machi is with Ikuto. We then find out that Machi was hiding in the bushes. She walks into a statue and knocks a seal off of the statue and a 2-tailed shape shifting raccoon appears. Machi is then in search for the 2 tailed raccoon so that she can seal it back up. The only feature that gives away is its belly button is bulged out and has a white X on it. Suzu and the others help trying to find it. When Suzu and Machi are sitting with Ikuto Suzu keeps saying it is impossible and Ikuto keeps agreeing that it is impossible(?). Suzu then grabs Ikuto and says that they have the 2-tailed raccoon captured. They seal up that raccoon for another one thousand years.

Yukino is walking home from the forest and sees the mysterious blue bird that is mentioned in a fairy tale. Yukino see Suzu and drags her along to go find the mysterious blue bird. They end up not finding it, but finding another bird that has never been seen before. The bird is small and a gray color (this is the blue birds other form). They chase the bird and end up falling into a cave and can't climb out. Suzu gets injured on the fall. Ikuto goes in search for Suzu and Yukino. While Ikuto is out searching for them it starts raining; then all of a sudden Ikuto hears his name being called and stops. The blue bird appears and takes him to Suzu and Yukino. Rin, Ikuto and others help get them out of the cave. Ikuto thanks them and then Suzu and Ikuto start home. Ikuto then finds out that Suzu is hurt and gets mad at her; however, Ikuto says that Suzu is his family on the island and Suzu becomes extremely happy. Ikuto ends up carrying her on his back.

Suzu hates studying so much that she runs away from the school building or away for even mentioning school or studying. Ikuto and all the others come up with a plan to lure her there so that she can study with them. When they all arrive she runs away again and Ikuto runs after her to say come back and give it a try. When Ikuto throws Tonkatsu at Suzu to stop her; she dodges it and falls on Ikuto's face and he plays dead until she starts to walk by and he grabs her foot. Ikuto takes off her boot and tickles Suzu's foot until she gives up and agrees to go back with him. She ends up finding out that he is a teacher and she gets excited. After the credits Suzu and Ikuto are going over numbers multiplied by two. When she gets "9*2=18", Ikuto says good job and gives her his portion of her favorite food.

While Suzu was collecting seaweed by the coast, a bottle drifts ashore. Upon looking at it, she immediately presumed that it was the bottle that Ikuto had sent to his sister Misaki. She came back home to show it to Ikuto, and while reading the letter, it read that his sister went off to the sea to try to find Ikuto, but has gotten lost; therefore, Ikuto, Suzu and the other girls attempt different ways to get Ikuto out of the island to find Misaki.

Suzu and Ikuto search for a key that would open a special gate to a Sea Dragon God, but the leaders of the North, South, East and West try to intervene on Ikuto's quest for the key.

Ikuto and Suzu arrive on a small nearby island to the cave and gate where the Sea Dragon God sleeps, in which the dragon can send Ikuto off the island and to find his sister Misaki. After meeting her and learning she's safely living on a male version of Airantou, he makes the decision to go back to the island much to her dismay. Upon his return, he is welcomed by all the girls on the island and Obaba informs Ikuto that he will have to go through another tournament that would decide which of the girls on the island would be his bride. The story ends with Ikuto being chased by all of the girls on the island.
