Natsuiro Kiseki: Season 1

A few days before summer vacation, Natsumi Aizawa falls out with her friend, Saki Mizukoshi, when she decides to quit the tennis club. The next day, Saki reveals she is transferring schools, which upsets Natsumi. Wanting them to make up, their other friends Yuka Hanaki and Rinko Tamaki call Natsumi and Saki to a large rock at a shrine temple they used to visit in their childhood, said to grant wishes to friends who wish for the same thing. As they gather together at the rock and casually observe

The day after they flew, Natsumi and Saki are still hostile towards each other. As Yuka and Rinko hang out at the rock and casually think that Natsumi and Saki are best when they're together, the rock's magic activates, causing Natsumi and Saki to become literally stuck to each other like magnets, finding themselves unable to pull away from each other. Realising this is Yuka and Rinko's doing, Natsumi and Saki cooperate with each other to chase the culprits across town. As the chase reaches its

Natsumi hears from her brother Daiki about what Yūsuke claimed to have seen. As Natsumi advises the others to be careful about flying haphazardly, she and Saki make a little revenge wish to put Yuka and Rinko through what they went through the other day. As Yuka and Rinko find they are unable to get unstuck as easily as Natsumi and Saki did, Daiki and Yūsuke fall out with each other when Yūsuke takes his witch theory too far. Later, Saki runs into Yūsuke and hears about the troubles he is facing

As Yuka learns that her cousin, Takashi Sano, who she has a crush on, has feelings for Saki, she unconsciously wishes she could be like Saki whilst sitting on the rock with Rinko. The rock's magic activates, causing Yuka to end up in Saki's body and vice versa. Yuka takes advantage of being in Saki's body to ask Takashi on a date, much to the displeasure of Saki. As the girls attempt to wish to return things back to normal, things only get worse Natsumi and Rinko end up switching bodies instead.

After getting caught in the rain, Rinko ends up with a fever. With Rinko's parents going out for the day, Yuka cancels her plans to get a special poster in order to take care of Rinko. Meanwhile, Natsumi and Saki are invited by their seniors to join a tennis tournament. After Rinko recovers from her cold, Yuka catches one of her own. As the others hang out without Yuka, they recall how it was because of Rinko's odd visions and Yuka's support that the four of them became friends and begin to thre

At Natsumi has her hands full with tennis, studying and looking after Daiki whilst her mother's away, Yuka, Saki and Rinko make a wish on the rock which causes Natsumi to split into two. Whilst obviously displeased with the arrangement, Natsumi starts putting good use to her doubles to get things done, with one Natsumi doing tennis practise and the other doing homework and chores. However, as the day of the doubles match comes, Natsumi notices her tennis-playing double is pushing herself too muc

As the town prepares for a festival, Natsumi is at odds with Yuka for not practising for a talent competition. As Natsumi and Saki prepare for the competition and Yuka and Rinko get some last minute practise in, a sudden rainstorm appears, meaning the competition would be cancelled. Wanting the competition to go ahead, Rinko and Yuka decide to wish for the rain to stop, allowing the four to compete together and win the contest. Afterwards, they reveal it wasn't the rock they wished on, but some

As the girls debate going on a trip together before Saki moves, Natsumi suggests they go to Shimada. As the girls prepare for the trip, Saki has a nightmare about being left behind by the others. The day of the trip comes and the girls soon arrive in Tokyo and spend the night on a ferry. As Saki once again experiences the same nightmare, Natsumi tries to get her to be more honest about her feelings. Upon arriving in Shimada, Yuka almost drowns in the sea but is rescued by a lifeguard who seems a

Upon arriving at their accomodation, the girls meet Chiharu Okiyama, the twin sister of the lifeguard from earlier, Koharu. Whilst trying to hide Saki from the neighbours in the hot springs, they inadvertently discover a wishing rock in the hotspring that causes Saki to turn invisible, unable to be seen or heard by the others. Later that night, as Natsumi talks with Yuka and Rinko about her desire to stop Saki from moving, they remind her that they'll still be friends regardless. The next day, t

As the city receives a typhoon alert, the girls recall an incident when they explored a supposedly haunted hotel. With no one quite sure of what actually happened, they try using the wishing rock to remember, although it doesn't appear to work at first. However, when they get home, they find that their younger selves from four years ago are walking about. The girls follow their younger selves as they prepare to explore the haunted hotel, oblivious to the time period they are in or the approachin

After a bout of training, the girls soon head to Tokyo for their idol audition, where they get some last minute practice in. However, when they arrive, Yuka is suddenly overcome with nerves after witnessing the intensity of the rival competitors. Although the others assure her that she is what has made the summer vacation so far as unique as it is, Yuka is still nervous during the interview section and ends up falling down during the dance section. After failing the auditions, Yuka laments how s

The girls soon realize they have gone back to the beginning of the previous day, which Yuka sees as a second chance to try and pass the audition, though it once again ends in failure. Later that day, they discover a shrine from the same family as Rinko's which has its own wishing rock and soon realize it has granted their wish for a never-ending summer vacation, which is proven when they end up looping the day over and over again. As they continue to loop, they forgo the audition and instead opt
