Horror!? Summer Island (戦慄!?サマーアイランド) is the 143rd episode of Aikatsu! TV anime series and the 42nd episode of its "3rd Season" (3年目(サードシーズン) lit. "Third Year"). The episode aired on July 23, 2015.


It's finally summer vacation and as an arrangement made by Headmistress Orihime, everyone is excited to be celebrating together. However, she worries as everyone will be celebrating on a deserted island. While enjoying the beautiful sea and blue sky during their time there, the girls encounter the "Chupachupa Turboméca of the Deserted Island"...!?


Akari and Sumire are trying to determine why their plans for the day are suddenly wiped off of their schedules. They are joined by Juri and Hinaki, who had the same thing happen to them, along with Rin and Madoka. Orihime suddenly reveals herself to the confused group and explains that she gave everyone a summer vacation. The girls waste no time celebrating the exciting news before Akari and Sumire leave to go perform one last time before then.

After, the girls discuss how much fun the concert was before they meet up with the others in the Cafeteria. Madoka asks where they should go for their vacation, causing Hinaki and Juri to discuss how summer is used for the beach. Rin is worried about this idea though, pointing out that the beaches may be too crowded for them, and if they all showed up together it could become bothersome. They are joined by Naoto, who reveals that Orihime told him about a special beach spot for the idols to go to; where they do not need to worry about being bothered. He agrees to set up arrangements for the girls and Akari thanks him.

That night, the girls are busy packing. Akari is very excited, since she has never gotten to go to the beach before. She's never wanted anything more than getting to play beach volleyball with her friends, but Sumire warns her that if she was to get too excited she might oversleep. Akari claims that she may be too excited to sleep at all, but realizes that neither of them know where they were supposed to meet up the next day.

The next day, the girls observe Naoto's cabin cruiser that he will use to drive them over to the beach. They are joined by Akari, who stares in alarm upon realizing this very dock was the same one that led her to that hard idol boot camp she was forced to attend a while back. As the others question this, Akari tries to claim that nothing is wrong and convinces herself to just get excited again. Naoto calls for them to let them know he's ready and Akari quickly grabs her items; only to forget her beach volleyball.

While everyone enjoys their ride over to the island, Akari continues to think about her horrible time at the boot camp, realizing the island looks like it. As she is able to convince herself that she is over thinking it again, she suddenly sees the sign and stares in disbelief while the others discuss it. They notice something is off again and Hinaki reveals that Akari was sent here. She mentions being at her worst when she was sent here, but now that she looks back on it, she is also grateful for all of the hard work. Suddenly it occurs to Akari that they may have been tricked into coming here, and the girls express surprise at the realization; only for Naoto to claim that the boot cam isn't in season right now. It's basically deserted, which is why it's the perfect spot for an idol to vacation.

Excited again, Akari runs in to unpack her items. But to her sadness, she accidentally left her beach volleyball behind. While depressed, Hinaki claims there is a bunch they can do, with the other girls showing up with items; such as Sumire holding a inflatable dolphin, Madoka with an inner tube, Rin with tennis rackets, Hinaki with a water gun, and Juri with a board. Akari perks up soon enough and together the girls change into their swimsuits and run out to have fun. As this goes on, Naoto sets up a small area for himself to relax, but he reminds the girls to stretch first.

The girls do a variety of activities for a while, but for a moment Akari is reminded of how much she wanted to play volleyball with the other girls. However she doesn't feel as sad as she did before, so she watches with the others as Juri and Rin decide to have a race in the water. As this goes on, Akari helps Madoka learn how to swim; but the girls are forced to cut their time short after the sky suddenly darkens and begins to pour down rain. They run back and grab their shirts, deciding to take a break for the time being.

To lift their spirits, Akari pretends to host an idol program show. She asks for each girl to tell them a story or an experience they have had. Juri tells a story about the super-hot summer-colored tomato sauce her grandfather makes, then Sumire tells a story about the Chupa Chupa Chrubomega. She reveals that the island it lived on was a lot like this one, and she points out that everyone who tells the story ends up vanishing. The story effectively startled the girls, except for Madoka. With the sky clearing up they decide to hold lunch and set up a barbacue, but by now they realize Naoto is missing. Rin panics as she recalls what happened in the story and spots his swim trunks, which got left behind while the rest of his items are missing. Then as Hinaki reveals that their boat is missing, Rin passes out.

She recoils from the shock and starts to panic. The other girls believe that she is only overthinking it though, since they believe Sumire's story to be made up. Juri suggests that they should try to look for Naoto first and the girls head into the forest. They are able to find his items scattered around, causing Rin more panic at the idea that Naoto would be eaten by the scary monster. As Akari worries that it will happen to him she asks Sumire to read them a fortune; however, it scares them further, and even as she puts a pleasant spin on it, it doesn't help much.

With the other group, they try to call for him and see something jumping around. Hinaki and Juri run up ahead, along with a worried Madoka.

After a while Akari spots Hinaki's phone, while Rin finds Juri's hair piece. This makes them worry further that the Chupa Chupa may have already gotten them. Akari continues to call for Hinaki, but to her surprise she is grabbed by Hinaki and she has her shush, so that she can show her something. With the girls together again, they follow to find a group of monkey playing with their items. Juri then recalls how Naoto is still missing, causing Rin to say that he probably got eaten by the Chupa Chupa. However, Naoto rejoins the girls with the boat. As it turns out, he actually ran back to fetch Akari's beach ball since he knew how much she was looking forward to it.

Akari is very happy about this, but she asks that he tells the group about what happened; considering he vanished the way he did. With that, the girls start their game of beach volleyball, then they bury Naoto in sand, swim, have barbecue, and finished the day by enjoying shaved ice. They share a cheer while watching the sun set in the distance.



  • That deserted island the girls are going to is the same island that hosted the Aikatsu! Boot Camp in Episode 80.
