A Promise to the Future (未来に約束) is the 121st episode of Aikatsu! TV anime series and the 20th episode of its "3rd Season" (3年目(サードシーズン) lit. "Third Year"). The episode aired on February 19, 2015.


As Miyabi is preparing to leave for home and a final performance, Akari tries to deal with having to say goodbye to her new friend.


Miyabi looks over her journal and notices that she has not wrote in it for sometime. It wasn't that she didn't want to, but she had so much to write that she had no idea where to start. She notes that she only has three days left at Starlight before she has to head home to Kyoto.

Akari meets up with Sumire, Juri and Hinaki, then she announces herself as the Party Planner related to Miyabi's send off party and the girls begin to discuss. Akari looks back to her first interaction with Miyabi, then comments on how they did so much this past month, so now she feels lonely realizing she has to leave. But it isn't their style to be sad so she wants Miyabi to leave with nothing more than happy memories.

Later on in Orihime's office, they brief Miyabi about a special performance. In honor of her last day as an exchange student they wish to have her perform on a special stage. She is free to perform solo or bring friends to perform with her if she wishes, and Miyabi asks if she can use the stage as a competitive concert. After she leaves, Orihime mentions surprise, since she assumed Miyabi would have used this to perform with Akari and the others. But Johnny claims this is fitting of Miyabi and they wonder who she will decide to challange.

Miyabi steps in Sakura's path while she runs around the track. She thinks about their time in the past when they performed in the Yamato Nadeshiko Festival and decides that she is the only person to challange. So she asks Sakura to accept it and an announcement is put out to reveal it.

Akari is highly shocked and she asks why Miyabi is doing this. Miyabi explains that she wants it as the compilation of her exchange experience, then shows them how she has a profile of Sakura already put together. She is very amazing in her eyes, and Hinaki mentions that Sakura is a top contender for the Starlight Queen Cup the very next time it comes around, causing Miyabi to outright state that she can't stand up to Sakura just yet. She is putting more pressure on herself using this competition and takes off to begin to train.

She spends the day running for a while until she decides to stop for a break under a big tree. She thinks about a time when she did it before and had been called under the tree with Hinaki and Akari after they spotted her. Then she heads to the training room to practice singing and thinks about the time she and Akari rolled on giant balls, then begins to practice her dance while thinking about her training with Juri.

Miyabi thinks about the times she has had in a month while she heads to the dojo. She recalls another time when the girls had finished training, but stops as Sakura comes by. To her surprise she finds her standing behind her and notices that she is carrying the same supplies.

Elsewhere, Hinaki shows the girls helping her design the decoration idea she drew. They compliment how nice everything goes together and how it fits Miyabi, which Hinaki eagerly agrees to. In the nearby room, Sumire and Juri take notes from , who shows them the best way to handle confections using matcha as an ingredient. He comments how happy he is to be helping them to fulfill such a wish and the girls thank him.

In the dormitory, Akari stares at the long, blank piece of material. She has no idea what to write on the banner and happens to spot the origami bunnies they made a while back. While she didn't think hers was any good, Miyabi claimed the opposite, which made her feel a lot better, but she feels sad again. She is joined by the others and she reveals that she didn't do anything yet since she doesn't know what to write. She shows them what she has considered but they all feel too sad, so Hinaki suggests that Akari get her mind off of it by going to do something else for a while. She tells her that maybe inspiration will come if she goes to visit Miyabi, but Akari is disappointed with the idea of not helping out. But they convince her that they wont even start putting things together until later on anyway.

Akari heads to the Dojo and runs inside while hearing noise. She watches the two girls train and is pretty surprised by the sight, crying out in alarm. She greets them as they end the match and they mention not even realizing she was there, having been so engrossed with their naginata practice. Akari admits that she had no idea Sakura practiced naginata and Sakura points out that while she isn't a practitioner of it, she often partakes in training before a decisive match.

They begin to discuss the concert again and Sakura promises that she will make sure to give it her all as a Starlight Academy Student. Miyabi thanks her, then asks why Akari is there. Akari admits that she came to visit Miyabi but worries now that she is only interupting, but Sakura tells her it is okay by her, as does Miyabi.

As the sun begins to set, the girls change and Sakura leaves. Miyabi compliments Sakura and Akari suddenly realizes how much Miyabi has changed. She recalls how she was able to shed her hesitation she originally presented upon arrival to Starlight, and now she seems to have truly discovered her Aikatsu. Miyabi wonders if this may be true and comments that meeting everyone helped her a lot more than she imagined. With that they exit and Miyabi decides to run off for a jog, leaving a depressed Akari behind.

Akari heads to a room and begins to practice making an origami bunny again. She is joined by Sakura, who comments on the bunny before asking to speak to her. They get some tea and Akari explains how sad she is knowing Miyabi has to leave. Sakura claims she can relate and recalls how Ichigo left for America three years ago. She was so sad watching her leave but she learned something new, the stronger the bonds between two people, the harder it can be to part. But she also learned in this time that because of the bond, no matter how far apart they may be, their hearts will remain connected. After she hears this Akari suddenly realizes that Sakura has a point. Even though Miyabi will be leaving it doesn't mean this is goodbye.

The day of the Special Live finally arrives. The girls stand together and wait for Miyabi, and to their surprise they observe her wearing the Starlight Uniform. They are all taken by it and compliment how cute she looks, but Miyabi is embarrassed over the skirts length. Akari asks her what made her decide to wear it however, and she plans that she had wanted to wear it to become one of them, and she always found it to be cute. She then scolds Hinaki for calling her cute and the girls share a cheer before she and Sakura run off to change. They appear on stage and perform to Light Pink Day Tripper.

After the performance it is revealed that Sakura is the winner. Everyone cheers for her and Miyabi claps, showing her approval for the result. While the girls are sad she lost, they are also happy by how well the performance went. Sakura and Miyabi promise to stand on the same stage again, and back in Kyoto, Nagakao-sensei is shown having watched the performance and he comments on how befitting her name is.

After, the girls head to the send off party. Akari has Miyabi speak and she tells everyone that she has learned a lot and she plans to cherish her memories and lessons for the rest of her life. They then reveal their hard worked treat they made for her, and share a big group photo before they go outside to see her off.

The sun is setting and Akari reveals the banner to say "see you again, Miyabi-chan!". Miyabi is touched by the grand gesture and Akari hands her the Camellia origami she made. She comments that she got the idea from Miyabi's pretty hair ornaments and she thanks Akari for the gift. Akari then tells her that she refuses to say goodbye, because as long as they have their Aikatsu they will see each other again someday. With that Miyabi says one last thing and takes off.

Several days later while on break, Miyabi sits down to watch as Akari puts on a forecast report. She looks at the flower origami that Akari made for her and stands up to observe the bright sky.
