Hero Overview
Yume Nijino, ready to go!
~ Yume before her performance

Yume Nijino (虹野ゆめ) is the main protagonist of the Aikatsu Stars! series. She is a student at Four Star Academy of the Flower Song Class and is a member of the 26th and 27th generation of S4. Yume is a cute-type idol whose preferred brand is her self-created brand, Rainbow Berry Parfait (previously Berry Parfait). She formerly attended Venus Ark as an exchange student.



Yume is a fair-skinned girl with gradient orange eyes. She has long blonde hair with a pink ombre coloring towards the end, and is tied into curled pigtails, its tie-off section wrapped with hair. She also has forelocks and parted bangs, and is often seen with her pink ribbon worn on her left-side.

In Season 2, Yume's hair has grown longer and wavier, with an increase in pink ombre at her hair's ends. Her pigtails are now tied higher from the back of her head. As a student at Four Star Academy and a member of S4, she wears a specialized uniform for the S4 members.


Yume is known to be cheerful and full of curiosity but cries easily when touched. She is also a person with a strong will and can be impulsive with a mischievous streak. She wants everyone will be happy of her song. At times she can be bold but is slightly oblivious and gets embarrassed really easily. She never gives up no matter what happens and is always determined to help her friends or those she cares about. When Koharu moved to Italy, she volunteered to put on a show for her so that Koharu wouldn't be sad about leaving. She also never gave up on her dream of joining S4, and when she did it, she felt as if she had to work harder, as she said in Episode 51.


Yume highly adores the unit group S4, and was said to be an owner of hidden talent. She highly admires Hime Shiratori and strives to be like her.

Yume grew up with her parents in their confectionery shop. She was also previously on the volleyball team at her school before entering Four Star Academy. During her entrance performance, Yume created a powerful rainbow aura which made her perform above average. After the performance, she fainted and woke up next to Hime in the hospital wing.


The very first friend Yume made at Four Star Academy. Yume considers Laura to be a precious friend and rival, and as such wants to help and support her as much as she can. They first met when Laura was late for class and asked Yume to open the window that was next to her because Laura was outside.
Yume's childhood friend who of which she applied to Four Star with. Despite being in different classes, the two appear to be very close and were roommates until Koharu had to move to Italy.
She admires Hime and longs to someday join her on stage. Hime also helps Yume understand her mysterious power and helped her overcome it when it's needed.
Yume often meets up with him, but not intentionally. He calls Yume a "Boiled Octopus" due to her tendency to turn red when angry, which agitates her. Subaru often gives her a point in the right direction, but Yume has a short temper with him. However, she seems to be on friendly terms with him and is comfortable around him. In Episode 43, Yume declares Subaru as her rival, which he later reciprocates in Episode 50.
They first become acquainted after Yume offers her a tanzaku for Mahiru to write down her wish. With the help of Laura and Koharu, she bakes Mahiru a chocolate cake for her performance, helping Mahiru remember the importance of a smile and actively supporting Mahiru with her goal of defeating Yozora. Mahiru later becomes Yume's fellow S4 member.
Yume's fellow Yuzukoshō member and later her fellow S4 member. Since Ako gets too embarrassed to talk to Subaru, Yume often gets involved and ends up talking to him instead. Ako thinks of Yume as her 'love rival', because Yume tends to talk to Subaru a lot and it makes Ako jealous. However, they are good friends.
Yume's fellow Yuzukoshō member and later her fellow S4 member.
They get to know each other when they end up in the infirmary, where they discuss overcoming personal limitations in order to achieve their dreams. As they both aim to become a part of S4, Lilie acknowledges Yume as both a friend and a rival and hopes that they can push each other to greater heights.
Yume was scouted by Elza as the next new member of her idol school, Venus Ark. Yume sees Elza as a greatly talented person.
Yume mentors Aria on Hime's request. She finds her to be a mysterious person and her nature to be amusing.

I have friends who support me, a rival to fight alongside me, and a senpai who always lights my path. Everyone believes in me, so I'll believe in myself too!

Absolutely, I'm going to be the top star among all idols! Yume Nijino! Starting her Aikatsu!
~ Yume Nijino in Season 2's intro
I just remembered. That sparkling feeling I got when I first wore a dress as an idol. It felt like there was so much more I could be. That I could shine from deep inside my heart! My most precious feelings. I want not just me, but everyone else to shine as brightly as they can. Berry Parfait is meant to bring out the best and brightest in everyone.
~ Yume to Koharu
I'm so glad all of the audience left with big smiles. My feelings got across to them, and that made me happy. Even if I haven't reached the level of getting Wings of Stars yet, I still feel like I've gained something important. I can't contain my excitement realizing that there's so much more I can do!
~ Yume after her performance with her first Premium Rare Dress
Even if you leave Venus Ark, it's not over. So long as you have a dream... As long as you have fans supporting you, you can't let it end!
~ Yume to Alice
Today, I was filled with power while watching how luminously the other girls glowed. Thanks to them, my heart is filled with radiance! That's why I choose to come out in my everyday clothes. So that you could see my pure brilliance as clearly as possible.
~ Yume at Everyone Shine! Dream Idol Audition
I want all of us idols to become the bright light that can make the hearts of everyone around us shine.
