Yume Nijino

"Absolutely, I'm going to be the top star among the idols! Yume Nijino! Is about to start her Aikatsu!"

- Yume Nijino in opening intro S2

Yume Nijino (虹野ゆめ) is the main protagonist of the Aikatsu Stars! series. She is a member of S4, a student at Four Star Academy and belongs in the Flower Song Class. Yume is a cute type idol, whose preferred brand is her self-created brand, Berry Parfait.

Appearance
Yume is a fair skinned girl, with eyes of red, orange, and yellow. Her blonde hair has ombre coloring, turning pink towards the ends. She wears her hair in knotted, curled pigtails with matching forelocks and corner parted bangs and is almost always seen with her pink trademark ribbon worn on the left of her head. As a Four Star Academy student, she wears the standard uniform.

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

Personality
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. 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 gives up on her dream of joining S4.

Background
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 to Hime in the hospital wing.

Relationships

 * Laura Sakuraba
 * 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. That was how they first met.


 * Koharu Nanakura
 * 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.


 * Hime Shiratori
 * 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.


 * Subaru Yūki
 * Yume often meets up with him, but not intentionally. He calls Yume a "Boiled Octopus", much to her aggravation. 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.


 * Mahiru Kasumi
 * 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.


 * Ako Saotome
 * 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.


 * Yuzu Nikaidō
 * Yume's fellow Yuzukoshō member and later her fellow S4 member.


 * Elza Forte
 * Yume was scouted by Elza as the next new member of her idol school, Venus Ark. Yume sees Elza as a greatly talented person.
