Hero Overview
~ Ruby Kurosawa

Ruby Kurosawa is one of the nine main characters of Love Live! Sunshine!!. She is a first-year in Uranohoshi Girls' High School. Her image color is magenta. She is a member of CYaRon!, a sub-unit under Aqours. She is also the younger sister of Dia Kurosawa.

She is voiced by Ai Furihata in the Japanese version of the anime, and by Sarah Wiedenheft in the English version of the anime.


Ruby is a first year student who is the younger sister of Dia, who she shares a strong bond with. She is from an old family involved in fishing management whose name is well-known around the area. The Kurosawa family also owns a number of companies including real estate, entertainment, human resources and restaurant management. Ruby is almost always nearby her best friend, Hanamaru Kunikida.

In the anime, in the first episode, Ruby is shown to display a big interest for school idols. Season 1 Episode 4 shows that she used to be a fan of school idols, sharing this hobby with Dia, although something caused her older sister to seemingly lose that interest, which is revealed in Season 1 Episode 6, Episode 8 and Episode 9 to be Dia's failure as a school idol. Ruby's love for school idols remained intact, but the event made her secretly keep it away from her sister. She later joins Aqours in Season 1 Episode 4, after counting with her sister's support.


Ruby is a very shy and polite girl, which makes it hard for her to get along with other people. She has a tendency to utter or scream "Pigii!!!" when she doesn't like something; in the event she screams, her face will turn red as she does so. She has never talked to any males besides her father before, so she has always been bad at dealing with the male gender. Although she is fearful and easily upset, she does has a tough interior forged by her role as the daughter of a rich, well-known family.

From a different perspective, Ruby is adaptable and mostly admired by her friends, and they support her no matter what. Her catchphrase is "Ganbarubii!" (がんばルビィ!lit. "Rubesty"), a portmanteau between "ganbaru" (頑張る try with full effort) and her own name; she uses this phrase to encourage herself or others to do their very best. Ruby also refers to herself in the third person from time to time, just like Hanamaru.

Due to the strong bond she shares with her sister Dia, Ruby will immediately display her tough interior and defend her sister when a negative point of her is brought up, as seen in Season 2 Episode 8. Ruby is also shown to be playful and teasing when she teases Yoshiko's Fallen Angel behavior and her embarrassing moments (alongside Hanamaru), which annoys Yoshiko all the time. She also despises spicy food.
