Background
Born as the younger sister of Dia Kurosawa, Ruby was often seen as a burden by her father due to her coward personality (and also that she was the cause of her and Dia's mother's death).

In Episode 12, AquaPink fights against Silver Ninja Youkai, who becomes Rukia after her defeat. Then in Episode 13, Ruby renames the cold-hearted Rukia to Leah Kazuno. She gets teased by Hanamaru and Yoshiko about having feelings for Leah, causing Dia to exclaim that she (Ruby) is too young for love.

In Episode 22, Ruby gets in a middle of an argument between Dia and their father. When AquaRed goes to fight Devil Swordsman Razure alone, Ruby convinced her father that Dia worked hard to honor the family. With that, the Kurosawa family has been reunited.

With that, Super AquaPink, Super AquaBlack, Super AquaYellow and Saint SnowMoon defeat Demon Underling and once more with the Doubutsu Gattai Naga-Oh Stag.

In Episode 35, Ruby and Dia fight, causing Ruby to run away. She then meets with Leah, who also got into a fight with Sarah.

They later get kidnapped by Demon Sisters: Yin and Yang. Ruby tearfully begs Dia to save and that she needs her. While under captive, Ruby and Leah create a plan to combine the Doubutsu Gattai Wild Aqours-Oh with the Konchu Gattai Saint Snow Shinobi-Oh. When the Demon Sisters get larged, Super AquaPink tells Super AquaOrange and Saint SnowGold to combine all 11 animal mechas to form the Doubutsu Dai Gattai Saint Aqours Snow Kami. With that, Ruby and Dia reconcile with the latter complimenting that Ruby has been gaining more confidence than before.

In the final battle, Ruby, Yoshiko, Hanamaru and Leah face against a revived Demon Underling. During the battle, AquaPink confessed to Saint SnowMoon that she loves her, which the latter replies that she does as well. Ruby then comforts Leah, after the latter learned from Dia that Sarah has died.
