In Jewelpet Sunshine, Ruby has a more similar personality to her first series' counterpart, but with a bit of an edge to her because of her difficult relationship with Kanon.

In Jewelpet Kira☆Deco!, Ruby owns the Kira-Kira Shop where she keeps all her prized jewels, and also where she lets Pink stay in while acquiring the Deco Stones.

In Lady Jewelpet, Ruby is very air-headed and doesn't really know how to teach Momona the right things. She can't tell when someone is insulting her and takes it as a compliment instead.

In Jewelpet Attack Chance!?, Ruby has a lazy attitude who doesn't like to get things done. She also has a huge appetite for food than she does in the first series.


In Ruby's official setting in the franchise, she represents Luck. As the Jewelpet of Luck, Ruby's magic can enhance one's luck. In Jewelpet and Jewelpet Twinkle☆, she has the power of Courage, which allows humans to become courageous and work up their courage to do something extraordinary.

In Jewelpet, Ruby is ranked in the Acrylic Class because of her magic, which has a 1% success rate and can cause bad luck and explosions if it fails. However, its reliability is varied; even after Ruby had been upgraded to Super Crystal Class by learning a new lesson of courage and had been trained with Labra to temporarily upgrade her magic in order to summon Opal, her magic still causes explosions. Ruby can also use the Jewel Pocketbook alongside Rinko to awaken Jewelpets from their charm forms.
