General Information


Rubi is a young and energetic girl. She is very athletic and a good team player. Currently, Rubi is the captain of her school’s basketball team. She has a strong will and always tries to do her best. She would never just drop something just she got bored by it or she doesn’t want to do anything anymore. She is a hard working girl, who can also be very lazy. Her laziness is usually shown when it comes to school work that has nothing to do with sport or helping at her parents’ restaurant. She usually gives her duties at the Feather Bell to her younger twin sister Robin. Adding to that, Rubi mixes up things which makes others think that has no idea what she’s actually doing. But that is not correct.


Akabayashi (赤林?) - Akabayashi comes from Aka (?) meaning "red", "crimson" or "scarlet", combined with Bayashi (?) meaning "forest" or "woods". So Akabayashi means "red forest". "Red" could be a reference to Guardian Angel Crimson, her alter ego, who holds the power of the red colored rainbow.

Rubi (瑠美衣?) - Rubi, actually written as Rubii, comes from Ru (?) meaning "lapis lazuli" or "beryl", combined with Bi (?) meaning "beauty" and I (?) meaning "clothes" or "garment​".[3] The precious stone Ruby can also be seen as the symbol of passion.

Yamane Rubi (ヤマネ・ルビー?): Rubi's name in Alice's world. The name is playing with the Japanese word Yamane (ヤマネ?) meaning dormouse and her real name. The dormouse is a character in Alice's Adventures in Wonderland.


Rubs: The name actually comes from Rubik's Cube, which she kept spelling "Rubix" in her mind. So she switched the initials and it became Cubix Rube until it finally turned into Rubix Rub(e). That that's where the name Rub/Rubs comes from.
