General Information


"You might not seem like it, but you are pretty energetic and always cheering. You actually seem more like the calm person."— Loo describing Diamond's character in episode 15

Diamond is a smart and very gentle girl. She is sometimes referred as Queen by others due to the fact that she is one of the smartest students at her age. Diamond is quite calm that's why people would describe her as shy, which is wrong. She is quite opened and has her own mind. However she has good manners and would never say anything that would offend others. Despite her calm, kind and gentle personality, she is also very passionate and energetic. Diamond always follows the "voice of her heart"; she does the things she thinks are right instead of what people want her to believe.


Main article: Shirosora Diamond / Relationships


Shirosora (白空?) - Shirosora comes from Shiro (?) meaning "white", "snowy", "bright" or "clear", combined with Sora (?) meaning "sky" or "air". So combined, Shirosora means "white sky", "bright sky" or "snowy sky". 空 can also be a synonyme for 天, which means "heaven" in Japanese. If 空 and 天 are combined, they mean "sky", "air", "firmament" or "ether". All together, they are a pun to the series' main theme, which is the sky after all.

Diamond (ダイヤモンド?) - Diamond is named after the precious gemstone diamond with the same name. The word comes from Old French "diamant", which orignated from Medieval Latin "diamantem" and Vulgar Latin "adiamanten", altered by influence of the many Greek words in dia. The original word comes from Latin meaning "the hardest metal".[4] However, it can also mean "invincible, untamed". The diamond is also the birthstone of April.

Cure Whitney - Her Cure alias is based on the given name and surname Whitney, which was originally derived from a place name meaning "white island" in Old English.[5]

Dia Card (ダイヤカード?) - Diamond's name in Emerald's Adventures in Wonderland. Playing one of the 'Card Guards', Diamond got the name based on the card suit Diamond, which is also her name.


Dia (ダイヤ?) - A short version of the word Diamond, which is her actual given name. Diamond is called that way by FairySina because she likes to shorten "long" words. However in the series, Dia is mostly used by Low, who infact only calls her "Dia".
