Shirosora Diamond is a main charater of Sky Pretty Cure: The Unofficial 5th Season. Having her first year in university, Diamond does her best to come closer to her dream.
Having her first year in university, Diamond does her best to come closer to her dream. She even helps other students with studying when they don't understand something. She usually gets told that she's great at explaining and would be a great teacher. But studying isn't the only thing she does, she also got quite braver and tells others when she doesn't like something. Diamond doesn't just try to stay in contact with her friends, she also does her best that everyone else stays in good contact with them.
Shirosora (白空?) - Shirosora comes from Shiro (白?) meaning "white", "snowy", "bright" or "clear", combined with Sora (空?) 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".
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". However, it can also mean "invincible, untamed". The diamond is also the birthstone of April.
