Ruby Rose is the main protagonist of RWBY. She is a former student of Beacon Academy. Her weapon of choice is her High-Caliber Sniper-Scythe known as Crescent Rose. Ever since she was little, Ruby has had a romanticized view of the Huntsman profession. She is quick to reveal she wanted to become a huntress in order to be like the great heroes in fairy tales, and she has described being one as far more "romantic" than being a police officer. Her mentality is described as "I don't have time for my emotions. I've gotta make sure that everybody else is okay." She has also shown a distinct lack of ability picking up social cues due to being a very open and honest person. This results in her being unable to pick up Weiss' sarcasm in the "The Shining Beacon", and struggling to act formally in "It's Brawl in the Family". Although Ruby has no trouble interacting with friends, she does have trouble actually making them, and once admits that seeing new weapons "is like meeting new people, but better".
 
Ruby first appeared in the "Red" Trailer visiting the grave of her deceased mother, Summer Rose. After an invitation from Headmaster Ozpin following an altercation with Roman Torchwick, Ruby attends Beacon Academy in order to become a Huntress. During her time at Beacon, she is the leader of Team RWBY, consisting of Weiss Schnee, Blake Belladonna and her half-sister, Yang Xiao Long. However, following the Fall of Beacon, Ruby travels to Haven as a member of Team RNJR until Team RWBY's reunion at Haven Academy.
