RWBY (pronounced "Ruby") is an American anime-styled animated web series and media franchise created by Monty Oum for Rooster Teeth. It is set in the fictional world of Remnant, where young people train to become warriors (called "Huntsmen" and "Huntresses") to protect their world from monsters called Grimm. The name RWBY is derived from the four main characters' forenames: Ruby, Weiss, Blake and Yang, as well as their associated theme colors; Red, White, Black and Yellow, and their combined team name: team RWBY. Following several promotional trailers, the first episode was screened at the Rooster Teeth convention event RTX and then released on their website in July 2013. Subsequent episodes were released approximately weekly, first to Rooster Teeth's subscribers and then to YouTube a week later. The series became a viral hit, and a second season, subtitled Volume 2,  was released in July 2014.
