Raven Branwen is an anti-hero in Project Yellow. She is the mother of Yang Xiao Long, the twin sister of Qrow Branwen and the former lover of Taiyang Xiao Long.

Qrow calls his sister a dangerous person whose worldview clashes with his own. It is revealed that she has a "survival of the fittest" mentality and, despite having graduated from Beacon Academy as a Huntress, has little issues with taking lives of the innocent or even that of other Huntsmen, indirectly or otherwise. Raven is more serious than her brother and is somewhat demanding, focusing on her mission over family ties. She sees Qrow as a traitor for leaving their tribe. Additionally, Raven is a cynic who claims to foresee Ozpin's failure to protect Beacon from its destruction. She believes that Ozpin is not the man her daughter thinks he is and condemns those who trust him, such as Qrow, Ruby and even Taiyang. Raven's intellect and skill is apparently infamous. Cinder Fall states she has heard numerous stories of her strong and clever reputation. However beneath her "survival of the fittest" philosophy and in spite of her great powers as a Huntress, Raven is a cowardly person.
