Black Glass

Black Glass is the femslash ship between Cinder Fall and Blake Belladonna from the RWBY fandom.

Canon
Blake and Cinder technically met in volume 2 of rwby. In volume 3 when Cinder revealed to everyone on live television that she was behind Penny's death, Blake can be seen looking at a tv screen visibly angry. She then proceeds to go back to Beacon and fight against Adam, who has teamed up with Cinder. Later in volume 5, the newly reformed white fang comes to help ruby's team and fight against Adam and Cinder's faction. The two then don't see each other face to face until volume 8.

It has been noted that Cinder and Blake have many similarities. Firstly, they both had abusive pasts, Blake with Adam and Cinder with her stepmother. Secondly, they both have short black hair. Thirdly, they both have amber colored eyes. Then lastly, black seems to be both of their main theme colors.

When Cinder shows up infront of team rwby she immediately starts antagonizing them. Blake prepares herself to fight. Later when Neo "kills" Yang, Blake is devastated and starts crying. She then proceeds to fight Neo. Later when Cinder is giving another monologue Blake comes out of nowhere and angrily kicks her in the face, which sends Cinder flying backwards. Blake is then later shown fighting against Cinder alongside Penny and Weiss.

Fanon
Black Glass is a rarepair in the rwby fandom, this is mainly because the two never "interacted" onscreen until volume 8. There were some fans that theorized that the two might have even been related since they looked so similar. There are even some fans who refer to them as the "disney princess pair" because the two are based off of Cinderella and Belle from Beauty and the Beast. Many fans were extremely satisfied when Blake kicked Cinder in the head in volume 8. It has a small fanbase on tumblr.
