You know, it's funny. Some of the characters in CCC seem somewhat similar to BRS. BB has that long coat of hers, Melt Lilith has those mechanical limbs, Passion Lip has those massive claw/hands. Oh, and CCC Lancer has demonic horns and features, similar to some BRS characters.
Why is this funny? Well, I was bored and was looking up CCC on Wikipedia. According to Wikipedia, a doujin artist named Huke did the weapons design for CCC. And BRS was drawn by a guy who goes by 'Huke'.
Coincidence? Maybe. But if they are one and the same? Awesome.
