- Black Diamond - Ruriri and Black Diamond act towards eachother like sisters. Not very surprising is that BlaDia cares more for Ruriri than for any of the others. Even though they were created by Break, both Ruriri and BlaDia, will disobey her when needed.
- Ruriri shares her seiyuu with Yukine Chirs from Symphogear.
