Sailortinnyanko
Sailortinnyanko appears right before Siren's death. She pointed out all of the failures that Siren had done, so it is her fault that Siren dies. Crow and Nyanko ALWAYS fought. The kitty fouled up one of Crow's attacks, and accidently threw her in a black hole which killed her. But Galaxia was fed up with Nyanko's failures, and took away her bracelets.
