The Black Knights (黒騎士 Kuro Kishi) are the pseudo-antagonists in Sin, Damnation and the Atonement Girl. They are named after the 7 cardinal sins, missing only one name.

Overview
The Black Knights are 6 mysterious figures who reside and protect the crystal imprisoning Lisette Vertorre within Red Night. They call the protagonists 'Fragments' and try to kill them for unknown reasons. It is later revealed that they are a group of Index's apostles called the Punishment Squad who sealed away a witch called Lieselotte Werckmeister 64 years prior to the events of the story with the price of their own lives, while Lisette is, in fact, an amnesiac Lieselotte. In order to protect the seal from being broken, Superbia, the only survivor used her soul binding art to bind the souls of others into the bodies of the Larvaes inside Red Night after the battle.

In the anime, however, the Black Knights' forms are the result of the spell they used to seal Lieselotte.

Avaritia

 * Main article: Avaritia

The leader of the Black Knights and determined to crush the "Fragments". In actual, he is one of the 14 saints from Index, called Georgius of the Rainbow. He was sent out with his subordinates to eliminate Index top priority threat, Lieselotte Werckmeister. After a seemingly losing battle with Lieselotte at Ayame Hill 64 years ago, he used his last resort, the forbidden technique, Contract of the Rainbow to split Lieselotte's soul and the piece of Emerald Tablet within her into seven fragments to weaken her. Lieselotte with one of the fragments remains in her body was sealed within the crystal. The other fragments, due to the technique, was scattered across six parallel worlds. This explain why he calls the gang "Fragments" because their bodies contain those "fragments" and those "fragments" are the sources of their powers. In his past mission, he sealed a dragon within his body with the same technique and release it in the final battle to crush the "Fragments" and Lieselotte with the price of losing himself. It took a lot out of him to maintain seal of the dragon within his body and at the same time Lieselotte's seal.
