This symbol is used in three places:
- on the forte of her sword blade,
- on the throat of her uniform,
- on a Black Card, which is kept rolled-up inside the sword hilt.
When a Claymore discovers herself in danger of awakening, she sends her card to another Claymore, usually a trusted friend. The recipient rendezvous with the sender at a private locale. Then, the recipient euthanizes the sender.
Being presented with the Black Card of another Claymore is normally a sign of great respect and trust between them, as Elena does as she and Clare comforted each other during their painful transformation into Claymores. It can however be a lure to a trap, as Rosemary did to kill Teresa from her jealousy.

- Rosemary: Her Black Card is sent to Teresa as a trap to lure her to Godahl Plateau and attempts to kill her after Awakening.
- Hilda: Her Black Card is sent to Miria via Ophelia. However, Ophelia destroys it and condemns Hilda to become an Awakened Being (Extra Scene 2).
