Both contain two strong female protagonists with a strong bond, are highly skilled for combat fighting (high action), end up fighting against one another, and they're both pretty gory animes. Kagura also closely resembles one of the main female characters in Noir Certain tracks/songs are also similar with the siren-like voices.
