Kurohime's Crows

are the characteristic summon of Kurohime Kōgōyasha. At a young age, Kurohime made a contract with crows which allows her to summon them as she wishes. She mainly uses them combined with her ninjutsu while fighting — often de-materialising into a flock of crows or summoning them to blind her target. She also uses a variation of the Clone Technique called the Crow Clone Technique where she uses her crows as a medium to create a copy of herself which when hit, disperses back into crows.

Unlike regular crow summons, Koruhime's crows are all in possession of the Rinnegan, as a result linking their line of sight with her own. Their genetics tampered with by the medical-nin, they are capable of exhaling poison, or exploding into toxic clouds, both of which when inhaled result in one's death. While although Koruhime is capable of channeling the powers of the Rinnegan inside of them, such as the Deva Path to produce lesser effects of the original (technique(s)), they aren't without appropriate drawbacks, leading her to be hesitant in using this ability irrationally.
