Kuroro

is Koume's twin-tailed cat demon pet, mistaken for Kirara, who protected her newborn kittens after her mate's death from humans and Tesso who framed her as a evil being. Unlike Kirara, she doesn't appear to be able to transform, and fights the rat demons in her kitten like form. Kuroro was cast out from the village she lived in because Tesso, the rat demon had called her an Omen and convinced the villagers to cast her out of the village, giving Tesso the ability to try and take over the village with an army of rats at his side. She was later allowed back into the village once the fight with Tesso had finished. At the end of the Episode she was shown with Koume being fed by her until needing to go back to her kittens.
