Kuroro

was 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 an evil being. Unlike Kirara, she doesn't appear to be able to transform, and fought 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 being fed by Koume until she needed to go back to her kittens.

Physical description
Kuroro looks just like Kirara aside from the fact that she has black stripes under her eyes, more black markings on the tip of her tails, no stripes on her feet, and the fur around her neck is completely black.
