Kirara
Sango's devoted nekomata companion and primary mode of transportation is Kirara. Kirara was Kohaku's traveling companion after Naraku and the Sacred Jewel were destroyed. She is Setsuna's half-demon companion in Hany no Yashahime and the partner of Sango's youngest child, Hisui.
Kirara typically has the appearance of a cute adult-sized cat with a kitten's body type. She has two fluffy tails with two stripes on each one, black paws with a stripe, black pointed ears, diamond-shaped marking on her forehead, and light yellow fur. Her eyes are black with red sclera. She did, however, manifest in two different ways: as a cat and a larger form that resembled a saber-toothed cat.
Kirara is a nekomata, a cat with two tails that can change its shape, and is another kind of yokai. She doesn't behave like the demon that she is said to be. She stands by the side of demon slayer Sango and her brother Kohaku as they attempt to ward off bad things, rather than terrorizing people. Her fidelity endures. She comes dangerously close to giving her life to save Kohaku, who has been poisoned by the half-demon she is trying to kill for him. Don't be fooled by her adorable appearance and undervalue her abilities. Kirara may transform into a ferocious, gigantic cat if necessary.
