Kirara

was Sango's faithful nekomata companion and Sango's main method of transportation.

Kirara usually appears to be a small kitten-sized feline with two tails. However, she has two forms: one of a small kitten, and one of a large cat resembling a saber-toothed tiger. In her full-sized demon form, flames emerge from her feet and tails and her abilities increase tenfold allowing her to battle even the strongest of Demon opponents.

Kirara is shown to be very intelligent as well as sentient. She's fiercely loyal to Sango (due to their long past) but with time she shows loyalty to all members of the group.

Kirara demonstrates exceptional patience, often honoring the requests of the group and their various friends. For example, it is revealed that she allowed Inuyasha to practice the potentially lethal windscar attack on her leaving bald spots on her fur. In addition, she also helped Miroku impress village women and ward off the undesired advances of the older village women. Kagome admits to playing dress up with her, and using her to return to the modern age without the knowledge of the rest of the group. She is also particularly close to Shippō, who are often seen playing together. This is probably because of their connections as being demons, and also because they are still young.

Three years after Naraku's defeat, Kilala joins Kohaku as he trains to become a demon slayer. Meanwhile, Sango is starting her new life and family with Miroku and their children.

Although she is currently Sango and Kohaku's pet, she was originally the companion of Midoriko, the miko who created the Shikon no Tama, suggesting that she's far older than she seems. Since Kirara is a cat demon, she acts similar to regular cats: eating cat food, treats, fish, and playing with cat toys. She also has cat-like weaknesses too.
