Kirara is Sango's nekomata companion—basically a two-tailed cat demon. She normally hangs around in her cute, compact form: a kitten-sized creature with cream-colored fur, black ears, black markings scattered across her body, and those distinctive large red eyes. The two tails are the real giveaway that she's not just some ordinary cat.
But there's way more to Kirara than her adorable appearance suggests. Her true form is a massive saber-toothed tiger-like youkai, which she can shift into when things get serious. It's one of those "don't let the cute exterior fool you" situations.
Sango comes from a mountain village of youkai exterminators, and Kirara has been her faithful companion throughout her work. The dynamic between them is pretty central to Sango's character—Kirara's loyalty and her ability to transform into a powerful beast make her invaluable both as a friend and a fighter.
