What is a Fanlisting?

About Sango, Kirara and their relationship

Sango is a highly skilled youkai exterminator, or demon slayer, and a member of a group of exterminators trained to kill demons. Sango, like all other children of her village, started training to master the art of youkai extermination from a very young age. Her preferred weapon is a huge boomerang called the Hiraikotsu, and is made of the bones of youkai.

Kirara is Sango's faithful, demon-cat companion. Kirara usually appears in the form of a small feline no larger than a kitten with two tails. When necessary, she can transform into full demon with larger saber-teeth, flames around her feet and tail, and at a size large enough to carry 2-3 humans on her back. In her full demon mode, Kirara is capable of flying, an ability InuYasha's group find useful for transporting Sango, Miroku, and Shippo when InuYasha is running quickly or jumping to greater heights than they would normally be able to keep up with. For most of the series, Kirara stays primarily with Sango and aids InuYasha's group in battles.
