A: Sango is a teenage demon slayer, from the village of demon slayers. She uses a giant boomerang, Hiraikotsu, to kill the demons. She is accompanied by the demon cat Kirara, who accompanies Sango into battle.
While on a mission to kill an evil demon, the possessed lord of the castle controlled Kohaku, Sango's brother, and uses him to kill Sango's family and companions. Sango escapes and realizes that the lord is possessed. However, both Kohaku and Sango are attacked by the lord's retainers and are buried upon the lord's son, Kagewaki Hitomi, who is actually Naraku, an evil hanyo. Naraku tricks Sango into killing Inuyasha by telling her he's the one responsible for her village's destruction. When that fails, Naraku revives Kohaku, and makes use of him to control Sango's emotions. Although Sango seeks revenge against Naraku for the destruction he caused to her life, the main thing she wants to do is rescue Kohaku from Naraku's influence.
