InuYasha (犬夜叉) is the male protagonist of the series, aged sixteen in appearance and mindset. Born to a dog demon father and human mother, InuYasha is a half-dog demon who initially wants to use the power of the Sacred Shikon Jewel to become a full-blooded demon like his older half-brother, Sesshomaru. Fifty years prior to the main era of the storyline, though, InuYasha fell in love with the priestess Kikyo, who guarded the jewel. InuYasha changed his mind about the jewel, and wanted to use it to become human so he could live with her, but Naraku manipulated both of them into believing they had been betrayed by one another. A shapeshifter, he used Kikyo's form to attack and taunt InuYasha, and InuYasha's form to mortally wound Kikyo. Before she died, however, she shot the real InuYasha with a sacred arrow to seal him to a sacred tree. InuYasha remained in suspended animation for fifty years, until Kagome Higurashi, Kikyo's reincarnation, pulled out the arrow and broke the seal. Later, Kagome shot a sacred arrow at a demon who was escaping with the jewel, which had been hidden in Kagome's body until a demon tore it out. The arrow slew the demon, but it also hit the Shikon Jewel, which shattered. InuYasha and Kagome must then travel together to retrieve its fragments. At first, he is hostile and uncooperative, but Kikyo's sister, Kaede gives Kagome a magical necklace that restrains him by hurling him to the ground whenever Kagome gives the simple command "Sit!" called the Subjugation Beads. Initially wary of Kagome's resemblance to Kikyo, InuYasha grows to trust her as a friend and useful companion. As the series progresses, InuYasha begins to have feelings for Kagome, and at the end of the manga, InuYasha marries Kagome, becoming Sota's brother-in-law.
