Inuyasha wasn’t always alone, as a child. At one time he had a friend who accepted him, as a half demon. She was human, and even more importantly the headmaster’s daughter. She was named Sinister after the skull marking that appeared on her arm when she was born. A few years after Izayoi, Inuyasha’s Mother, passed away, Inuyasha was forced to flee the village he once lived in, leaving his child-hood lover behind. Now Inuyasha unexpectedly runs into Sinister 63 years later, and learns she also has been under a spell. Sinister has a completely unexpected future that no one saw coming, not even Inuyasha.
