Kikyo

"Someone caused my premature demise. Would my murderer's death bring me back to life? The dead have but one wish- to walk among the living once again, a wish that will never be realised."

Kikyo is a character in the anime/manga series ''Inuyasha. ''She is the former keeper of the Shikon Jewel and the priestess of whom Kagome Higurashi is the modern-day reincarnation of. Although she is one of the main supporting protagonists, her moral standing is rather ambiguous for a good portion of the series. Due to the deception carried out by Naraku, she attempts to kill Inuyasha for killing her, but ultimately only seals him to the Sacred Tree for 50 years. After being revived by the witch Urasue, the only thing that keeps her going is her deep hatred of Inuyasha, desiring to pull him into Hell with her. Even after learning that Naraku was the one responsible for her demise, she refuses to forgive Inuyasha and let him seek revenge, believing it to be pointless as it would not bring her back to life. Among trying to drag Inuyasha into Hell with her, she commits several other villainous acts, such as absorbing the souls of women in order to sustain her body, trying to kill Kagome and going so far as to give shards of the Jewel to Naraku.

As the series goes on, however, she becomes more of an anti-hero as the reason for her actions are revealed. She also begins to accept that Kagome is taking her place in the world and that she is Inuyasha's true love. Essentially, she is to Kagome as Sesshomaru is to Inuyasha.
