Inuyasha

The namesake of the series, Inuyasha is an angsty half demon. The product of a union between his human mother Izayoi and his Demon Lord father Inutaisho*, his father is killed while he is resurrecting and rescuing Izayoi and infant Inuyasha from Setsunano Takemaru. There's very little canon information available that I've seen about Inuyasha's childhood other than the nebulous description of it being "Unpleasant" and that he was shunned by both demons and humans alike. There are apparently portions of the manga that show him and Sesshoumaru growing up together and getting along well, but I haven't seen them. Probably because I haven't read the manga ;;(^o^);;. Anyway, I'll make a trip to the comic shop and fix that soon and let you know what I find.

Fast forward to a grown up Inuyasha. Embittered with the way life's treating him, Inuyasha decides he'll do whatever it takes to become a full-fledged demon. His search for the Shikon Jewel puts him in the path of Kikyo, who rather than kill him, disables him by pinning him to a tree with her arrows. She continues to kill demons that come to the area looking for the Shikon Jewels and Inuyasha hangs around the area and hides in the shrubbery. Kikyo kept talking to him even though he was concealed and eventually they would come to have longer conversations, and later fall in love.

Eventually they decided to use the Shikon Jewel to make Inuyasha fully human and since the jewel would be gone, Kikyo would no longer have to guard it and she'd be free to live with Inuyasha. Having talked it over the two agreed to meet the next day and Kikyo would bring the jewel for Inuyasha.

Unfortunately, a crippled bandit named Onigumo who Kikyo had been caring for was lusted after her and wanted to corrupt her and the jewel. He made a deal with a bunch of demons to give them his body to devour in exchange for a new body with which to corrupt Kikyo and the Jewel. The demons ate his old body and formed themselves into a new one for him. The result was the demon Naraku.

Naraku changed his shape to take the form of Inuyasha and attacked Kikyo. Mortally wounding her, he taunted her by saying it was all an act to get the Shikon Jewel and that he never loved he. He took the Jewel from her and returned it to the shrine before starting the second part of his plan. That taken care of, he then attacked Inuyasha while in the form of Kikyo. Angered, Inuyasha went to the shrine and took the jewel. While he was escaping, the real Kikyo found him and pinned him to a tree with an arrow just before she died.

He stayed pinned to the tree for fifty years, unconscious. Kagome revives him in the first episode to save her from Lady Centipede. After Lady Centipede's defeat the then turns on Kagome to get the Shikon Jewel, but is put under control by a magic rosary that Kaede put around his neck. Whenever Inuyasha acted up, all Kagome has to do is tell him to sit and it plants him face-first onto the ground.
