Inuyasha is a half demon that despises humans for the death of his human mother. Ever since then his heart has been ice since he was a child. He's been getting stronger as a fighter since his father is the leader of a dog demon tribe. He fights for his life day after day.
The only thing he has to remember his mother is a cursed necklace that is to stop him from killing humans. If a human fears him or starts to cry he'll feel his life being strangled. The only way for it to be removed is if he learns to love a human and to be loved in returned than and only than is when the necklace will be removed. Now we see a man in his early 20's with long silver hair silver dog ears gold eye's wearing dark red kimono walking around a camp.
Then all of a sudden there was a voice yelling "INUYASHA!!Inuyasha turned around to see a man with long silver hair up in a high ponytail wearing a white kimono with armor charging at him with his claws. Then the man slashed at Inuyasha but missed and Inuyasha's foot landed on the back of his neck and said "you have to do better than that old man."
The man laughed and said "yeah you're right well I guess I taught you too well." Then Inuyasha left to the woods. When he was in the woods he was thinking "it's been 20 years since mother died and that she gave me this necklace so I couldn't kill humans ha that's a laugh she said that it will teach me to like humans. She must have had her reasons."
Then he found a girl with long black hair wearing a strange green kimono. He walked up to her to see if she was still alive. She was still alive he wondered how she got into the dog demon's forest but the rules of the forest is that if an intruder comes to the forest than they are a prisoner until their fate is sealed. Then he picked up the girl and carried her in his arms and carried her to his camp.
