inuyasha,Kagome,Shippo,Miroku,Sango,and Kirrara are walking to Narakus wanished castle.They all looked around and saw no clue of where Narakus castle is now.But Sango saw something that she had thought that she wouldnt ever se again it was a part of her fathers armor.She toold Inuyasha and the others that this was the place that her father and the rest of the demon extirminators were killed.After Inuyasha and the others left we saw Kohaku Sango's little brother who was also killed by Naraku's castle.He was in a village where two elders lived in.Kohaku was slicing wood in half for the elders.And he got something good to eat,and they talked about who Kohaku is.But Kohaku forgot everything even Sango and Naraku.The grandma fought that Kohaku came from the castle where Naraku the fake lord lived in and then Kohaku finaly remembered that he did live there.Kohaku didn't even remeber his own name.But then Kohaku sensed that there were demons coming to get the sacred jewel inveted in Kohakus back that Naraku put,Kohaku didn't know that there was a jewel in his back.He said goodbye to the elders and left because he din't want them to get hurt.Kohaku ran as fast as he could and then Sango saved him right before he was hit by one of the demons.Sango was surprised to se her little brother alright but Kohaku didn't even know who she was.So they finshed the demons of and left to a safe spot so the sacred jewel doesnt get taken.Sango talked to Kohaku and asked him some questions,Kohaku couldnt remember anything except Naraku saying to him that he doesnt need him anymore.That happend when he was running away from the demons,and he also remembered his name.Then Kohaku fell asleep and Sango went outside and Inuyasha was coming right at her.He was talking to her about Kohaku if it was just a trap set up by Naraku again.Then the demons came again,and Kagura came with them also she knew that this was a trap setup by Naraku to kill Kagome.Kohaku ran away so that Sango and the others wouldn't get hurt.So sango and Kagome went to find him.Kohaku was running away from the demons again and Sango and Kagome saved him.Sango toold Kagome to take Kohaku and run to a safe spot and they did.while Sango was fighting the demons.Inuyasha and Miroku were also batteling demons and Kagura.Lots of them were coming by miroku even poison insects,but Miroku sucked them in with his wind tunnel for Sango.Shippo was hiding some place safe.Mean while Kagome and Kohaku were talking and Kohaku returned to him evil self again and tried to kill Kagome.Kagome screamed realy loud so that Sango and Inuyasha heard her and were coming to her rescuse.
