Sesshomaru visits one of his father's old friends Bokusenou, who is a tree that limbs were used to make Tetsusaiga's scabbard sheath. Thus is why the sheath is so powerful. He explains to Sesshomaru that each time Inuyasha transforms and the youkai blood takes over, he loses control of himself as well as his thoughts. Inuyasha will not be able to maintain his cool during a fight when his life is threatened, like a full youkai would. In a hanyou, the youkai blood wills to live and eventually Inuyasha will cease to exist. He explains that Tetsusaiga is a guardian sword given to Inuyasha by his father in order to keep Inuyasha's youkai blood at bay. Meanwhile, Inuyasha runs to the aid of a boy and his grandfather. Inuyasha is dissapointed that the old man just needed help with a sprained ankle, but he carries him to the nearest village. After returning to their journey, Inuyasha suddenly stops, smelling human blood. The gang then notices smoke coming from the village they had just dropped the boy and his grandfather off at. The boy then comes running toward them and collapses on the ground injured. Inuyasha and Miroku race ahead while Kagome and the others tend to the boy's wounds. Upon entering the village, they encounter a mass of thieves raiding the village and killing people. Inuyasha tells the thieves that hell will take care of them later, he then demands to see the boss. Coming out of the group of thieves on a white horse is the boss. Inuyasha smells that he is a youkai. Inuyasha confronts him as being a youkai leading a band of thieves. The thieves look around with surprised looks. The boss youkai takes a great interest in Inuyasha's sword. He then says that it will be his. The boss attacks Inuyasha with a giant ax. Inuyasha blocks the hit with the heavy Tetsusaiga, breaking the ax. The boss becomes even more impressed with the sword. The boss grabs a woman to use as a shield against Inuyasha. The boss then spits poisonous venom at Inuyasha, hitting him in the cheek. He then slices Inuyasha in the chest with another ax. Poison begins seeping in Inuyasha's wounds. Inuyasha lunges at the boss several times. Inuyasha drops Tetsusaiga when venom is spit on his hands. Miroku runs to Inuyasha's aid and they both get ensnared into a web on venom. Miroku manages to create a barrier protecting them from the venomous web all around them. The boss attempts to pick up Tetsusaiga, but of course can't, because of Tetsusaiga's barrier. The boss then let's one of his human followers have it since it is useless to him. Waiting for Inuyasha and Miroku to be consumed by the web, the boss begins to feed upon the women in the village. With the venom seeping more through his wounds and throughout his body, Inuyasha begins to become more and more angry. His heart starts pounding. Thump, thump. His eyes flicker red.............
