InuYasha's group returns to Kaede's village to tell her of Kikyo's death. As they talk, she states that Kagome's innate spiritual power was probably sealed by Magatsuhi, the evil will of the Shikon Jewel that did it out of fear of Kagome's enormously strong spiritual powers and abilities. Meanwhile, Naraku enables Magatsuhi to manifest as a demon. With his new body, Magatsuhi attacks Sesshomaru's group to try to take Kohaku's Sacred Jewel shard. Sesshomaru struggles to defend the boy without a weapon and having only one arm. InuYasha's group arrives to find Sesshomaru's right arm badly wounded and Kohaku's shard being defiled. As InuYasha confronts Magatsuhi, he renders Kagome unconscious. Sesshomaru uses his will to heal his wounds, annoyed with InuYasha who is telling him to back down, and assumes his true form to attack Magatsuhi. The brothers struggle to battle Magatsuhi, while protecting their respective groups. Eventually Magatsuhi spears Sesshomaru and traps him, saying he will be come part of Naraku's body. The others fear he is dead, and when InuYasha rushes to free him he is captured as well. Sesshomaru bursts through the ball of appendages, and as Toutousai arrives, Sesshomaru's left arm is restored and he is wielding a new sword. Toutousai calls it Bakusaiga and says it was always inside Sesshomaru, but could not be wielded until he surpassed his father in power and strength and learned to let go of his obsession with Tetsusaiga. With his newfound demon sword called Bakusaiga, Sesshomaru destroys Magatsuhi's body, forcing the latter to flee. At the end of the episode, Kagome finally awakens with a puzzled expression on her face.
