Sesshomaru comes to the Netherworld and engages in combat against Naraku. Hosenki challenges InuYasha to slay him in order to strengthen the Tetsusaiga and acquire the power to fight back against Naraku. Every time Sesshomaru slices the body of Naraku, his poisonous miasma affects everyone. InuYasha must choose between eradicating the miasma and slaying Hosenki. It is then that Hosenski realizes that InuYasha is selfless, giving him the power of the Adamant Barrage to shatter Naraku's barrier. Kagome uses Kikyo's special arrow that forces Naraku to appear through Hakudoshi, being injured in the process and relinquishing the last shard of the Shikon Jewel.
