The Great Holy Demon Spirit’s Test.Kohaku joins Kikyo, willing to give up his shard if it means killing Naraku, while Koga leaves Ginta and Hakkaku behind because of the increasing danger. Meanwhile, Moryomaru devours the twin demons Kinka and Ginka, obtaining their fire and lightning abilities to strengthen his armor. Sesshomaru attempts to use the Meido Zangetsuha to send some of Moryomaru to the Underworld, but Byakuya interferes on Naraku's orders. Also, Totosai sends Inuyasha and his group to see the demon hermit Yorei-Taisei in mastering his new sword. Upon arriving at his house, they realize that Yorei-Taisei is missing his internal organs, and all the villagers have been turned into the form of demons by an organ thief, who is a real demon blended among the villagers. Yorei-Taisei wraps Tetsusaiga in chains to disallow Inuyasha from drawing it until facing the organ thief. Inuyasha comes across a female serpent demon, and all but Kagome are swept away when trying to help Inuyasha defeat her. When Inuyasha returns to Yorei-Taisei's home with Kagome, he faces a male ox demon. Inuyasha uses his nose to locate Yorei-Taisei's demonic energy manifested around the demon in the form of vortexes. He is able to draw Tetsusaiga and cut the right vortex, clearing the hermit's test, but there is one final technique that Inuyasha has yet to discover.
