Shizuru at an agency hideout. After resting, the group faces off against Setsuna inside Tamamo-no-Mae's garden, with Kagura as the winner. However, Kensuke was gravely injured in the battle, leading Kagura to use the power of the sesshōseki to save his life. As a result, she loses control and becomes the core of the newly created Kyūbi, destroying the center of Tokyo. Kensuke manages to reach the Kyūbi, using his new Michael Revolution sword to free Kagura. Due to her brief time as the Kyūbi's core, Kagura has suffered amnesia, much to everyone's shock. She and Kensuke resume their daily lives at school, but start investigating ghosts alongside Kensuke, Tanaka, and Izumi, a new student who bears a resemblance to Yomi. Investigations lead the group closer to Naraku, the area in Tokyo destroyed by the Kyūbi and now filled with spirits. Kensuke later meets Mikado and Tsuina from the Agency. A few days later, Kensuke and Izumi are attacked by Kirin, a black wolflike monster from Naraku, who cuts Kensuke's right eye. Izumi is later revealed to be Yomi, who has dissociative identity disorder, alternating between Yomi and Izumi. When the revived Agency imprisons Izumi with the intention of exorcising Yomi, which will likely kill Izumi as well, Kagura breaks her free and the two go on the run. Kagura resolves to defend Yomi, disregarding others' opinions. Fending evil spirits and eventually the escorts of the Black Priestess—Yomi—they are cornered on a snow-covered cliff. There, Kensuke and Tsuina arrive to save them, leading to Kagura completely regaining her memories. The ensuing ruckus causes the cliff to collapse, causing them to fall near Micheal Kohara's residence, where Izuna and Shizune find them unconscious. After recovering, Kensuke and the others learn of Earth's impending destruction at the Black Priestess's (Yomi) hands and the White Priestess's (Kagura) potential to stop it. While everyone recuperates from resulting disbelief, government agents arrive to efface them: Izuna sacrifices himself for Yomi, relieving his guilt at allowing her previous deaths. She retreats with her retainers, mired in sorrow and her miasma, despite Kagura's pleas. After resurrecting Izuna with an escort's soul, Yomi arrives at Tokyo's Naraku, releasing all her miasma and disrupting the Reimyaku. Consequently, this gives rise to Immortals and Narakus worldwide. Kagura, Micheal, Kensuke, Tsuina and Shizuru search for Yomi. Following clashes with the Tengu, Okama and a revived Kyūbi, they encounter Yomi and Izuna,
