Naraku attacks Kikyō, sending her into the miasma below Koga’s lack of appreciation sets off a new round of quarrels with Inuyasha. Inuyasha’s visions were a warning about the showdown taking place between Kikyō and Naraku. Reunited with Kagome, Kagome proudly tells Kōga that Inuyasha rescued him without her asking. Leaping to safety, Inuyasha has another vision of Kikyō. Meanwhile, Kagome waits for Inuyasha’s safe return and is relieved when she senses Kōga’s jewel shards on their way up. For once, Inuyasha agrees-neither does he! Slashing through the debris, Inuyasha sees the way out, but in the portal he sees a brief, disturbing vision of Kikyō. Kōga regains consciousness and complains he doesn’t want to die with Inuyasha. Hakurei, Inuyasha also searches for an opening, amid the hail of demon guts and rocks. The group reaches safety where they wait for signs of Inuyasha and Kōga. Higher in the cavern, all openings have vanished but Miroku creates an escape using his wind tunnel. He plucks Kōga from the deadly, reeking lake and sprints for an exit. Inuyasha struggles through a putrid rain of viscera and boulders toward the reservoir of toxins, finally locating Kōga. The evil swirl halts in front of Kikyō revealing Naraku. The malevolent maelstrom rolls down the slope towards her, cracking opening steaming fissures of miasma. Outside, Kikyō watches the mountain erupt, spewing a tornado of evil. Tearfully, Kagome implores Inuyasha to be careful as he vanishes into the darkness. Sensing her distress, Inuyasha entrusts Kagome’s safety to Shippō and follows Kōga alone. As the mountain collapses around them, Shippō begs Kagome to abandon Kōga, but she can’t. Inuyasha and Kagome chase the unconscious Kōga as he plunges towards Naraku’s caustic lake of miasma.
