Episode 187

The episode begins with Kohaku jumping down toward a huge canyon which drives a furious Magatsuhi out of his body. At that point parts of Naraku's body appear from the sky and catch Kohaku from falling, attempting to take his Shikon Jewel shard. Sango cuts the tentacle with Hiraikotsu and frees her brother. Inuyasha uses Meido Zangetsuha to destroy Naraku but Kagome sensing the defiled Shikon Jewel tells Inuyasha that Naraku is still alive. Magatsuhi tells Inuyasha and the others that they have lost but Sesshomaru appears and draws out Bakusaiga as Naraku's tentacles attack him. Sesshomaru says to Magatsuhi that it ends here and that he had used Baykuya of Dreams to elude him and asks "are you that fearful of Tenseiga?" Kagome watches, knowing that only Sesshomaru's Tenseiga is capable of cutting Magatsuhi down and that when he is destroyed the full extent of her spiritual powers will finally be released. Magatushi tries to flee but Sesshomaru corners him, saying that he didn't destroy him right away because he wanted Magatsuhi to know who was killing him. He uses Tenseiga and Magatsuhi disappears in rage, saying that this is not the end, that he is indestructible. Kagome and Kohaku both wonder what he means, thinking that Magatsuhi is not entirely destroyed.

Meanwhile Miroku and Rin are still unconscious and are watched by Kaede and Jaken. An ominous presence leaves Miroku's body and envelops Rin. Sesshomaru rushes off to the village, and Inuyasha, Kagome, Sango and Kohaku intend to follow him. However Naraku appears and holds Kagome hostage, demanding that Kohaku give up his Shikon Jewel shard in exchange for Kagome's life. Inuyasha attempts to save her but is blocked by a barrier. Kagome knows that Naraku let his guard down because he believed that she had no spiritual power left, but unknown to Naraku Kagome still had the power and ability to locate the Shikon Jewel and finds it deep within his left shoulder. Kagome says this to Sango and Inuyasha ,and Naraku renders her unconscious. Inuyasha and Sango combine the barrier-breaking Red Tetsusaiga and Hiraikotsu to shatter Naraku's barrier and reach the jewel but both are shocked to find it protected by none other than Moryomaru's armored shell. Kohaku discovers that his shard is reacting to Kagome's glowing sacred arrow and allows himself to be captured in order to use the sacred arrow infused with Kikyo's purifying light to strike down Naraku, who is shocked to find that if he allows Kohaku to touch him any longer he will be destroyed by the purifying light and releases Kagome. Kohaku tells everyone that he always thought it would have better if he died back then but that the courage of both Inuyasha and Sango changed him and that he is ready to forget his sins and move one. But Naraku's tentacles pierce Kohaku's neck and take the final jewel shard, killing him. Elsewhere Naraku reassembles the Shikon Jewel and gloats over his victory and is ready to use the fully restored jewel to complete his transformation into a full-fledged demon.

A devastated Sango weeps over her brother's lifeless body. Enraged, Inuyasha demands that Kagome tell him where Naraku is. Kagome looks around and sees the fully restored fully defiled Shikon Jewel and fires her sacred arrow, knowing how powerless it is, and it shows Inuyasha who angrily draws out Tetsusaiga and uses Meido Zangestsuha but Naraku, laughing, escapes. He tells Inuyasha how weak he is: that he was unable to save Kohaku just as he was unable to save Kikyo. He also responds that Kikyo's light has also died out and escapes into the clouds.

As the sun rises Sango, Kagome and Inuyasha are soon surprised to see Kohaku enveloped in pure white light. Kagome realizes that Kikyo's light had left the Shikon Jewel and transfered to Kohaku, saving his life. With the Shikon Jewel finally complete the final battle between light and darkness, good and evil begins!
