Inuyasha: The Final Act

Using the fragment of Kanna's mirror given to him by Byakuya, Sesshomaru is able to make Tenseiga replicate Tetsusaiga's powers and abilities and challenges Inuyasha to a battle to test his worthiness to wield their father's fang of destruction. Every time the swords cross, Tetsusaiga regains some of its powers and abilities back. Sesshomaru uses Meido Zangetsuha on Inuyasha and throws Tenseiga inside, but Inuyasha cut through his demonic enegy to save himself. Naraku tries to control Tenseiga through Kanna's mirror, but Sesshomaru jumps inside Meido Zangetsuha and forces Inuyasha to break Tenseiga. Tetsusaiga's blade becomes black, Inuyasha uses Meido Zangetsuha to exit the Underworld and the broken Tenseiga comes back anew. Now freed from his obsession with Tetsusaiga, Sesshomaru is one step away from obtaining a much more powerful weapon of his own that is not inherited from his father.

Naraku attacks and fatally wounds Hitomiko, a priestess with unusually strong and powerful spiritual powers and abilities that he previously tried to kill fifteen years ago. Using the Shikon Jewel, he keeps her alive and uses his spiderwebs to control and manipulate her. He has her erect an incredibly strong and powerful barrier that traps Kagome, and begins torturing her to death. Kagome shoots the spider controlling Hitomiko, though she worries this will corrupt both Hitomiko's soul and spiritual powers. When she fires her sacred arrow, a huge light purple glowing ray of intense spiritual power shoots out and Hitomiko is able to die peacefully in Kagome's arms, after first telling Kagome that she can sense that Kagome's true spiritual powers are highly extensive, but are somehow sealed.

Inuyasha returns to Kaede's village to tell her of Kikyo's death. Kaede states that Kagome's innate spiritual power was probably sealed by Magatsuhi, the evil will of the Shikon Jewel who did so out of fear. Meanwhile, as a countermeasure against Kikyo's spiritual powers, Naraku provides some of his flesh to give Magatsuhi a physical form, ordering him to retrieve Kohaku's jewel shard. Sesshomaru struggles to defend the boy without a weapon or a left arm. Inuyasha's group arrives to find Sesshomaru's right arm badly wounded and Kohaku's shard being defiled. After Magatsuhi renders Kagome unconscious, Sesshomaru heals his wounds and assumes his true form to attack, but to no effect. The brothers struggle to battle Magatsuhi, while protecting their respective groups. Sesshomaru ends up speared and trapped in a ball of appendages, yet is able to burst through. When Totosai then appears, Sesshomaru's left arm is restored and he is wielding a new sword named Bakusaiga, able to rot whatever he cuts, forcing Magatsuhi to flee after destroying the evil spirit's vessel. Soon after, Kagome finally awakens with a puzzled expression on her face.

Inuyasha and Sesshomaru's groups go to Kaede's village, where Kohaku remains unconscious due to the defilement of his jewel shard, but not even Kagome can purify it, seemingly due to Magatsuhi's mental attack against her. After Totosai makes a scabbard for Bakusaiga, Sesshomaru leaves Jaken and Rin with Kohaku to hunt down Magatsuhi. Kagome decides to return home to take her high school entrance exams, promising to return when they are done. However, Kagome is at a loss since her family is away on a trip, the school is closed and her friends are unavailable. Inuyasha visits her, advising her to stay at home until Naraku is defeated, and he believes her spiritual powers and abilities were sealed by Kikyo's final wish not to fight anymore. Kagome wants to keep her promise to Kikyo instead and to make the one correct wish that will make the sacred Shikon Jewel disappear from world of the living forever. Inuyasha vows to protect Kagome with his life, and they almost kiss passionately, but are interrupted by the sudden return of her family. Ten days later, Kagome goes on her way by train to take her entrance exams, but is persistently followed by Inuyasha. Kagome's bag gets caught in the train when exiting, but Inuyasha carries her after the train to retrieve her bag. Inuyasha takes her to the exam site, where her mother meets her with the exam ticket she somehow left at home.

Kohaku successfully drives Magatsuhi out of his body, just as Sesshomaru arrives, using Bakusaiga by destroying Naraku's appendages and then using Tenseiga by cutting Magatsuhi in half, yet still able to escape. When Sesshomaru heads back to the village, Naraku manages to capture Kagome and demands Inuyasha's group gives him Kohaku's jewel shard in exchange for her. Discreetly spotting a sacred arrow on the ground before offering himself to Naraku, Kohaku stabs him in the right shoulder, shattering the turtle shelled armor previously absorb by Moryomaru, prompting Naraku to retreat. Meanwhile, as the Wind Tunnel is close to consuming Miroku, a fragment of Magatsuhi possesses Rin's body to fly off with a demon. After Kokaru reunites with the others, a piece of Naraku's flesh pierces Kohaku's neck and takes the jewel shard, leaving his empty body behind. Luckily, Kohaku is brought back to life by Kikyo's light after her spirit hears Sango crying for him. With the Shikon Jewel now complete in Naraku's hand, the final battle between light and darkness begins.

Kagome happily learns that she has been put on the waiting list for high school, finally graduating from middle school with her friends. Hojo wishes to give Kagome his second button, a tradition in Japan which means that the boy likes the girl, but she leaves before he can. Meanwhile, Naraku has absorbed the power of the Shikon Jewel and a dark cloud spreads over the land. Inuyasha's group leaves to defeat Naraku, leaving Shippo behind in the care of Kaede. As they find Naraku and Byakuya in a cloud of miasma, they see Sesshomaru enter Naraku's body in search of Rin. As Inuyasha's group enters, Miroku pauses to propose to Sango. They soon realize that though they are breathing in the miasma, it is not harming them because the Shikon Jewel wants to capture their souls first. Inuyasha and Kagome search for the defiled jewel, after Miroku and Sango are captured. As Inuyasha gets closer to the Shikon Jewel, he turns into a full-blooded demon and attacks Kagome. Naraku offers Kagome a miasma-coated arrow to save herself with, but she refuses. Naraku says Inuyasha will kill her, just as he had killed Kikyo. Inuyasha attacks again, throwing her off a cliff.

Miroku and Sango are shown an illusion of Miroku's father being sucked in by his own Wind Tunnel. Inuyasha momentarily regains his humanity when he hears Kagome's voice, but diverts back to his demon form when his heart is devoured by the Shikon Jewel’s poison. After Miroku uses his Wind Tunnel to save Sango from oncoming demons, Miroku recommends that he should part ways with Sango. Rin, finally gaining her consciousness, is chased by Magatsuhi. She encounters Inuyasha, who ends up being possessed by Magatsuhi after a failed attempt of attack. When Sesshomaru and Kagome arrive, the former takes on the possessed Inuyasha, while the latter attempts to retrieve Tetsusaiga, which Magatsuhi tossed aside due to its connection to Inuyasha's senses. As Kagome pulls the sword, she falls over the cliff, but is able to hold onto the side. Inuyasha regains control of his body after hearing Kagome's voice and when Tetsusaiga is returned to him. Magatsuhi tries to possess Kagome, but Inuyasha uses Tetsusaiga to draw out the demonic energy and Sesshomaru uses Tenseiga to dispel the evil spirit once and for all.

After Magatsuhi's defeat, Kagome's innate spiritual powers and abilities are released to their fullest extent with Shikon Jewel having a spark of pure light within it. Naraku tries to eradicate the pure light by sending out illusions, one to trick Miroku to using his Wind Tunnel for one last time, and another to make Sango kill Rin to save Miroku from the Wind Tunnel. Inuyasha makes it in time to prevent Miroku from opening the Wind Tunnel. Kagome's sacred arrow hits Naraku, destroying the illusions and freeing Rin with the Hiraikotsu. Though Rin is freed and nearly falls to her death, Kohaku comes to save her before hitting the ground just in time. Inuyasha, Kagome and Miroku see Naraku's true body as his miasma starts to fill the air. As Inuyasha sends a Meido Zangetsuha traveling past Naraku, Shippo later sees Byakuya intercepting it with a strange blade to rob some of this dark orb's energy. Sango protects an awakened Rin from the miasma by giving the girl her protective mask.

Naraku releases more miasma, while Inuyasha uses Tetsusaiga's barrier to protect himself, Kagome and Miroku. Sango arrives riding Kirara and throws her Hirakotsu, but it absorbs too much of the miasma and Sango falls through a hole that Naraku opens in his flesh. Miroku follows and she decides to die with him there. When Kagome questions Naraku about whether his real wish has come true, he becomes enraged. As he absorbs the Shikon Jewel, he begins transforming and spreading spiderwebs around the area. Inuyasha unleashes Meido Zangestuha, which takes on the form of slashing blades due to the different nature of his sword. Miroku and Sango fall again, but are joined by Shippo. Byakuya slashes Kagome across the back with his blade, but strangely it leaves no wound. Inuyasha quickly attacks and kills Byakuya, who states that he has fulfilled his purpose. Together, Miroku, Sango, Shippo and Kirara, along with Sesshomaru's group, join Inuyasha and Kagome in the final battle against Naraku.

Naraku transforms after finally feeding his soul to the Shikon Jewel, vastly spreading miasma in the area. As the group exits the large mass of misama, they find themselves over the Bone Eater's Well near Kaede's village. After Naraku's body is destroyed by Inuyasha's Meido Zangetsuha, Kagome pierces the Shikon Jewel with an unusually powerful sacred arrow, dealing him a fatal blow. It is learned that Naruka's true wish was Kikyo's heart, a wish that the Shikon Jewel never granted. Miroku's Wind Tunnel vanishes after Naraku's soul has been purified, but a Meido opens behind Kagome and pulls her in along with the well. Kagome finds herself in front of her high school, resuming her normal life with her friends and family, but without any memories of Inuyasha or the others. However, she is bothered by a nagging sense that something is wrong. When she touches the Sacred Tree, her memories return and the spell is broken, but she is then surrounded by darkness. The voice of the Shikon Jewel tells her that she will forever remain there, lest she makes a selfish wish to return to her own time. Meanwhile, Inuyasha uses Meido Zangestuha to jump into the darkness after Kagome. As Inuyasha battles through the demons, he yells to Kagome not to make any wishes yet, since doing so would bound her inside the Shikon Jewel, battling demons for an eternity.

Inuyasha's voice is ultimately able to reach Kagome, who remembers her grandfather telling her that the one and only correct wish will cause the Shikon Jewel to be banished from the world forever. Inuyasha battles his way to her and after they share a loving kiss, she makes the one and only correct wish, shattering the Shikon Jewel from existence. Three years later, eighteen-year-old Kagome, who is now graduating high school, recalls how Inuyasha and her returned to the present. The well then transported Inuyasha back to his time and stopped working since then. In the present day, Kagome returns to the well and realizes her own feelings were what was blocking the well. When she wishes to see him again, the well reactivates and she bids farewell to her mother and enters the well. Inuyasha quickly catches her scent, meets her, takes her by the hand, and embraces her. Kagome's family and friends continue to live as they always have. Kagome's brother Sota Higurashi tells his friends that his sister got married right after high school and moved away; Kagome's friends are in college; and Hojo is dating an underclasswoman. Shippo is training to become a strong fox demon; Sango and Miroku live with their three kids in Kaede's village; Kohaku is off to train to become a strong demon slayer; Myoga continues to live with Totosai; Koga gets married to the wolf demon girl Ayame; and Rin lives with Kaede in the village where Sesshoumaru and Jaken are shown paying her visits. Inuyasha said that this was practice for returning her to a human village or whatever she chooses. Kagome is contently adapting to her new life in the feudal world as Inuyasha's wife.
