Naraku: Trap of Light is the 23rd episode of InuYasha: The Final Act.

Plot
As Magatsuhi fades from existence, Kagome feels a pulse as her complete spiritual powers return to her. Naraku begins shaking, causing her to fall. Inuyasha rushes to her, catching Kagome and getting bathed in a purifying light. Kagome notices that Inuyasha's demonic features have faded and he is back to normal. Inuyasha tells her it's thanks to her power of purification. However, Kagome says it's only thanks to Sesshomaru destroying Magatsuhi that she can purify him again. She goes to thank Sesshomaru for his help, but finds he's already gone. Elsewhere, Kohaku, Jaken and Shippo are seperated by Naraku, who is agrivated by the turn of events.

With the death of Magatsuhi a small dot of light returns to the Shikon Jewel thanks to Kagome's purification powers. Naraku knows that this ray of light will give hope to his foes; however, he decides to mold the ray of light into a ray of despair. Byakuya scatters several pieces of reflective papers throughout Naraku's body, spreading the light to ever corner. Naraku tells Inuyasha and Kagome about the light that has returned to the jewel, also informing them that Miroku has distanced himself from Sango to avoid drawling her into his Wind Tunnel, which is now dangerously at its limit, meaning he will be sucked in the next time he uses it.

At the same time, the light from the jewel reaches Miroku and Sango; Miroku prays his Wind Tunnel lasts until he can suck Naraku in, while Sango wants to find her beloved. At the same time, Inuyasha and Kagome race to find Miroku; Kagome notes that they're getting farther away from the real jewel, meaning Miroku will attempt killing Naraku in vain. Miroku reaches the source of the light, only to find a false Naraku, who congradulates him on being the first of his friends to reach him.

Meanwhile, Sango has encountered another false Naraku, however he holds captive the real Rin. Sango must choose whether or not to hurl her Hiraikotsu in hopes of killing Naraku to save Miroku, but at the cost of Rin's life. Kohaku reaches the area as well, but finds himself trapped behind a wall of flesh; he attempts to call to Sango, but Byakuya tells him that his efforts are in vain because his illusion of Naraku is all she notices. Sango decides that even if it means going to hell, she'll save Miroku. She tosses Hiraikotsu.

Just as this happens, Inuyasha and Kagome rescue Miroku before he can use his Wind Tunnel. Naraku taunts them, saying his illusions will not fade until they die. Kagome shoots an arrow, which disappears and reappears inside Naraku's barrier, severing his right arm. At that moment, Byakuya loses his right arm, losing focus on his illusion. Rin falls just in time to miss being hit by Sango's Hiraikotsu. Although Rin is freed and falls to her death, Kohaku manages to break out to save Rin before falling, Byakuya comments that Sango was willing to kill her, making sure Sesshōmaru overhears the conversation, seeing Rin lying in Kohaku's arms after being saved. He glowers but does not act. Sango begs him to wait to kill her until after Naraku has been defeated. Sesshōmaru seems fine with the delay.

Everyone heads off as Naraku's body falls apart around them, while Byakuya sneaks off to draw his sword, saying that it's time for him to draw it. Reaching Naraku's main body, Inuyasha attempts to kill Naraku with a strike from the Meidō Zangetsuha, but misses thanks to Naraku moving his flesh around. Shippō barely avoids the Meido as it glides past him; he watches as Byakuya absorbs the energy of the Meidō into his sword for a one-time-only use. Though he expects to be captured, Shippo is advised by Byakuya to leave Naraku before the wound closes up again. Byakuya of the Dreams then vanishes, angering Shippo.

Inuyasha, Kagome and Miroku notice Naraku has become serious about their deaths as his miasma has become more potent than it ever was; it's lethal to anything mortal, even to one with powerful purification powers like Kagome. However, this is noticed as Naraku becoming desperate. Inuyasha vows to kill his foe even though he's using Tessaiga for a barrier to keep Miroku and Kagome safe.
