Episode 172

The Great Holy Demon Spirit's Test is the 5th episode of InuYasha: The Final Act.

Summary
The Dragon-scaled Tessaiga has been giving Inuyasha trouble, so he goes to Totosai for advice (as usual). The only way to master the new form possessed by this blade is to train under the Holy Demon Spirit, the demon equivolent of a human hermit/sage.

In the meantime time, InuYasha isn't the only one looking to hone a new power; seems like Moryomaru's got his eyes on a power to strengthen his resistance to attacks and Sesshomaru is looking to master the circle form of his Meido Zangetsuha.

Plot
Kikyo is walking in a misty forest when Kohaku approuches her; she knows why he's come and the he's been following her since she absorbed Midoriko's soul. Kohaku wants Kikyo to use his shard against Naraku; he knows he will die. Kikyo is surprised by that Kokaku is welcoming of death; if they had met under different circumstances, Kikyo would have been able to mend Kohaku's wounded soul. Elsewhere, Inuyasha's group watches as Koga decides to Hakkaku and Ginta behind, despite their protests; they honestly believe he needs them. Koga explains that thanks to Naraku and Midoriko's will, he could end up putting them in danger; plus the wolf demon tribe has been put in danger of constant attacks from Naraku and Moryomaru, which is something he doesn't want. Inuyasha tells Koga not to beat him to the punch, while Koga tells him to master Tessaiga. Koga flirts with Kagome, barely missing a strike from Tessaiga; he leaves. Inuyasha's group bids farewell to Hakkuku anf Ginta, who walk off with Kai and Shinta.

Elsewhere, conjoined twin demons Ginka and Kinka fight in the sky above; Moryomaru watches from below. The Infant tells Moryomrau that Ginka and Kinka are forever bonded to eachother; if Moryomaru obtains this power, the bond between him and his armor will become stronger. Moryomrau flies off to eat the twins. In the meantime, Shippo and Kirara lead Totosai down from his volcano; he wonders what Inuyasha has done this time. Shippo tells Totosai that Tessaiga burnt Inuyasha. Totosai examines the blade, discovering it has taken Dakki's power. Inuyasha demands to know what's wrong, but Totosai tells him there is nothing wrong with it; if there's a problem, it lays with Inuyasha. Demonic is a type of poison; Tessaiga was originaly a fang from Inuyasha's father, who could absorb infinte amounts of energy. However, because Inuyasha is a hanyo, Tessaiga now has a limit to how much energy it can absorb. Totosai demands to see Inuyasha's hands, seeing burns; he can only think that Inuyasha is truly stubborn to endure this much pain. When Inuyasha tells Totosai that Tessaiga continued to get hotter, Totosai says Tessaiga was warning him. Inuyasha demands a solution for the problem with Tessaiga, so Totosai says to go see the Holy Demon Spirit, the equilovent of a wise old hermit; to master Tessaiga, Inuyasha needs to train under him.

Back to Moryomaru. He pierces Kinka and Ginka's body with Adamant spears; their blood falls on his armor. Moryomaru is surprised by how effective some of their blood, declaring he'll eat hem. They try attacking, only to miss. Moryomrau appears behind them and wraps them in his tentacles, but Ginka and Kinka use a combined attack on him; if this doesn't stop, Moryomaru will be destroyed. The Infant only laughs at the idea. Watching from near by, Byakuya of the Dreams observes, noting Naraku's heart will be in danger. He then manages to avoid a claw swipe from Sesshomaru, flying to safety on his origami crane. Byakuya says Sesshomaru should have at least introduced himself before trying to kill him, but Sesshomaru says that since Byakuya has Naraku's scent on him, it's all the reason he needs. Byakuya quickly deduces Sesshomaru's identity as Sesshomaru demands to know what Moryomaru is trying to accomplish; however, Byakuya says he's only an observer.

Moryomaru crashes to the ground, purposely losening his tentacles around Ginka, who sees Kinka is still fighting to get free; he fataly stabs him. Kinka calls Ginka a coward. Moryomaru pierces Ginka with his adamant spike, telling him they made all the more easier for him; Ginka had the opputunity to be free, but chose to kill Kinka. Moryomaru riddles Kinka with adamant spears and sucks both twins into his body. From the distance, Byakuya explains that Moryomaru was after the power binding Ginka and Kinka's demonic energy; Naraku is going to get more than he bargained for with this one. He turns to find Sesshomaru is gone, only for him to appear right behind Moryomaru. Sesshomaru offers to "help" test Moryomaru's new power. Moyromaru sends adamant spears coated with fire and lightning at Sesshomaru, who sucks them into a Meido. Moryomaru flees, having seen how deadly  Sesshomaru's new blade is. Before Sesshomaru can follow, Byakuya creates an illusion; Naraku wants Moryomaru to escape. Sesshomaru sends the origami cranes creating the illusion to the underworld, making Byakuya flee.

Elsewhere, Inuyasha's group is lead by Mo-mo to the village where the Holy Demon Spirit resides; it's very unlike a hermit. They come to a hut under a bridge, where they hear someone calling for help. They rush inside to find themselves in another dimension that appears to be a palce with mountains surrounding it. Miroku sees the dwelling fitting of a demon hermit. Kagome wonders where the cries for help are coming from as everyone sees what looks like a sheet hanging on a large flower; it's the hermit! Once rescued, the hermit explains he cannot train Inuyasha. Inuyasha begins wringing him, making Kagome give a Sit! command. The hermit explains that a demon attacked him the previous night and took his internal organs. Everyone offers to help, but the hermit insults them by saying only a full demon could help him. Inuyasha once more begns wringing the hermit. Kirara senses something.

Everyone goes outside, where they see demons inhabiting the village. Inuyasha goes to slay them but the hermit says to stop him. Kagome gives another Sit command. Inuyasha demands to know why he was stopped, making the hermit explain that they're not demons, but the human villagers. Demonic magic has made them change in appearance; the demonic energy that caused this is from his missing organs. Miroku is confused by this, but the hermit explains that while the demon is absorbing his powers, it cannot move, so it is most likely still in the village. As it requires less effort to blend in than to hide, the demon used the hermit's magic to transform all the humans into demon forms. Inuyasha says that all they have to do is find the real demon who stole the hermit's organs and get them back. The hermit agrees, but puts chains around Tessaiga; it's to prevent Inuyasha from attacking people at random.

inuyasha finds two real demons posing as humans in the crowd; they claim to be human, but Inuyasha points out that they can't fool his nose. When they attack him, Inuyasha tries drawing Tessaiga, but finds he cannot. Because of how weak the demons are, Inuyasha clobbers them instead. Angered, he demands the Holy Dishwag tell him why he couldn't draw Tessaiga. The Holy Demon Spirit explains it is because neither of them were the demon who stole his organs. Sango expresses how confusing the task is; Miroku concurs as unrelated demons are mixed in with the transformed humans. More chains wrap around Tessaiga, annoying Inuyasha; the Holy Demon Spirit explains it's punishment for assulating innocent demons. They are soon surround by angry villagers, who Inuyasha pummels to make a path to escape. The Holy Demon Spirit tells Inuyasha Tessaiga will disappear if he keeps causing more chains to appear.

A human boy named Genosuke leads the group inside his home to help them evade the villagers. The boy explains that he's scared; his mother has been bed-ridden since the previous night. He left to get medicine for her, but returned to find the village full of demonss. He takes them to the outside of his mother's room, where she's revealed to have been transformed into a serpernt demon. She realises her son is outside and calls to him. Inuyasha opens the doors, and the Holy Demon Spirit reveals that the aura coming from her is his powers. She transforms, losing her human face and becoming larger. She goads Inuyasha into cutting her belly open to take back the organs. Inuyasha tries drawing Tessaiga, but finds he cannot. The Holy Demon Spirit asks if Inuyasha needs or wants his sword. Miroku and Sango offer to assist, they're blow outside the house by a gust of wind. He lands a blow against the demon, but it heals; the Holy Demon Spirit tells him to look for the "demon vortex", causing the demon to send him, Shippo and Kirara away, just like Sango and Miroku.

Inuyasha continues to fail in wounding the serpent demon, wondering what the "dishwag" was trying to tell him about. The serpent demon wraps around Inuyasha, eninating a poiwerful venom to dissolve him. Kagome tries to help Inuyasha, but is held hostage by Genosuke, who has become a mantis demon. Inuyasha tries to get free, then finds he can see whirlpools of demonic energy, the demon vortex! Inuyasha discovers the true demon vortex, using Blades of Blood to free himself from the serpent demon. He claws through it, and the serpent demon is destroyed. Kagome, free of Genosuke, runs to Inuyasha, who reveals that an incense was hiding the demon vortex from him. However, Inuyasha then reveals that he can still sense the power of the stolen organs, meaning the true culrpit is still out there.

They run through the village, finding the spell is till in effect and Tessaiga is still wrapped in chains. Inuyasha catches the same smell and follows it to the Holy Demon Spirit's home, which has become dull and lifeless. There, they find the Holy Demon Spirit has been crumbled up and an ox demon claims to be the culprit, saying he has fully absorbed the organs of the Holy Demon Spirit. Inuyasha is angered by what's been done to the "dishrag" while the ox demon says he knows about how Tessaiga can absorb demonic energy; such a weapon needed to be prevented from being perfected. Inuyasha is angered by this, saying that if the ox demon is the one who took the organs, the seal the Holy Demon Spirit put on Tessaiga will break; he will avenge the "dishwag"'s death. Tessaiga pulses and the chains on it break apart; Inuyasha draws his blade and sees several demon vortexes. Inuyasha determines which is real and slices it with Tessaiga. However, this action causes a backlash and cracks Tessaiga. Inuyasha quickly realises the demon vortex he needs to cut is the Holy Demon Spirit's. He cuts it, and the ox demon vanishes.

Life returns to the Holy Dmeon Spirit's home. Miroku, Sango, Shippo and Kirara enter, bringing the good news that the spell on the humans in the village has been broken. The Holy Demon Spirit congradultes Inuyasha for finding the real demon vortex, taking a full-bodied form; he was thin a paper before. The Holy Demon Spirit claims this is his true form, but it's not really different. Miroku correctly guesses  the Holy Demon Spirit lied about losing his organs; he is, and the ox and snake demons were all part of an illusion the Holy Demon Spirit created to train Inuyasha. All the time Inuyasha was looking for his organs, he was constantly exposed to the Holy Demon Spirit's demonic energy, so he quickly learned how to spot demon vortexes. He put chains on Tessaiga to make it snap if drawn unneccasarily, explaining why Tessaiga zapped Inuyasha. The Holy Demon Spirit passes on a message for Totosai - "Tessaiga is not meant to absorb demon energy, but to cut it instead."

When asked why he cut the last demon vortex, Inuyasha explains it was because Tessaiga was cracked; he needed to end the battle quickly. The Holy Demon Spirit finds the theory is lost on Inuyasha. Inuyasha draws Tessaiga, seeing it is bathed in golden demonic energy. The Holy Demon Spirit explains his demon vortex has the power to rip other demon vortexes in half. Inuyasha flatly apologises for judging the Holy Demon Spirit by his appearance; Kagome says Inuyasha should be thanking the Holy Demon Spirit. The Holy Demon Spirit is surprised by Inuyasha's perosnality, but keeps secret that Tessaiga has a final form to be mastered.
