In the face of a too-tempting reward, Miroku's eagerness to investigate the cursed castle of a giant oni, or "ogre," is at odds with the reluctance of Inu-Yasha. Is Naraku's absence from the scene a sign of increased demon activity to come? Next, in a more light-hearted vein, a misplaced monkey-god makes for mischief with Inu-Yasha and the others. Later, the reappearance of demon-slayer Sango's little brother, Kohaku, is just the start of new complications.

Inuyasha and his gang are up to their necks in enemies! First Miroko and Sango face off against a poison vapor-wielding adversary. Just when it looks like all is lost an unlikely savior shows up and single-handedly slays the sinister villain! From there things quickly get worse as Inuyasha is attacked by the half-man, half-machine, totally evil monstrosity known as Ginkotsu!

Inuyasha and friends encounter a strange mountain with mystical powers. The mountain is so sacred Kirara, Kikyo and Shippo can't even set foot on it! Meanwhile, the Army of Seven have resurrected their final member and now seek revenge on those responsible for their original deaths. Elsewhere Sesshomaru is in pursuit of Kohaku when he too is refuted by the purity of the mountain.

Inuyasha and comrades are deeply entrenched in the battle of their lives as they fend off the vicious attacks of the undead assassins known as the Band of Seven. But Inuyasha gains some unlikely allies when his brother Sesshomaru and feral rival Koga get entangled in the skirmish.

Trapped inside the holy shield of Mount Hakurei, Inuyasha's demonic power has been stripped away, leaving him vulnerable. Will Miroku's wind tunnel prove strong enough to break the barrier and free Inuyasha? And will Inuyasha's strength be enough to defeat the leader of the Band of Seven, who has absorbed the Shikon shards from his fallen comrades and become an even more formidable foe?

Inuyasha and the others are trapped inside Mount Hakurei with yet another newly reassembled Naraku. Meanwhile, Naraku reveals to Kikyo that his true purpose in hiding inside Mount Hakurei is to perfect an emotionless new form that could attack and even kill Kikyo without hesitation.

After a desperate battle against his own half-brother, Sesshomaru, Inu-Yasha now holds his demon-father's great sword: the Tetsusaiga, or "Steel-Cleaving Fang." But the Tetsusaiga has an odd quirk for a demonic weapon - it can only be wielded in defense of humanity!

Evil Kagura and demonic baby Hakudoshi are searching for the border between the afterworld and this world, where it is said that the last Shikon Jewel shards lies. Inuyasha and the others are also doing everything they can to recover this last shard. Could it be that Inuyasha and Kagome have been to this border before?!

The search for the final shard of the Shikon Jewel leads Inuyasha and the gang to a mountain fortress. But the gate is guarded by two giant statues and a force that will only allow the dead to enter! Seeking a path to the underworld, Naraku meanwhile teams up with a new demon, Abi Hime, who hunts the blood of innocent villagers to heal her mother. Inuyasha and friends step in to stop them when they find that Kikyo may be involved!

Kagome faces a difficult decision - only she can help Kikyo heal from Naraku's miasma. Will the love triangle between Kagome, Inuyasha, and Kikyo stop her from doing the right thing? Kohaku comes under Naraku's power and is ordered to steal the infant Hakudoshi. Will Kohaku be able to resist? While Inuyasha and his comrades watch, Naraku shows up at the demon bird's nest for a showdown!

A fierce battle rages in the borderland lying between the world of the living and the afterlife. A mysterious force is attacking Inuyasha and preventing him from obtaining the last Shikon shard. This force claims to be acting on behalf of the will of the shard! Inuyasha also faces the dreaded Naraku, who will stop at nothing to obtain the shard. When all hope seems lost, Inuyasha receives help from a surprising force: his half-brother!

Inuyasha and the gang follow a trail of rumors that lead to a "living mountain." Naraku has awoken the mountain from its 200-year slumber and stolen its sacred stone. The "living mountain" then gives a gift to Inuyasha and his group to help them in retrieving the stone. But what could Naraku be hoping to achieve?
