Episodes 1 ~ 8
Episode 1: The Girl Who Went Back in Time, and the Boy That Was Sealed.
On Higurashi Kagome's fifteenth birthday, she fell through an ancient well and traveled back into to the Sengoku Jidai (warring times) of 500 hundreds years ago. There she was told by Kaede that she was the reincarnation of Kaede's older sister, Kikyo, a powerful priestess that guarded the Shikon no Tama (jewel of four souls) until 50 years earlier, when she died in a battle with Inuyasha, a half dog demon (inu-hanyou). Inuyasha was sealed by Kikyo's arrow on Goshinboku, a sacred thousand-year-old tree. And the jewel was burnt with Kikyo's remains. However, the Tama returned once more inside Kagome's body, and with it, a whole load of trouble.
In order to save herself and the village from a centipede, Kagome released Inuyasha from his seal, where the hanyou has been asleep for 50 years. After Inuyasha defeated the demon he turned on Kagome in demand for the jewel. The fact that Kagome looked just like Kikyo, his archenemy, did not help with his temper either. This hero wasn't as heroic as Kagome thought.
Episode 2: The One After the Shikon no Tama.
In order to stop Inuyasha from chopping Kagome to pieces, the old Kaede put a subdue spell over Inuyasha's neck in the form of a rosary. Whenever Kagome says "sit" or "osuwari" in Japanese, Inuyasha's head will hit the ground.
Kagome wondered off in search for a way back to her time, but instead was abducted by men who wanted the Tama. The leader of the men was a corpse in the control of a crow demon. Inuyasha came to Kagome's rescue but wasn't in time to save the jewel. In the fight with the demon, Kagome released an arrow which killed the demon, but also effectively shatter the Tama into a gazillion pieces. The pieces flew in different directions and Kagome was left with only one small shard.
Episode 3: I'm Back Through the Bone Eater's Well!
Even one small shard of the Tama could be dangerous. It's then been decided, at least by Kaede, that Kagome and Inuyasha should join hands, and search over the world for the pieces of the Shikon no Tama. Of course, Inuyasha didn't agree, especially when Kagome put on the miko kimono and looks incredibly like Kikyo. With only one shard with her, Kagome decides to go back to her world for the moment.
Meanwhile, the girls in the village are all controlled by a youkai named Yura of Hair. While the village girls hurt Kaede and distracted Inuyasha, Yura went after Kagome and took the shard she had. Yura pushed Kagome through the well and sent her back to her own time. Yura then focused on defeating Inuyasha, using razor sharp hair to strangle him, but it was not an easy task. The entire village is now under Yura's control. Yura saw Inuyasha's silvery hair, and decided to take his hair. Inuyasha wasn't able to see the hair, but Kaede was, and so would Kagome. Kaede told Inuyasha to go find Kagome.
Episode 4: The Hair Demon, Yura.
Kagome's grandfather sealed off the well with his "magical" seals, but Inuyasha was still successful in getting through. But as Inuyasha came to the modern world, Yura's hair followed him. Kagome was worried about her family's wellbeing, so she decided to go back with Inuyasha and destroy Yura once and for all. For her own safety, Inuyasha gave her his coat which was made out of fire rat's fur.
During the fight with Yura, Inuyasha was seriously injured since he gave Kagome his armor. And Yura seemed to be undefeatable He punched a hole through Yura's chest, but she still lived.
Kagome solved the mystery of Yura's immortality. Yura's real life source was actually inside a red skull. Kagome destroyed the skull with an arrow, and the comb that was hidden inside of it. Yura turned out to be a comb that was used to brush dead people's hair, and turned into a youkai because she was sick of it. After their victory, they retrieved the shard, and Inuyasha called Kagome by her name for the first time. It was their first victory together. Even if Inuyasha didn't want to believe it, he worried about Kagome, and cared about her a lot.
Episode 5: The Fearful Prince, Sesshomaru
In a search to find his father's grave and the ultimate treasure within it, Sesshomaru and his servant Jaken tracked down Inuyasha. A flea demon called Myouga, Inuyasha's father's old servant, warned Inuyasha of Sesshomaru's arrival. Sesshomaru turned out to be Inuyasha's half-brother. In order to lure out Inuyasha's hidden memories, Sesshomaru used Inuyasha's dead mother. And in an attempt to save Inuyasha, his mother brought him and Kagome to a different dimension. Only problem was, Kagome couldn't move or talk, Inuyasha couldn't see her, and the reflection of Inuyasha's mother in the pond doesn't have a face.
In this episode, Kagome finally learns what "hanyou" meant. Inuyasha's mother was a human, his father was a demon lord, and he, a mix of both blood, was shun by both races as a child.
Episode 6: An Omnious Demon Blade, Tessaiga
The woman wasn't Inuyasha's dead mother, she was Muuna, a youkai made out of the sorrow souls of mothers who lost their children to war and famine. Kagome finally escaped her chains with Myouga's help, and she helped Inuyasha to realize the truth just as Muuna was about to suck Inuyasha into her body entirely.
But it was still too late, Sesshomaru had enough information to find their father's grave, which was actually hidden inside Inuyasha's right eye. The group entered an entirely different world where Inuyasha and Sesshomaru's father's remains resided. They found the treasure, a batter old sword named Tessaiga that was increpted inside a stand. Neither Inuyasha nor Sesshomaru could pull it out. Inuyasha and Sesshomaru battled inside their father's stomach, and Sesshomaru was winning by far. In an accident, Kagome pulled out the sword easily, and this stunned everyone.
Episode 7: Clash! Sesshomaru vs. Tessaiga
Sesshomaru nearly killed Kagome, but Tessaiga's barrier protected her. To protect Kagome, Inuyasha fought full strength and he looked like he was winning. To defend himself, Sesshomaru revealed his real form as a giant white dog demon whose drool was poison (nice). But again, to protect Kagome, Inuyasha finally learned to transform the battered Tessaiga into a mighty sword, and with it, he cut off Sesshomaru's arm and they were able to return to the village safely.
Afterwards, Myouga said that because Inuyasha had compassion for humans, he was able to use the sword. And when Inuyasha said that he'll protect Kagome, the sword transformed. When Kagome asked if Inuyasha would always protect her, he started saying a bunch of crap she didn't like. So she pushed him onto a bridge and "sat" him. So in the end, Inuyasha still didn't figure out how to transform Tessaiga again. But their friendship was blossoming.
Episode 8: A Lord Youkai, Tsukumo no Gama
While Inuyasha, Myouga-jiji and Kagome travels in the Musashi area in search of Shikon shards, they stumbled into the young nobleman named Amari Nobunaga of the Takeda family (Kagome mistook him for Oda Nobunaga, an important figure in Japanese history) and his servant monkey Hiyoshimaru.
Nobunaga was in search of a princess that he used to served, whom was married off to a lord in the Musashi area. But the princess’ husband turned out to be possessed by a toad spirit, who fed on young women’s souls. Inuyasha suspected the involvement of a Shikon shard and they helped Nobunaga to rescue the princess. Inuyasha simply wanted to chop open the possessed lord’s body, but Nobunaga insisted that they free the lord from the toad’s grasp first. Kagome helped to defeat the youkai with a nice use of chemistry (hair spray with fire), and Inuyasha killed the toad spirit without any damage to the victim lord. Nobunaga couldn’t get the princess to love him in the end, but Inuyasha and Kagome gained another Shikon shard. And at the same time, Inuyasha learned the value of human life.
