Episode 137

An Ancestor Named Kagome is the 137th episode of the InuYasha anime.

Plot
Kagome is taking a history test in school. She is frustrated that she didn't do well. As she, Yuka, Eri, and Ayumi are talking, Hojo enters with his family tree. He shows them that the wife of his ancestor, Akitoki Hojo, was named Kagome.

Kagome's friends gossip about Hojo's family tree. They show Kagome photos from the Cultural Festival.

In the Feudal era, bandits threaten Akitoki. Inuyasha and Shippō come to his rescue. Akitoki is seeking Kaede for information about the Naginata of Kenkon. When he unwraps the Ken blade, Inuyasha becomes entranced by the blade's demonic aura.

Akitoki was heading for Mount Hakurei to purify the blade, but the mountain is gone. He seeks Kaede for another place to purify the blade. She sends Akitoki to the Shrine of Furai near the Shoun Waterfall, the holiest place she knows of.

Akitoki begs Inuyasha, Shippō, Miroku and Sango for help, and is thrilled to find out that Kagome will be joining them.

Kagome arrives in the past, and they all depart for the Shoun Waterfall and Furai Shrine. Along the way, they are attacked, but they repel the assassins. Myōga joins them after Akitoki has told what he knows of the Ken blade and Kon blade. Myoga has information from Tōtōsai about the Naginata or Kenkon. They also learn of Hoshiyomi, leader of the demon ninjas, who is seeking to recreate the Naginata of Kenkon, which he had forged in the first place.

A night time ambush separates the group when Kagome and Akitoki fall into a river.

Trivia

 * InuYasha and the others rationalise Kagome's bag is full of ninja tricks when she gives Akitoki a hot-cool press when bad luck causes his tea cup to break and burn his hand.

Errors

 * This is the first time Akitoki is seen in the series yet the way they talk they act as if they've known him for awhile now. For example, when Inuyasha saves him from being robbed by bandits he says "What, got yourself into trouble again?" and he's speaking to Akitoki which implies that he's gotten him out of trouble before. Then another example, Shippo says "Hey your looking good Akitoki" and he also says "Akitoki is still my vassel, and it's a masters responsibility to come to the rescue of his servants." This again implies that he's known Akitoki before this episode. This is a huge error in the series. Yes he is introduced in the movie before this episode but if somebody hasn't watched the movies this could be extremely confusing for them.
