A/N Part 1: Out of the vote Inuyasha won, and since in Japan Inuyasha anime series added a final act season that ended exactly at the end of the Inuyasha manga, I cross The Nine-Tail Fox's son with Inuyasha Anime series.
The Nine-Tail Fox's son ( s/4711667/1/The-Nine-Tail-Fox-s-son) was originally Naruto's POV, the first part is in Naruto's POV but the rest of the story will be 100% Normal POV.
Feudal Era's Nine-Tail Fox's Son
Prologue
(Naruto's POV)
Sasuke and I collided our final Rasengan and Chidori at each other.
A black sphere surround us and a portal opened.
I was pulled into it, but after Sasuke got away.
(Normal POV)
A girl with black long hair wearing white and red robes and a half dog demon wearing red robes were arguing over the half-demon telling her.
The girl was Kagome, and the half-demon was Inuyasha and the time was the feudal era.
Suddenly a portal opened in the air and Naruto fell through the portal into the river.
"Inuyasha save him," Kagome said.
"Why?" Inuyasha responded.
"If you don't I'll use those words," Kagome said.
"Okay I'm going," Inuyasha complained.
Inuyasha brought Naruto a shore.
"He's breathing," Kagome said, "I'm surprise he survive the fall."
"It might have to do with the fact he's full demon," Inuyasha said.
"Full demon, how can you tell?" Kagome asked.
"I can sense demon aura coming from him, and considering he has a smell of fox, he must be a fox demon" Inuyasha said, "Odd part is that this is the first demon I see that looks almost human."
"Maybe we should take him to Kaiede and decide what to do," Kagome said.
Half an hour later Naruto woke up and found himself in some hut, in some old ancient clothes.
Naruto saw his clothes drying on a bar.
"Where am I?" Naruto asked.
"You're in my village young fox demon," someone said.
Naruto turned to see Kaide coming in.
"Who are you?" Naruto asked.
"My name is Kaiede, and I'm curious about you," Kaide said, "Like who are you, what purpose are you here, and why you fell from a portal
"My name is Naruto Uzumaki, I don't know why I'm here or how that portal was created," Naruto said.
"What do you mean?" Kaiede asked.
Naruto explained about who he was, his heritage, living in a village, making human friends, becoming a ninja in the leaf village along with friends he made there, and how he led a retrieval mission to rescue Sasuke that led to so many battles including their battle.
"I see, something powerful must of send you here," Kaiede said.
"I guess," Naruto responded, "So where exactly am I?"
"The correct question will be when, as you're in feudal Japan," Kaiede said, "A time where demons and humans fought each other."
"Seriously?" Naruto responded.
"Yes, and from your story and from what I can tell, you don't mean any harm," Kaiede said and got up, "Your clothes should be dry by now, I'll let you dress. Then I'll introduced you to those who saved you."
"Uh, thanks," Naruto said.
"Also, word has already gone around about you being a fox-demon, so expect some coldness and hatred from the villagers," Kaiede explained, "We had problems with demons in the past, so it'll take time for them to accept you, but first I need to check on something."
"I'm use to it," Naruto said.
Kaide left and Naruto got dressed in his clothes vest and headband.
Naruto came out fully dressed.
"Ahh," Naruto shouted stretching out.
"So you are awake," a new voice said.
Naruto turned to Kagome standing there.
"Hello," Naruto responded, "My name is Naruto Uzumaki."
"Nice to meet you, my name is Kagome," Kagome said, "I was one of the two that saved you."
"Oh, thanks," Naruto said.
"So are you really a fox demon?" Kagome asked.
"Yep, well a 9-tail fox demon," Naruto said, "Where are you going?"
"Well I was hopping to use a well that got me here to go home," Kagome said.
"Home?" Naruto asked.
"Yeah well you see I'm not from this era, I'm actually from 1500 years from now," Kagome said.
"Seriously!" Naruto responded.
"Yeah, but I wanted to see if you were okay before I go," Kagome said.
"Thanks," Naruto responded, "Whose the 2nd person who save me?"
"A half dog demon name Inuyasha," Kagome said, "And a rude annoying one while at it."
"Inuyasha huh, I guess I should thank him two," Naruto said.
"Don't even bother, only reason he saved you was that I force him two," Kagome said.
"Oh," Naruto responded.
"Well I better get going, nice to meet you Naruto," Kagome said before leaving.
"Bye, good luck going home," Naruto responded.
Naruto decided to walk around getting to know the area.
He stopped seeing series of webs of hair around the area.
Naruto headed back to the village and saw that village women were being hold up by more hair.
"Something isn't right," Naruto said.
The women pull out weapons and came at Naruto.
Naruto made some handsigns and teleported from some attacks.
One hit Naruto and he turned into a log revealing to be a substitute.
Naruto was heading off finding Kaiede.
"Maybe that old woman can explain somethings to me," Naruto thought.
Just then Inuyasha tackled Naruto into the ground.
"I knew it you're the cause of it," Inuyasha said, "Where's Kaiede?"
"I didn't cause this, I'm looking for her," Naruto shouted.
"What?" Inuyasha responded.
"He's telling you the truth Inuyasha," someone shouted.
They turned to see Kaiede badly injured.
Inuyasha got off Naruto as they check on Kaiede.
The girls came at them.
"We need to stop them," Inuyasha said.
"Leave it to me," Naruto said.
Naruto took out a scroll and bit down on it with another scroll in his hands.
"Fox demon clone transformation Jutsu!" Naruto shouted.
Naruto summoned demon clones and transformed into his true form.
They tackled all the women and cut the hair without doing any damage.
Naruto transformed back to normal as his clones disappeared.
"Cleaver, I take it that was your true form," Kaiede said.
"Yeah, but I'm still growing stronger," Naruto said.
"Now we need to find Kagome," Kaiede said.
"She said she was going home," Inuyasha explained.
A demon called Yura controlling the hair saw this.
"So the blond hair one can see the hair as well," Yura said.
Hair surrounded Naruto and Inuyasha and tied them
"What the," Naruto said.
"Naruto Inuyasha find away out of there," Kaiede said, "Quickly!"
"Hold on I have something in my pouch," Naruto said.
Using one of his hands to somehow reach in his pouch and pull out a kunai.
Naruto summoned one of his tails and use it to grab the kunai and cut through the ropes.
Inuyasha tried to pull Yura out but she toss him back into the tree.
Naruto took out a shurikan and threw it.
Shurikan cut through the hair easily.
"That Fox-demon cut through all my hairs," Yuura said.
The village men got up and set to attack.
"You have any other attacks that can stop them Naruto?" Inuyasha asked.
"Not without hitting the villagers," Naruto said.
Kaiede passed out from bloodloss.
Naruto use bat transformation to fly around fallowing Inuyasha to safety as he carried Kaiede.
Inuyasha's body cut through the hair.
Yura was fallowing wanting Inuyasha's hair.
Once in safety it was sunset as Naruto treated Kaiede's wound.
"We must find Kagome," Kaiede said, "Her power might help."
"I can track her, but we got to deal with Yura," Naruto said.
"We have no choice," Kaiede said before passing out.
In Kagome's time, hours after Yura had somehow forced Kagome into the well, Kagome woke up in her time family well.
Kagome woke up in there remembering what happened.
Above Kagome's grandfather and her little brother Sota were trying something to get Kagome back.
They look down and saw that Kagome was back to their joy.
Kagome came out and to her joy found she was in her time.
Back in the feudal era, Naruto checked on Kaiede.
"She's still alive, but she's in no condition to fight. We need to hide her," Naruto said and turned to Inuyasha who was digging, "What are you doing?"
"I'm creating a hiding place, if we can cover some of her she'll be fine," Inuyasha said.
"Oh then I'll help," Naruto said.
As soon as they were done, they placed Kaiede into the hole and cover her up to her chest.
Kaiede woke up after they were done.
"What are you doing?" Kaiede asked.
"We're hiding you, you're in no condition to fight," Naruto said, "I'll dig you up once Yura is gone."
"Do you promise?" Kaiede asked.
"Yes, and I don't go back on my word," Naruto said.
"Alright, I trust you more than Inuyasha," Kaiede said.
"I can here you!" Inuyasha shouted.
"I'll make sure he doesn't kill any humans," Naruto said.
"I'm counting on you two," Kaiede said.
Naruto and Inuyasha headed off.
A/N Part Two: I thought of using episode 3 as the prologue since it's after the Sacred Jewel is already shattered into shards and spread out starting the hunt. The rest of Yuura arch will come in the next episode. Also there will be NO Next Times.
