Chapter One: To Drive Brothers Apart

It had been a terrible day for our heroes. They had randomly run into Sesshomaru, who was in a rather foul mood. So he took it out on poor Inuyasha. As of this exact moment 'poor Inuyasha' was sitting under a tree unconscious, badly beaten, and bleeding in many different places. Kagome and Shippo were patiently working on bandaging the badly abused hanyou.

"Myoga?" Sango questioned the flea who was currently sitting upon her shoulder, "Why do Sesshomaru and Inuyasha hate each other so much? I mean, they're brothers."

"Well it's a long story. But it all starts with a demon named Miori. She was Sesshomaru's favorite slave."

"A slave! I always knew he was a jerk!" Kagome pulled too tight on the bandage she was tying, causing Inuyasha to cry out in pain, "Oops. Sorry."

"He can't hear you." Myoga pointed out, "But continuing. Miori was half dog demon, like Lord Inuyasha and Sesshomaru, and half fox demon. Because she was not pure fox demon, her own grandfather sold her into slavery as a very young child. Miori believes he murdered her mother, but this had never been proven."

"Miori was a remarkably strong demon, both in strength and willpower. Along with this, she is a healer, making her invaluable as a slave. Because of her will, she ran away from any owner she was given to, and was often beaten as punishment. When she refused to bend to her master's will, she was resold. She knew over 50 different masters, all unusually cruel, within the ten years she was in slavery."

"Sesshomaru was a young child and Jaken was walking through the slave market running errands. He saw Miori on the auction, and seeing her dog demon blood, bought her on impulse. He brought her home, and presented her to Sesshomaru. She was a sort of companion to him as a child, and the two actually became very close rather quickly."

"As they grew up it remained the same way. They were the best of friends. Miori had a remarkable amount of influence over Sesshomaru. In fact, when Inuyasha's mother died, it was Miori who convinced Sesshomaru to take care of him. Miori raised Inuyasha as her own flesh and blood, and he looked upon her as an older sister. She was a bridge between the two brother's, as they fought constantly and didn't understand each other. Sesshomaru trusted her with everything. It was believed the two were in love with each other, but because of the fact she was a slave it was something they hid from everyone, including each other."

"It was roughly 75 years ago that the event that triggered the brother's feud happened. Sesshomaru was away, and Miori had been left alone with Inuyasha and the other slaves and soldiers at their home, when they had a visitor. Miori went to greet him, and it turned out to be her grandfather. He was infuriated when he saw she was alive, as he expected her to be killed long ago. He attacked her before she could do anything to retaliate, and she was badly injured. The commotion was noticed quickly, and her grandfather was thrown out. Sesshomaru returned to find Miori in a similar condition to Lord Inuyasha's at this moment. He blamed Inuyasha for not acting fast enough. Inuyasha blamed Sesshomaru for not being there. The two brothers fought bitterly over the matter."

"Miori recovered quickly enough, but the void between the brothers had deepened, and their vicious fighting persisted. Miori told me one day it broke her heart to see them fighting like that, especially as she felt it was her fault. It was several days after that when she simply disappeared. You see, Sesshomaru gave her an unusually large amount of freedom. She loved hot springs, and would visit them whenever possible. She had never been in one until she came to live with Sesshomaru, her former master's telling her she was unclean because of her mixed blood, and they didn't want her dirtying their water. She went out one night, apparently to visit the springs and never came back. The brother's blamed each other for this too, and their fighting continued to grow until it was the feud it is today."

At the end of the story the group just sat, staring at Myoga in disbelief.

"I can't believe that's true. They actually used to get along."

"Believe it all. It's true." Inuyasha's raspy voice broke through, "We looked everywhere for her, but we never found her. That's why Sesshomaru travels around so much today. He's still looking for her. He says he's not, but it's all a lie. He stops at every hot spring he finds, looking for some sign of her, but he's never had any luck."

A Month Later

It was a month later and the group had come upon a large valley. They had everything set up for the night.

"Hey." Inuyasha looked at the two girls, "I can hear water. It sounds as though there's a hot spring nearby. I know how much you two like to bathe." He snorted in slight distaste at this, but pointed in the direction of the spring nonetheless.

The girls gathered their things and traveled to the spring. However once they arrived, they found someone already occupying the springs. It was a demon with the same ppointed elfin ears as Sesshomaru, and silvery white hair that was currently pulled up messily to keep it from getting wet. It had moon pale skin and was humming beautifully to itself. It must have heard them because it turned around and it became obvious it was a female with the deepest blue eyes either of them had ever seen.

"Oh I'm sorry. I was just enjoying the waters. I'll leave you to your business now." The demon slid over to the edge and grabbed a silver robe edged in the same blue as her eyes, and pulled it on. It came halfway down her thighs, and was tied around the waist with a blue sash. As she tied her sash, Kagome and Sango saw her hands were clawed in a manner similar to Inuyasha's. She nodded to them once more, and slid away into the forest.

"Who was that?"

Review! If I don't get any reviews I'll just discontinue this, because I don't have the time/patience to write something no one will read. I'm sorry this was not well written. I decided to change the entire storyline after I wrote the whole first chapter. I also know this is not how the actual anime works, but I changed it for this story.
