Noticed a few mistakes i made so i went back in fixed them, other than that i didnt change much with the actual story line, oh apart from a little bit at the real end with inu, so just read that last bit again before moving on.
It first started on a Sunday afternoon; Sesshomaru had been cursing himself for not being able to wield tetsusaiga when he was approached by a strange being, they didn't smell human, nor demon but the same as Kikyo.
'The un-dead' he decided
Sesshomaru hated the un-dead, he thought people that died should have the decency to stay dead and leave him alone but lately there have been a number of un-dead bothering him.
"Tell me soul, what is it that has you so annoyed?" she asked
"Leave me, return back to your grave"
"Still haven't got the tetsusaiga I see"
Sesshomaru shot a death glare at the un-dead girl.
"I'm already dead; your glares can't harm me"
"I can destroy your body"
"That's true, but let's not resort to that. I will leave you if you would grant me that answer to a single question"
He didn't reply so the girl took this as approval to continue on.
"Would you do anything to get your hands on tetsusaiga?"
"Of course" he grumbled
A wicked smile appeared on her face as she pulled out a container from her sleeve.
"Drink this, drink this and tetsusaiga will be yours"
Sesshomaru took a few seconds to think this through, it could easily be a trap but he thought he would be able to overcome any trap that this dead girl could present. He took the bottle from her hands and drank it, it didn't have a taste, it felt like all he was drinking was air but still he continued to drink until the container was no longer full.
"Now what?"
"Goodnight" she smirked
His head started to spin and even though Sesshomaru resisted as much as he could he still feel to the ground in a deep sleep.
When he woke up next something didn't feel right. He went to stand up only to find he was now in a tree, as he tried to steady himself he realised his reflexes weren't as good as normal. Just managing to land semi-graceful he noticed this isn't where he should be and he could smell his brother all around him, he also noticed the sleeping figures near him, it was those of Inuyasha's group.
"What am I doing here?"
"Inuyasha is everything ok?" Kagome asked with a yawn
She sat up and looked over towards Sesshomaru and started at him.
"Hello I'm talking to you" she huffed
"Inuyasha fell out of the tree" Shippo smirked
"Oh no, did you have a bad dream?"
"Why is the priestess talking to me like that?"
"Why are you so quiet Inuyasha? Oh I know what will make you feel better, how about I cook you up some ramen?"
Even though Sesshomaru would never be caught dead eating human food he felt a part of him get excited at the word ramen.
"What is going on here, and why does she keep addressing me as that half breed"
He watched as Kagome fished around her bag and the others waking up, they all talked mindlessly and didn't pay any attention to him.
"What's wrong with Inuyasha? He is quiet this morning" Miroku asked Kagome
"I don't know... he fell out of the tree this morning and he hasn't said a single word... maybe he hit his head?"
"With a thick head like his it would be hard to do any damage to it" Shippo giggled
Deciding to use this to his advantage Sesshomaru just sat quietly listening in on the others. While he was listening to them he found that his other senses weren't as good either, he couldn't hear things from very far, he couldn't sense things as good and his nose also didn't smell things as great as normal but the one thing that he noticed the most was his lack of power.
"What is wrong with me?" he wondered looking around him "if Inuyasha has anything to do with this I will kill him"
"It's ready, here you go Inuyasha"
Kagome was right in front of Sesshomaru now holding out the ramen cup, despite Sesshomaru's better judgment he still reached out and grabbed it only to notice he was reaching out with his left hand and there was red clothing covering his arm. He pulled both his hands in front of himself and noticed they weren't his hands. As fast as he could go, which was slower then he was used to, he searched for water with a feeling of fear he had never felt before.
Kagome placed the ramen cup on the ground and went running after Inuyasha leaving the others alone, she found him standing near a river staring down into the water.
"Inuyasha are you ok?"
He turned around to face her, his ears were flat and his face was a deathly pale.
"Inuyasha?" Kagome reached out her hand carefully towards him "Inuyasha what's wrong?"
"What happened to me?" Sesshomaru asked despite himself
"What do you mean?" Kagome asked clueless
"My voice even sounds like that no good half breed"
"Inuyasha?"
"Stop addressing me as that worthless half breed" he growled
"What do you mean?"
"Humph, I expected as much from a useless human, you haven't even noticed something is wrong with your mate"
"Ma... mate? Inuyasha IS NOT MY MATE!" she shouted "wait... worthless half breed... useless human... mate... SESSHOMARU!"
"That is Lord Sesshomaru to you"
Kagome started to walk backwards with one hand over her heart and the other one covering her mouth; she couldn't believe what she was hearing.
"How did Sesshomaru become Inuyasha... where is the real Inuyasha?"
She wasn't looking where she was going and tripped on a tree root. She fell down but didn't bother to pick herself up, all Kagome was capable of was staring at Sesshomaru with fright and worry.
"But how?" Kagome managed to ask
"I don't..."
Sesshomaru stopped; he refused to say those words.
"You" Kagome hissed through her teeth staring at the ground
Sesshomaru raised his brow but it didn't feel right, Inuyasha's face just wasn't the same as his own.
"You did this!" she shouted glaring up at him
Sesshomaru felt Inuyasha's ears twitch and cursed the body he was in.
"Why would I purposely switch bodies with this weak half breed?" he scoffed
"You tell me"
Sesshomaru didn't look like he was going to answer her anytime soon so she decided to try something, he was in Inuyasha's body after all and the rosary beads were around his neck.
"Sit!" she shouted out
Sesshomaru found himself being slammed into the ground at full force, he tried to pull himself up but it was like he was being dragged down.
"What is this?" he hissed
"Where is Inuyasha?" Kagome demanded standing over him
"How could I possibly know that" he growled
"Sit!" she shouted once again "where is he!"
This went on for a while until Inuyasha's body was aching all over and Kagome's voice was beginning to get sore, she stopped yelling at him and went over to the stream for a drink.
"I guess he really has no idea..." she thought with a sigh looking back at Inuyasha's body still lying on the floor "what do I do now then? I have to find Inuyasha"
"I will kill you for this wench"
"Try and I will s i t you" she threatened
Whether he like it or not Sesshomaru was stuck in this body and forced to put up with these people.
"What is the last thing you remember before?"
"Some dead girl bothering me"
"Kikyo?"
"No but like the miko"
"And what did she want"
"She said she could give me tetsusaiga"
That's when Sesshomaru understood what happened, that un-dead girl had somehow placed him in the one body that can control the tetsusaiga.
"The tetsusaiga is useless in this body" he scoffed
"If you're in Inuyasha's body... does that mean he would be in... yours?" Kagome asked thinking out loud
Fear appeared on Inuyasha's face which only served to make Sesshomaru angrier, he hated how easy Inuyasha's feelings where to read.
Inuyasha woke up feeling different, he felt better than he ever had, he felt more powerful than even his demon form and his senses were better to and the first thing he smelt was his brothers scent alarming him.
"Good morning Lord Sesshomaru"
Inuyasha jumped up but his body moved much faster than he was used to nearly causing him to fall back down. He saw a young girl standing near him looking up with a smile.
"Did you sleep well?"
"What did you call me before?"
As his words came out they had a certain coldness to them and his face felt stiff.
"Lord Sesshomaru" she smiled happily
Inuyasha tried to widen his eyes but they just didn't seem to widen the same way he was used to, he smelt a spring nearby and made his way to it. He reached it within seconds even though it was fairly far away, he stood over the water looking down at his reflection then went to draw his sword only to find tokijin and tenseiga in its place.
Inuyasha shouted out in fear, he had become his brother; surely this was just some nightmare. He tried everything to wake up before accepting that he wasn't sleeping.
"I'll find that bastard and kill him" he growled with a cold glare storming back to Rin and Jaken
"Master Jaken... is Lord Sesshomaru ok?"
"Stop calling me that" he hissed
"Dammit I can't stand this, I sound just like him... even my thoughts sound like him!"
He stormed off in a direction not really too sure where he was going but Inuyasha had a feeling he was going in the right direction.
"Lord Sesshomaru wait for me!" Jaken screeched
Inuyasha stopped and looked back at the annoying toad and the human girl, they often followed Sesshomaru and from what he saw he was their protector like he was over Kagome and the others so Inuyasha didn't have much choice but to slow down and allow them to follow him. He couldn't understand how Sesshomaru had the patience to walk so slowly when he could be anywhere in half the time if he wanted to.
During the course of the day he would hear Rin and Jaken fighting and wondered even more how he put up with it but one good thing was they left him out of it, in fact despite the noise he was rather lonely. Inuyasha was used to Kagome talking to him or Kagome including him in the others conversation; she was the one that kept them all together.
After a while he heard Rin starting to slow down and despite himself not being tired or even the slightest bit hungry he guessed she might be. He stopped then turned and faced them looking down at them which only seemed to make them look a little worried.
"Do you want to stop?" he asked bearing the sound of his voice
They looked at each other a little confused and even more worried than before.
"What?" he snapped at them
"Lord Sesshomaru... it's not my place to question... but are you feeling alright?" Jaken mumbled
"Of course! Now do you want to stop or not?"
They shook their heads, he knew they were both tired but if they didn't want to stop then Inuyasha was more than happy to move on.
"When you want to stop, tell me" he told them before continuing on
They didn't end up stopping until that night when Rin finally spoke up, Inuyasha found a safe place for them and while Rin made a fire he went to look for food for them.
"Don't move until I get back" he warned them
Inuyasha left them then using his brother's full speed make it to a lake and back within minutes carrying enough fish for them all. They looked surprised as Inuyasha placed the fish down after all it was one of the first things Sesshomaru had told Rin, she would have to find her own food and now he had done it for her.
As the fish cooked Inuyasha didn't feel the slightest bit hungry, it was true that half the time he ate with the others it wasn't because he was hungry he just really enjoyed the food but now he didn't have the slightest interest in eating it at all. Rin and Jaken were used to Sesshomaru not eating so when Inuyasha just sat there not bothering to get any food they didn't think anything of it, while they were eating Inuyasha started to think of something to say to them. With Kagome and the others there was always a joyful talk around the fire and he had grown used to it but here there was nothing but silence.
After a while Rin started to hum a song that sounded familiar to Inuyasha, it was soothing and nice but then she was interrupted by Jaken.
"Stop that silly noise!"
"It's not silly noise it's a song"
"It's nothing but racket!"
"Jaken" he said in a growl
For a reason Inuyasha didn't know whenever he said Jaken's name in that tone he stopped whatever he was doing.
"Lord Sesshomaru do you like my song?"
"There aren't any words"
"... I don't remember them... I only heard it once when I was with Lady Kagome and the others"
"That's where I know it; it's that silly song she sings to Shippo"
"Today is ending and silently the morning begins, your tired body relaxes and slowly eases to sleep" he said closing his eyes
Rin's eyes widened as she heard the lyrics, she had hummed the song many times before but never once had Sesshomaru said anything about it and now he was telling her the lyrics.
"What next Lord Sesshomaru?"
"From the first time I met you, the profile that you show to me always has its eyes fixed on the morning with eyes full of determination. You do not need to hurry there is no reason to beat anyone, surely there is somebody who loves you"
Rin had moved closer to Sesshomaru sitting on her knees listening eagerly for every word but she frowned a little once he stopped.
"I don't remember the rest" he told her
"Can you teach me?" she asked with pleading eyes
Inuyasha sighed and opened his eyes looking at the girl "maybe tomorrow, for now you need to sleep"
Rin obeyed him without question tell him goodnight before curling up on the ground and falling into a peaceful sleep. As she slept Inuyasha couldn't help but wonder why Sesshomaru would keep her around, she slowed him down, talked lots, couldn't defend herself but yet as he sat there he felt the need to protect her from any harm.
He looked up at the moonless sky with worry, right now Sesshomaru would be in his body and human.
"At least he can't hurt them as a human" he thought with a small smirk "But still... I wonder if the others are fine without me"
