Set 19 Years before the pilot
They awoke in an opening in the forest in wonder of what place they were in. A woman with red hair and a curvy figure, a man with white hair, claws, and dog ears, and a man with black hair, a mysterious demeanor, and red piercing eyes.
Erza- Who are you two and what are your intentions?
Inuyasha- I'm Inuyasha and I have no intentions with either one of you I just woke up in this damn place.
Itachi- I'm Itachi Uchiha and you are my lady?
Erza- I'm Erza Scarlett and I recently died in battle with a man named Zeref.
Itachi- I recently died in a battle again with a craze Shinobi.
Inuyasha- Same here died killing a demon named Orgath and saving my great great grandchildren.
Itachi- Wait did you say great great grandchildren?
Inuyasha- Yes I did. Did you say you died again?
Itachi- That's correct.
Inuyasha- Seems like you had an odd life.
Itachi- It was interesting to say the least. If you don't mind my asking why are you ears shaped that way?
Inuyasha- I'm half Yokai half human. Yokai are creatures of great and various power, they come in all shapes and sizes. My father of a great Yokai named Inu No Taisho, and my mother was human.
Itachi- Interesting, in my world I was a Shinobi of the Konoha and achieved the rank of Jonin and joined the Anbu Black Ops that work directly under the Hokage; leader of the village.
Erza- I was a wizard in my world and belonged to a guild named Fairy Tail. I had many adventures with my friends and achieved the rank of S Class.
Inuyasha- Sounds like you're quite the badass.
Erza- Thanks. What's that in your hand?
Inuyasha looked down at the rusty and tattered blade in his hand
Inuyasha- This is Tetsusaiga my sword left to me by my father. Something feels wrong with him since I'm not sensing any Yokai energy. Something different is pulsating from him.
Man in shades- That is reitsu my good man.
Erza- Who are you and where the hell did you just come from?!
Man in shades- My name is Oetsu Nimaiya and I'm one of the members of The Zero Division. I am the God of Sword and the man who created the Zanpakuto. I'm here because I sensed an unusual aura with that blade you call Tetsusaiga. Reitsu is coming from it but it's also emitting something minor.
Inuyasha- It must be Yokai energy but I can't really feel it. It's as if something else is blocking me from sensing it. Must be this reitsu you speak of.
Oetsu- Precisely you're not used to feeling it so it's impairing you at the moment. As for you miss you seem to have some power in you as well that is withering away.
Erza-It's my magic. I was a S-Class Wizard of a Guild named Fairy Tail and my power was requip and could make armor.
Oetsu-I see I see that power is being transformed in to reitsu. Same with you crazy eyes your strange energy is being converted as well.
Itachi- I possess chakra as I was a shinobi of the Konoha.
Oetsu- Chakra?! I wonder….Come with me all of you. We're taking the stairway to Heaven so to speak.
Erza- Where to?
Oetsu- The Soul Palace particularly my domain. I will create a Zanpakuto for you Erza, convert your Tetsusaiga, and present one to you Itachi.
