A/N: Ok this is my first fanfic and my first crossover as well so be doubly nice please, I would be very grateful. Also I would like to warn you now that this story doesn't follow the Inuyasha series or the Harry Potter books even though it may seem that it does. It is based off of "what ifs". Now I know how Inuyasha's father died, but what if he didn't? Who's to say that this story wouldn't have happened? I'm just trying to clear things up here.
So if you are so into the series and books and think that that's the only way it happened then I respect that but I warn you not to read this because you probably won't like it. To those of you who have open minds and don't mind this story at all then be my guest to read and review you know, I was just getting a little annoyed with people not getting my p.o.v on this.
Disclaimer: I don't own any of the Inuyasha or Harry Potter characters used in this fic except for Nira and Akina Shizuki.
Prologue:Away in the land of Japan, demons live undetected by humans. They strive in the woods where they can live in peace. Humans have grown out their cities to the outer regions of the land, but demons still survive and grow unknown. True demons are more powerful and have magical abilities, but it is still easy to be spotted by a mortal. Nonetheless, these demons occupy the woodlands near the ocean on each point of the compass.
Through out the land, there are stories about a great Dog Demon General who is Lord over the Western Lands. These stories contain his victories in war and how he led his soldiers with bravery and confidence. Although, these stories don't tell about the Lords personal life for it rarely gets out. The only ones who could know this information would be the servants, but they hardly venture far. No one knows anything else about the general except how he acts during war.
This is a positive thing for the general because if anyone found out about him, they could tap into his weakness. The general was known as Inutasho and rarely showed himself in his human form. Everyone usually identified him as a giant white dog with acid saliva dripping from his mouth. As a human though he looked young: about in his late 20's to early 30's, but he was actually a thousand times older. He was slender but well built and always wore armor.
He usually had his long, silver hair in a high ponytail, to keep it in place during battle. His golden eyes shinned through the darkest night, as he gracefully sneaked around his land. He lived in a huge, white castle that contained rooms galore as well as servant imps; the imps were demons too but were much smaller and almost looked like frogs. One thing that dominated in the demon world was, that if you were a high-class demon in strength, then you were more likely to survive. Inutasho was well known as one of the four highest demons in Japan.
By his side was his beloved mate Akina. She wasn't a full demon and was almost always looked down upon. In this kind of world, full demons were seen as the most powerful beings in the world. Lady Akina was half Wolf Demon and half witch; she had brown wolf ears on top of her head, which matched her hair. Her brown wolf tail hangs at her knees as she moves or walks. She had all the aspects of a demon but also had the power of a fully trained witch.
Akina was the Lords third mate within his lifetime. His first love was his own kind, a full dog demon. They were happy together and even bore a son, Sesshoumaru. Inutasho's son was the spitting image of himself, he couldn't have been more proud. Unfortunately, Sesshoumaru's mother had gone out and had never come back. Of course there were stories that formed, but they were only lies. Not long after Inutasho fell in love with a human Lady. She was to be promised to a Lord, but it never happened. Inutasho had stolen her heart and in return she had bore him a son, Inuyasha. He had the same silver hair and golden eyes as his father, but had one big difference. He had white dog-ears on his head and his face held his mother's shape. Everyone could tell that he was only half. But, the general felt that he couldn't be happier, he had two wonderful sons and a loving wife by his side, but as it turned out, sadness found him again. His human mate had caught a sickness well known in her world; it affected the lungs and made her cough up blood. She also had other symptoms like a fever, swollen neck glands, and pallor or being markedly pale. It was a slow death for such a young women, but she finally was released into the spirit world.
This devastated Inutasho, he now had two sons to raise with out a mother's care. He did fine for being a single parent, but he knew that he needed help. As he was patrolling his land one-day he had come across a beautiful Wolf Demon. It was love at first sight for both of them, but sadly her parents didn't approve. They sent her away to a school for witchcraft. This is how Inutasho found out that his beloved was only a half demon, but to her surprise he didn't care because all he wanted was her. So he followed her every year to the school and kept an eye on her. He would also send her little things that told her that he still thought of her.
Finally, when she had graduated from her school, she announced to her parents that she was going to marry Inutasho. They were furious about this and forced her to choose between them and a happy life, or him and a life being shunned out of her family. It was the hardest choice she had to make, but in the end she had chosen Inutasho. It was a slow beginning for she missed her parents dearly, and wanted so badly to make them understand. It was also slow for the boys to accept her too; they played many pranks on her until they finally settled down. She soon got into the groove of her new life and quickly put her parents at the back of her mind.
Many years had past since that sad day and now Inutasho was the father of a beautiful baby girl, Nira. She had mesmerizing sapphire eyes, which seemed to hold her very soul. She had midnight black hair that fit neatly on her head. With it she had matching wolf ears, as well as a tail with red tips. Her fangs and claws could be seen quite well, even though she was still small. Inutasho was very proud of this and thought his life complete, he had three children, a beautiful and powerful wife, and the luxury of a Lord, who could ask for more.
As the children grew and developed Inutasho had special gifts for them. When they reached the age of 13 he would give them each a sword. This would protect them and make them stronger in battle. It was decided that Sesshoumaru would get Tenseiga, a sword that could heal 100 people in one sweep, Inuyasha would get Tetsusaiga, a sword that could kill 100 demons in one sweep, and Nira would get Tatusho (a.k.a. Tasho and Tusho), swords that could connect at the handle and help Nira learn about herself. Each sword had its purpose to its unknown master or mistress. Sesshoumaru's sword was to help him appreciate another persons life and to watch over his younger siblings, Inuyasha's sword was to help him in battle and not rely on his instincts for fear that he could kill him, and Nira's swords were to help her harness her unknown power.
Soon Inutasho got word of a deadly demon that was terrorizing all of Japan, human and demon alike. His general instincts kicked in and immediately rounded up his army for training. This would have been a good move except for the fact that he didn't know what kind of demon he was dealing with. This had been pointed out to him, but he didn't care, all that mattered was that his army was in tip top shape and was to be on guard every night and day.
After a hard day of training the troops the general headed for his study. He had a choice to make that would include his entire family. His oldest son had already turned 13 and was well into training with him and his wife. His other two children were barley 8 though, and with this new threat he would have to ante up the age for the swords. He had rocked his brain from hours on end about this, but he felt that it was the right thing to do. He decided to present the swords to them at 9 years of age.
