Chapter 1: The Demon and the Angel

Sesshoumaru was walking along the path leading back to his territory returning from his meeting with the lord of the North, a very boorish bull youkai who wanted a consolidation of their lands. Sesshoumaru had to do a lot of politicking to get out of mating with the bull's daughter as a means of their two houses combining and was in an extremely foul mood. He was hoping the bull would not try to plan an attack as he probably hadn't been as diplomatic as he could have been. He shuddered remembering what the cow had looked like.

He stopped suddenly, feeling a powerful aura and unsheathed Toukijin, unsure of where the threat was emanating from. The aura was one he had never felt before, not demon and not human but definitely belligerent.

He used his senses to their full abilities to try and track it, zeroing in on it in a few moments. He looked up and saw above him a woman, white hair as long as his curling around her as the wind played with it, caressing it. Her clothing was a long, flowing white robe almost indecently see though, open to her navel and as she touched down he saw she was just slightly shorter than him, maybe by only an inch or two. She stared at him, her eyes the color of quick silver, just as cold and unfeeling as his gold ones that regarded her with an emotionless glare. The biggest thing that he noticed about her was her huge white wings spread out behind her. She tucked them close to her back as her bare feet touched the earth, the tips of the long feathers only a hairs breadth from the ground.

Sesshoumaru's eyes widened as he recognized the apparition, Tenshinoyounashoujo. He had heard of these beings before. He gripped Toukijin tighter as she reached behind her and unsheathed the sword from her back.

"I am Mitsukai and this is Ingatekimen," she said, as she pointed the swords tip at Sesshoumaru's heart. "I will take what your father has stolen from mine"

Her tone of voice was dead pan and emotionless but Sesshoumaru could feel her anger coming off her in waves. He had no idea of what she could be talking about; all he knew was that she had just called his father a thief and that disrespect he was not going to allow.

He leapt at her swinging Toukijin and clashed with her Ingatekimen, the two sword's energy flashing like lightening as they collided, repelling the two fighters apart. They stood again staring at each other menacingly.

"The Tenseiga, I want it," she demanded fearlessly.

Sesshoumaru said nothing as his eyes narrowed dangerously as he threw out Toukijin's energy at her. With a wave of her sword she easily repelled it back at him, Sesshoumaru having to twist sideways to avoid his own attack. She then unleashed her own energy wave and let it barrel down towards him. He brought his sword up before him and the sparkling blast was reflected to the side causing half the trees to disintegrate.

They carried on this way for hours, neither able to get the upper hand on the other, too evenly matched in their abilities. The area around them looked like a nuclear bomb had gone off; there was nothing but destruction and devastation, both were panting hard at their exertions. Sesshoumaru saw her sword hand shaking, Mitsukai saw the sweat drop from his brow and run into his eyes.

"What is this about?" Sesshoumaru asked, realizing that to continue to fight would be useless.

"The Tenseiga it is the sword of heaven, your father stole it from mine. I have come to lay claim on my birthright," she answered back coolly.

"This sword is made from the fang of my father," ground out Sesshoumaru "My father is no thief!" he yelled suddenly, striking out at her with Toukijin again.

She again blocked it effectively and the two combatants stood almost nose to nose their swords crackling energy beams between them.

"Is that what he told you?" she whispered sarcastically. "Tenseiga is made from the wing of my father, it was not meant for demons like you." The malice was dripping from her voice like rain.

Their energies pushed them apart again so they were standing a few feet away from each other.

"Do you not wonder why it will not cut for you?" she asked unpleasantly.

Sesshoumaru didn't deign to answer her, but she had piqued his interest. How could she know this?

"It will cut for me as I am a daughter of heaven; the sword will do many things for me; I am its rightful owner." She said this with her head held proudly in the air, trying to look down her nose at the slightly taller demon lord. "Give it to me and I will prove the truth of my words," she ordered, holding her hand out as if her command was meant to be obeyed.

"Do you think me a fool? Give it to you so you can just take it? I do not think so." He gave her his small deadly grin and she returned it with one of her own.

"This is useless we can not beat the other." She stood and pondered a bit," perhaps you would agree to a trade?" she asked coyly.

Sesshoumaru said nothing as he continued to look at her with his cold golden eyes wondering what she had in mind. He was not going to give up the Tenseiga no matter what she said, he was only trying to buy time to find a weakness in her that he could use to his advantage, so far he had found none.

"I could give you your arm back," she stated, watching him with her metallic silver eyes for his reaction.

"No, been done, I have no interest in another arm," he replied as he tried to circle around her and get a bit closer for a good attack.

She circled with him as if they were partners in a dance also looking for an opening. If I could touch him I would know his deepest secret wish, I must get closer. Her eyes slid closed sensually as a thought came to her and she lowered her sword just enough for him to see an opening.

Sesshoumaru took it, and leapt forward bringing Toukijin to bear upon her. Just before his sword could strike, she moved impossibly fast and grabbed his wrist halting its momentum.

His eyes opened in surprise at her speed and strength. Never before had he not been able to best someone in battle and he was beginning to respect her abilities.

Mitsukai also was beginning to enjoy this fight. Any others she had been in were over all too quickly and there seemed to be nobody to challenge her.

As she stood there holding on to him she could see all the wants and desires he had within his heart in seconds. She smiled. "There is another sword you covet," she whispered almost sweetly, as she released him and flew back away from him with a beat of her wings. "I could get it for you."

"I can get it myself," he retorted, wondering how she had known about the Tetsusaiga.

"You haven't been able to yet" she mocked him. "Perhaps if we pooled our resources you would be able to acquire this sword in exchange for the Tenseiga. You believe it to be useless do you not?" She asked this question with some anger.

Sesshoumaru could see that she did not see the Tenseiga as useless but there was no way in hell he was going to be handing it over to her.

He thought about her proposal, he did want the Tetsusaiga and had tried numerous times and failed to retrieve his fathers other sword, even losing his arm to his uncouth brother, much to his own shame. I will allow her to aid me in retrieving the Tetsusaiga from Inuyasha and then I can destroy them both.

"I will allow this," he stated regally as he turned his back to her and began to walk away expecting her to follow.

The arrogance! How dare he turn his back to me? Her eyes narrowed in indignation and anger. He will regret this insult. She said nothing of what she was thinking only sheathing her sword and following the demon lord towards his brother.
