Many miles away from the village Inuyasha was taking rest in, way past the mountains, there was a castle. A dark castle with an ominous fog surrounding it, and the strangest thing was that the humans who inhabited it didn't seem to notice that clearly this was an evil and inhuman place to dwell in.

Now there was a room in this castle where their Lord resided. This room was to never be entered by even the guards or messengers. At this moment, the young Lord Tatewaki was watching a mirror in that room, held by a little girl who had a vacant looking face.

"What is this all about, Kanna?" he asked her.

She continued to stare blankly ahead. "This is Inuyasha and his new companion." She whispered.

"Interesting…" The young Lord looked at the mirror closely. It began to close in on the new person. It was plain to see that this was a young demon girl, a little younger than Inuyasha, and she resembled him very strongly. Ears and all.

"Could be his sister." A young woman holding a fan walked up behind the Lord. "Or his daughter. Or his cousin, or his mother."

"Could be anyone." The Young Lord shrugged. But something in him froze as the girl stared intently right into his eyes. It was only for a second, although for that one second the Lord felt something formerly absent from his lifestyle… A feeling that made him feel cold and fearful all over.

"I have seen enough, Kanna." He said, straightening up and adjusting his expression.

"Who was that girl?" The woman with the fan asked, "She looked like Inuyasha, but she looked directly into the mirror. How could she do that? She had no idea we were watching."

Lord Tatewaki paused. Then he smiled as if something had just came to him. "She is something else altogether, Kagura…"

"What do you mean by that?" Kagura asked.

"Nothing. I just… remember where I saw her before…" Lord Tatewaki sighed, "So long ago…"

Earlier that morning, Inuyasha and his friends had just left the village. His younger sister Inukasumi was still hugging him and spinning him around, humming a tune no one knew the words to. Or cared, for that matter.

"Ok, Inukasumi, this is getting a little annoying." Inuyasha moaned as she continued to dance and hum and whirl him around.

"Sorry, Oniichan." She grinned, "It's just that today is such a nice day."

"So you get crazy when it's nice out?" Inuyasha said, trying to shove her away.

"Inuyasha!" Kagome scolded, "You can't say things like that to your sister!"

Inukasumi giggled uncontrollably and pushed her brother away, twirling over to Miroku.

"Dance with me, O lecherous one." She ordered.

"Well, im not one to refuse a lady's request," he smirked, allowing her to skip along with him.

Sango laughed at the two, especially when Miroku tried to grab Inukasumi, but she kicked him in the shins and he fell to the ground clutching his leg. Yes, even Sango was starting to warm up to Inuyashas little sister and her happy-go-lucky ways.

"Things have gotten so much more fun around here now that you're here to play with us, Inukasumi." Shippo smiled.

"And a whole lot more nauseous, too." Inuyasha said dizzily. Kagome rushed to his side before he could loose his balance.

"Yes, Inukasumi, but you have to be careful with us." Kagome warned, "We aren't as strong or tolerant to spinning in circles repeatedly as you."

"But big brother is stronger than me!" Inukasumi stated matter-of-factly, "He's my big brother, after all!"

Inuyasha turned his head around so nobody could see what he was thinking, although all of them were pretty much thinking the same thing.

"Come on, Inukasumi," Shippo laughed, "You're a full demon! It's only natural that you are stronger than Inuyasha. I mean, duh!"

Inuyasha socked Shippo in the face. "You're a full demon and im stronger than you. Oh, I know why… you're a pathetic excuse for a demon."

"Stop being so mean, Inuyasha." Kagome uselessly tried to reason with them.

Inukasumi giggled nervously. She wondered if she was stronger than her big brother. It didn't matter to her; she loved him all the same…

…Inukasumi stopped abruptly. She looked frantically into the trees and gasped; something was watching her. She could have almost sworn she looked right into some things eyes, but the presence was gone almost as soon as it had come.

"What's wrong, Inukasumi?" Miroku asked.

Inukasumi shivered with both fear and the sense of protection. She inched closer to her brother and latched onto his right arm.

"What's wrong, sis?" Inuyasha asked, "Did you sense something?"

"I don't feel anything." Kagome said.

"Me either." Miroku added.

Inukasumi squeezed Inuyashas arm tighter. "I don't think it was anything." She said.

"Than why are you acting so weird?" Inuyasha asked, "You know, not spinning in circles weird, but weird weird."

Inukasumi was silent for a moment. Then she finally whispered, "Don't worry, Oniichan. I'll protect you. Just like old times."

Inuyasha scratched his head in confusion. Nobody noticed that a menacing looking wasp was flying out of its hiding place in the trees, towards the mountains where Inuyasha was heading to find Naraku, or whatever young Lord the demon was impersonating recently...
