"Oniichan! Oniichan!" Inukasumi cried, "Come here for a second! Come here!"

About a week had passed since they had met Inuyashas half sister, Inukasumi. As the days passed, Inuyasha had realized his sister was a very curious girl, and that she didn't like to be away from him for long periods of time.

"Oniichan!" she called out again, "Come here, please?"

Inuyasha walked up to her from Kaedes hut. "What is it?"

"Come here, you have to see this. Um, close your eyes."

She grasped her brothers' hand tightly and led him off in her direction. Inuyasha, though with his eyes closed, could tell they were going farther and farther away from the village. He could smell water flowing…

"Here. Open your eyes." Inukasumi stated proudly.

He did. What he saw was a small stream.

"What is this place?" He asked.

"Let me give you a hint." She grabbed a stick and speared a fish that was swimming in the stream. She held it under his nose and said, "Demon parents who can find a mortal good and kind enough to marry are the best kind, in my mind."

Inuyasha thought for a second. Then it all came back to him like a flash.

"This is the stream you cooked fish for me by when we first met!"

Inukasumi clapped her hands and danced in a circle. "Yes, yes, yes!" she cheered, "You do remember!"

"Yeah…" Inuyasha thought out loud in a trancelike voice, "I didn't know the village was so close by…"

"Brings back memories, huh?" She put her hands on his shoulders and made him sit down. She snuggled up to him and closed her eyes.

"I love you, Oniichan." She whispered, "Im so glad I found you."

"You were pretty alone, huh?" Asked Inuyasha.

"Yes. When Myoga wasn't with me. Which was once in a new moon."

Inuyasha flinched.

"What's wrong?" She asked.

"I… I think you mean 'blue moon.'" Inuyasha smiled nervously.

"Oh. Right." She sighed.

"What was life like for you when I wasn't there to see?" He changed the subject hastily.

"It was very lonely. I didn't have anyone." Inukasumi paused. "Inuyasha…" Inukasumi asked cautiously, "Did Sesshoumaru… Or anyone… Drop any hints that I might have, you know, existed?"

Inuyasha thought. His father didn't leave her anything like he did with him and Sesshoumaru… or did he?

"My father did make three swords." He said, "Maybe one for each child? There was Tetsusaiga, Tenseiga, and Soounga."

"Soounga?" She asked.

"Yes, but it's gone now. We destroyed it because it was too dangerous."

"Too dangerous?"

"It was a sword of hell. Of world conquest. It possessed anyone who was too weak to hold it."

"Like you?"

Inuyasha looked away, saying nothing.

"Oh, what did I say! Im sorry. I didn't mean it like that." She apologized quickly.

"Maybe you were strong enough to wield it." Inuyasha said, "Your mother was a powerful demon, if what Myoga says is true, she was a match for even my father. In fact, that's how you were born."

"Maybe Soounga was his heirloom to me?"

"Could be. You are probably pretty strong. But why didn't he say to give it to you specifically?"

"Maybe he made it for me to find. Like you with Tetsusaiga."

"Even then, it was said whenever I was old enough I would find it and use it. Father never said anything about leaving Soounga to you. Or anyone, for that matter." Inuyasha said, "He must have just left it for Sesshoumaru and me to destroy."

"Perhaps… Father just made it for himself. One for him, and each of his sons." Inukasumi sighed, "Father didn't want anything to do with me."

Inuyasha didn't know what to say. He didn't want to lie—maybe what she said had truth to it. He squeezed his sister tight.

"I don't care what my old man or your mother thought about you." He said, "You're my sister. What they thought of you can't change that. I care about you."

Inukasumi buried her head in her brothers' embrace to hide her tears. "Stop making so much sense." She whispered.

"Where are Inuyasha and Inukasumi?" Shippo asked.

"I don't know. They must be off somewhere… Talking again." Sango said.

"Well, they do have a lot of catching up to do." Kagome said.

"I still don't know if we can trust her." Sango shook her head.

"If Inuyasha can, then we can." Miroku said.

But Kagome remembered how Sesshoumaru had tricked Inuyasha with a false version of his mother. He did get Tetsusaiga, eventually, but his mistake had caused himself a lot of pain, both in his heart and his body.

Kagome felt sorry for Inuyasha. Maybe he was so easily fooled because he was really lonely without his family. Sesshoumaru didn't count... Kagome suddenly felt very grateful for her mom, Sota, and gramps.

"It's so sad…"

"What was that, Kagome?" asked Miroku.

"Ah? Oh, um, nothing." She said, a little flustered, "All im saying is that I think we can all trust Inuyashas sister. She seems really nice."

"I trust her."

"Me, too!" Shippo said.

They glanced sideways at Sango.

"What?" She said nervously.

"Why do you not trust Inukasumi?" Miroku asked.

"I do! I…" She sighed. "I don't know."

"Why not?"

"Even if she truly is Inuyashas sister, I just can't trust someone that easily!" She cried, "She seems to be a good person, and Inuyasha can trust her, but…" She kneeled down to the floor and put her hands over her face.

Miroku sat down next to her. "I know. It's ok." He put his arm around her. "You have the right not to trust everyone you meet. You have been through so much, it's a wonder you can trust even me."

"Oh, Miroku…" She started, but then she realized what his right hand was grabbing.

"…I don't trust you!" She slapped him in the face and stormed out.

"Smooth move, monk." Shippo rolled his eyes.
