Here ya go Sam! C5 just for you! I know it's not exactly the Artifacts, but it's right after the Artifacts.

C5: Rya vs. Kurama

As one thing led to another, Rya came upon Kurama after his mother is back home. She speaks from the shadows.

"You realize that was stupid."

"Rya."

"Kurama."

"What is wrong with you? What has caused this coldness in you?"

"What hast caused thine weakness?"

"We do not have time for idle chatter. I must flee."

Kurama ran towards the warehouse. Night was falling and there was no mistaking the scent. It was Hiei's demon form.

"You are not getting away from me Kurama! Hiei was right! You are spineless! Crystal Rosewhip!"

Rya pulled out her trademark weapon and started chasing after Kurama. She followed him all the way to the warehouse. When she sees Hiei stab Kurama she gets mad.

"Hiei! You will pay! He might be human, but he's still demon! It's the detective you want!"

"Rya?!"

"Rya? Hey why the hell does she look like me?"

"She is your sister. Didn't you know that?"

"No, Kurama, I didn't."

After the whole incident, and Yusuke, Botan, Hiei, and Keiko leave, Rya heals Kurama.

"Why did you heal me?"

"So that you can be healthy enough to face me!"

"Wait Rya! Why? Why must you fight me?"

"Because! You said awhile back…"

"Yes. And you looked really funny back there when Hiei mentioned Chapter Black."

"I did?"

"See? I was right. Now why don't you hand over your copy."

"I got tired of watching it, and destroyed it."

"Rya, why don't you come with me?"

"No! Crystal Slash!"

"Hey!"

"Fight back!"

"No! Something is wrong with you and I intend to help you, not fight you."

"Then help me by fighting!"

"Grrr…"

Just then, Koenma's form appears in the sky.

"Kurama. You are needed here in Spirit World. Rya, stop distracting him."

"Yes Koenma-sama." She looks back at Kurama. "I'll get you if it's the last thing I do!"

"Rya-chan, if that's how you want it, so be it. But I will help you back to your senses."
