Something draws Ria's attention

As the night wind blew across her perfect skin, Ria soared in the direction of the Emiya household. But as she flew, she felt something off. It was like something was watching her. Ria stopped and hovered there.

That's odd, she thought. There should only be a handful of people who could see me, and I doubt they are watching the sky right now.

Looking around, she felt the watcher coming from a near by mountain. I guess I will check this out first, she thought as she shifted her body to fly towards the mountain.

As she drew closer, she could tell whoever was watching her was inside the mountain. She could sense a magical barrier between her and the voyeur. She floated towards the barrier and found that it was hiding a cave. From within the cave, she could feel some odd magic.

Ria, still wanting to know who was watching her, continued into the cave. After flying through for a while, she came out into a massive chamber. It was filled with a reddish light, with a giant pillar in the middle. On top of the pillar were three spires. Directly above the pillar as a single floating sphere. Moving closer to the pillar, she could make out something that looked like a creature inside it.

Before she could get any closer, a voice called out.

"Ara ara. So you noticed us," a pleasant sounding female voice echoed in the chamber.

"Not another ara ara", Ria muttered to herself. "I was surprised that someone could see me," Ria began. "So who are you?"

The voice chuckled. "I'm afraid there is no easy answer to who I am," the voice from directly behind Ria.

Turning around quickly, Ria saw a woman with long, white hair, pale skin, and red eyes. She was wearing a sleeveless white dress, with gold and white shoulder bands. She had some resemblance to me, but not as sexy, Ria noted.

But what was odd to Ria was that she could not see the woman's name. Normally, my Erokami eyes would show me their name.

"As for how we can see you," the woman continued. "I believe it was because we touched that notebook."

Ria was puzzled. "Wait, I don't remember see you touch the notebook."

The woman smiled. "I'm not surprised you didn't notice me. After all, parts of me were inside the body of Sakura Matou."
