Sakura
"Away where?" Sakura replied, rather concerned at the manner in which the girl had dragged her off her feet.
Ultimately, though, Sakura knew that, if the girl actually wanted to harm her, there was very little she could do about it, and she didn't seem hostile, so she made no effort to resist despite the lack of an immediate answer to her question, instead simply holding on as the girl carried her through the forest, listening to the girl's chiding with ever-increasing horror. The thought of being turned into a pleasure slave by some vampire sent shivers down her spine, bringing back bad memories of her past abuse, and she couldn't help but wonder how close she had been to such a fate, and whether she would have left the forest quickly enough to escape his attentions. As she clung to the girl, she began to realise that her trip had been reckless, that her preparation was not sufficient to travel this deep, even with her ability to escape via her shadows.
Finally, after a significant trip, they arrived at the girl's destination. Still unable to see in the darkness, Sakura could only tell that they appeared to be inside a tree, perhaps some kind of hideout. Before she could ask any further questions, however, the girl pressed a vial into her hands, informing her that it would let her see.
"Thank you", Sakura responded, holding onto the vial carefully.
For a few moments, Sakura hesitated, unsure whether to trust the strange woman, before quickly deciding that, if the woman truly wanted to harm her, she could easily have just forced the potion down her throat, or done anything else she liked. So, taking the vial, she tipped the contents down her throat. Almost immediately, her vision began to improve, allowing her to determine that they were, indeed, inside a tree, in some kind of hideout. What was more, she could now see her saviour more clearly. As Sakura had already determined, the girl was lithe and short, with only a modest chest. But the ability to see allowed Sakura to notice the girl's white hair, green eyes and, most surpisingly, her distinctive pointed ears.
"Yes, I can see much better now", she said with a smile, only a slight hint of the surprise that she felt appearing in her face.
"My name is Sakura Emiya, it's nice to meet you", she added, bowing politely. "Thank you again for saving me. I wasn't intending to go this deep, but I got a bit lost, and I was too focussed on my search to recognise the danger I was in."
