"I'm a vampire."
Oh, joy. We've been led on by a bloodsucker. At least Reiko didn't look ready to burst into flames anymore. Quick to anger, quick to calm, as she'd put it. She still didn't look particularly happy though. How could she be, really? She'd still seen Yoshida kill one of the people she was trying to protect, and how the hell was she supposed to compete with a vampire if it came down to having to fight? For all her talent with a shinai, she was still only human. Maybe it's because of this that she said what she said next.
"If you need blood, I don't mind offering up a little bit from time to time. Just don't kill anybody else, don't make more bloodsuckers, and get us out of here. I can't see me getting along with a vampire - I still don't fully believe they really exist, much less that you're one - but we humans do what we have to in order to stay alive." Survival was the basest human instinct, even if it meant doing something they didn't like. The expression on Reiko's face made it perfectly clear that if given the choice, she'd much rather not team up with this girl, but she was pretty much the only way to keep on living right now. Reiko found a small bit of ironic humor in that their best bet for survival was to trust a girl claiming to be a vampire.
"But keep this in mind," Reiko added once it crossed her mind. "I'm not a big vampire fan, but from stories I remember, they're notoriously good schemers. If I find out you're leading us to make some kind of feast for yourself, sunlight will be the least of your worries. Got that?"
