[The tone of his voice and the unpleasantness of his smile make Sen feel as though she's making some sort of deal with the devil, here, but what else is she to do? This isn't her home turf. It's Kaoru who has the benefit of experience in this place, not her; while normally she would certainly call him out for his... attitude... she doesn't feel as though she can do that here.

So she presses her lips together into a thin line and nods once, her brow furrowed.]

I appreciate your kindness.

[She'll owe him one, in the future. For all she knows that might be why he's helping her now - she's a resourceful person, and always has been; once she manages to establish herself here, she'll be in a position to repay him in kind. She wonders briefly how much of a debt she'll manage to incur before she can start to pay it back, then banishes the thought from her mind.]

You'll have to forgive me my rudeness, however - circumstances being what they are, I won't be able to bring you a gift this visit.

[If she'd known she was going to get hunted down by humans and wind up having to seek shelter in Kaoru's apartment, she'd have bought him some cosmetics as a gift or something. Maybe she can make it up to him by bringing him a corpse to eat later.]
