[Sen smiles.] Don't worry, I will. [Though she'll probably wind up picking up a small paper fan and thwapping him if he acts out of hand before she runs tattling to Yamato. It always worked for keeping unruly demons in line. Thwap, thwap.]

—Ah? [Her eyes widen in brief surprise. Neither offer - not the lessons nor the protection - is something she'd expected out of this discussion, and it actually does catch her by surprise that he would make them in the first place.] That's very kind of you...

[Generally speaking, she does prefer to believe in the best in people. But, being in the position she's been in her entire life, she knows that humans and demons alike aren't necessarily good at heart. It's why, back in Japan, she had been so insistent on looking after Chizuru. People like that girl are very, very rare.

And people like Yamato are rare too.]

...I wouldn't want to burden you with such a thing... but it would be foolish of me to turn you down. [She clasps her hands in front of herself and bows to him in gratitude.] I'll do my best to learn from you, and I'll be depending on your protection until such a time when I'll be able to truly look out for myself.
