Maybe... but a good master takes the time to find out anyway.

[Maybe a little harsh, but a. still sure this isn't Raquel, and b. with how positively Naoto speaks of her, she would be the kind of master who'd at least know something, even if she was tsundere about it.]

How did you two meet then?

[Something that Naoto likely hasn't told her everything about yet, but something "Raquel" should spout easily.]
