Hanekawa herself is a pretty normal human so go ahead. Schuldig will probably be able to find out she lives with Aya as well as her family troubles.

If he tries to read for too long he might get pushed out by Black Hanekawa, a bakeneko (http://en.wikipedia.org/wiki/Bakeneko) who lives inside Hanekawa's body via a split personality disorder. She wouldn't want someone sneaking around its mistress's head.
