Thanks for the chapter!
Hate to burst everyone's bubble but she's not on to him. If she had been she'd have attacked him rather than admiring him for being such a cute girl, especially considering how she feels about men in general. Most likely she's making sure he knows how to watch out for demon cultists so doesn't get kidnapped and/or corrupted by them. Although that picture of him is way too accurate to be a composite sketch. Either someone with a good memory saw him leave his father's place or more likely got sold out by somebody unless one of his relatives who were nabbed happened to have been carrying a picture of him. Although most likely sold out considering they know his identity, clothes being worn, and appearance and that he'd be in the area of the school at that time.
