I'm still a bit unsure what he can actually offer people..? Like... Can I say that since he's off brand Bakura and of course he has he and his occult obsession means that he knows how to make wards and charms and all that such?

Also is there something that is student-only accessible, like campus email or something where he can do an advert just to students, rather than something Mr. Nosey could see walking through campus? Possibly some trick he knows to make a sign only noticeable to students and not "adults"?
