I understand the trepidation, but it's not completely unbelievable,  seeing as we have a succubus with a suspicious past, being presented as the normal understanding of that race, which are commonly known to lure people astray, as well as a weapons smuggler, a very serious crime in most cultures. Not saying anything bad about these characters, I'm looking forward to interacting with the, just pointing out that it does seem very possible for the school to take in dubious people. Still I haven't really been against many of the  corrections I've been asked to make.
