Don't be daft. You know I was talking about the age and power gap, not the species difference.
There's nothing wrong with a good monster girl romance.
My critique was of the author, not the story. This is obviously a romance manga; we all know where it is going. The mere fact that someone considers "middle-aged teacher falling in love (/lust) with his adolescent student(s)" a good story to tell, that's the problem I was arguing against.
Well, would that be set in a real-life-ish setting, argument would be more valid.
This one? Eh, fantasy world(with not yet stated morals)+basically interspecies relations? Too many hoops to jump through for a direct comparison, IMO.
Unless you view all fictional equivalent to real, in which case, god bless your unending fight for moral high ground, cus I won't.
