I honestly Didn't know Ryuu meant Dragon haha, I was thinking of it because I remember a mention somewhere that his abilities had to do with fire, and he's old, and being our enigmatic teacher I assumed he wasn't one of the species we can choose from and I love Dragons, thus my theory wish was born.
Love in the Youkai world...Love in the real world seems like it couldn't possibly be more complicated already, until you look at almost ANY other universe.
Considering that the school has a Neko-Girl fanclub, the complexities increase. Also its hilarious.
First just having a Neko fanclub would slightly off, mostly if the members were only Neko (though I assume not). That would be like if Americans had a japanese fan- oh wait (weebus). It exists in our world, not really strange.
But then you say Neko-
Girl and suddenly its a new ballgame. Now there is an air of racism and sexism in the same place. I find it actually very funny to think of such a club in real life, where you basically worship a specific gender of a specific race. (Actually, I hear that Japan has girls who are completely infatuated with foreigners, so maybe the race/gender thing does exist. The fact that each time I've heard of this, the person telling me about it did not mention exactly how sexist the practice is (and possible a double standard) I guess a Neko-Girl club wouldn't be odd, its still weird though.)
All in all, the club should be much more prominent, and much more hilarious.
