Devils x Dragons x Dad

A popular, but normal, Biology teacher at Kuoh Academy. Or at least that's what Rias Gremory used to think of the man. And yet, as she sees him healing a dying Hyoudou Isane, the threads holding the secrets of the man begin unraveling one by one. --- Author Note: 1. It will take some time to get to know the protagonist's past. I ask for the readers' patience. Also, it seems like I'll probably be writing the story through the eyes of other characters. 2. I pretty much wrote this story with only the protagonist's backstory planned out. The rest of the stuff I'm making up as I go along. I hope everyone has fun reading it. Sorry if any characters seem OOC. 3. Also, gender-bent characters. Why? No reason really. Just felt like it.
