"It's kinda complicated," Kosuke said slowly, "but I'll try to explain it." He paused for a moment, grasping for the memories. "I was born as a human, but not long after a low level demon came and attacked my mom. She couldn't see it of course, but she managed to fight it off anyway. It was wounded and in order to stay alive it possessed my body for one week before it left again. I have almost no memory of what happened during that week. But in that time it released a significant amount of demon toxin into my small body, and I was quote on quote 'impregnated' by it. The word sounds funny but it's not. It means at some point you'll start to turn into a demon. From that moment when you reach 1% demon, it's impossible to reverse the process, but you can slow it down, and at 99% it's possible to stop the process all together, but you have to stay completely pure and innocent. It's around 98% that a person develops demonic characteristics, so I haven't been this way for very long." He looked down, "I've kinda lived my life just pretending it wasn't happening, living as a human, so that's probably why I'm not like other demons... I just don't consider myself one. But honestly, I'm not sure if I could stay this way if I ever lost that one percent of humanity inside of me." He smiled and rubbed the back of his head, "But I'm not gonna lie, there are some perks to the deal, even if they are few and far between." The bird on the girl's hand was edging its way closer to Kosuke, as if its curiosity was far surpassing it's fear. It looked about ready to just hop on his shoulder...
