In this world humans aren't dominating kind. There's many kinds that are important: humans, vampires, angels, demons, werewolves, aliens (it's rather offensive phrase now), fairies, kitsunes, and many, many others. And after years of wars they were finnaly living in relative harmony. So schools for kids of diffrent kinds are created all over the galaxy. And you just joined one of them "Hey, you're new one, right? I'm Levi, Levi Ackerman, a demon. And don't worry about my age, demons are old but they need more time to develop." He seemed to answer all questions that showed in your minds, before you could even speak "Oh, sorry, I'm forgetting to not read peoples minds. So, what's your name, new one?" He was talking without many emotions
