Makai Ouji: Devils and Realist
William Twining lives a charmed and privileged life. As a rich nobleman from a prestigious house, he trusts his superior intellect and strictly-scientific mind will help him sail through school with ease - but what he didn’t anticipate was returning home to discover his family went broke and moved out, leaving him penniless! Desperate to find something left of value, he finds a secret room in the basement, accidentally summoning Dantalion, Grand Duke of the 36 Armies of Hell in the process! All William wants is to be left alone to his studies, but he’s now tasked with deciding who the next ruler of Hell will be, much to his annoyance. With Dantalion and other demons eager to influence his choice by whatever means necessary, what’s a nobleman to do?
