Four years ago, 10-years-old Kirigaya Kazuto ran away from home after finding out he was adopted, never to be seen again. Now, the world finds itself threatened by the Evil Minion Hordes of the Overlord 'Kirito'...who doesn't seem as Dark or Evil as he claims to be. But well, you all know what they say: "Evil ALWAYS finds a way..."
"A new overlady, you say? She's a little short, although her temper is impressively vile. Oh well. Needs must when needs must. Too long have the lands of Halkeginia gone without true Evil. There are fluffy bunnies and happy ponies all over the place, frolicking! It makes me quite sick! No, it doesn't matter if she wants to or not. Because Evil always finds a way."
