Alexei Barnes Alderp (アレクセイ・バーネス・アルダープ) is a former noble and governor of Axel. He is maligned by Axel's citizens for being greedy, selfish, and an utterly corrupt noble.
Alderp is middle-aged, balding, and fat, with an even more disgusting personality. He fits Darkness' descriptions of "ideal" marriage partner perfectly, aka scum of scums by normal standard. However, Darkness will never marry him, because he is rotten to the core, and willing to sacrifice anyone for his selfish gains.
Alderp's luck, perverseness, and cunning are equal to or possibly greater than Kazuma's own. In many ways, he is like the evil version of Kazuma, that does not care about his comrades or friends.
