吾妻薫

One of two men who breaks Marika’s fall when she drops from the sky, Kaoru invites this otherworldly princess to live with him. He then invites this otherworldly princess to live with him. He's level-headed and a bit of a worrywart, but he has his ditzy moments now and then. Unlike most modern men, Kaoru is incredibly strait-laced. After Marika kisses him, he becomes convinced that his only option is to marry her. [From MangaGamer]
