Kaburaya Sosuke, an impoverished detective, met Sarah, a princess from another world with magical powers. Sarah began living with Sosuke, and she quickly adjusted to life in modern Japan. Meanwhile, Livia, a female knight who came from the same world as Sarah, found herself lost and homeless, but surprisingly enjoyed her days here. These two people, who live a positive life despite their situation, began to have an impact on Sosuke and the other oddballs in the neighborhood, including a devilish lawyer, a divorce agent, and a cult leader.
