Salad Bowl of Eccentrics

Sousuke Kaburaya, an impoverished detective, met Sara, a princess from another world with magical powers. 

Sara began living with Sousuke, and she quickly adjusted to life in modern Japan.
Meanwhile, Livia, a female knight who came from the same world as Sara, 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 Sousuke and the other oddballs in the neighborhood, including a devilish lawyer, a divorce agent, and a cult leader.
