While trailing someone, the poor detective Sousuke Kaburagi runs into Sara, an imperial princess from another world who uses black magic. Sousuke and Sara gradually begin living together, but in the blink of an eye, Sara becomes accustomed to modern-day Japan...

Meanwhile, Livia—a female knight who transferred to the world after Sara, is enjoying a surprisingly pleasant life, even though she is homeless. The two otherworldly individuals who live a pleasant and strong life influence Sousuke and the other oddballs who live here, such as a devilish lawyer, a divorce agent, and a cult leader.
