Sosuke is a hardworking private detective who's down on his luck, but he'll be working even harder after he catches an (un)lucky break—an otherworldly princess who falls from the sky and takes an interest in his occupation.

Sara begins helping Sosuke with his detective work, and Livia is still making the best of life on the street while looking for her princess. It's just a shame that her best, well, isn't very good.

Livia faces a desperate struggle concerning her diet. A certain organization also takes an interest in her. But surely they can't win her over with the promise of food and housing... can they?

Sara takes an interest in all things preteen on Earth, while Sosuke begins to wonder what exactly she's doing on Earth. But the case at hand comes first! Can he puzzle out both at the same time?

Sosuke introduces Sara to the wonders of breakfast in Gifu, along with a spot of karaoke. Meanwhile, Livia discovers the refreshing power of a good public bath... that is, before she gets caught up in another unsavory job.

Noa continues her devout pursuit of Livia's holy body with perfectly wholesome interests at heart. Meanwhile, Puriketsu continues to dream of making it big with a band. Is there a way Livia might be able to help?

As the weather turns chilly, Sosuke introduces Sara to a special wintertime treat. Then they're off on case that's going to take them in circles and give them a run for their money, you could say.

Sosuke's quest to get Sara into school continues. The question is how to get a princess from another world the paperwork she needs, and Sosuke may have just the family connection to get the job done.
