Yuusuke was just an ordinary teenager attending high school when suddenly, Noelle stumbled into his life in a rather unusual way - completely naked and utterly innocent. Before he could even comprehend what had happened, Yuusuke found himself part of an extraordinary family of otherworldly beings. Papa was a Frankenstein monster who enjoyed exercising, Mama was a stunning woman with a fascination for "round objects," the eldest sister Sara was invisible, Gabriel was a teenage vampire with a bad attitude, and the youngest sister Ruka loved inventing things. There was also Grandma, a powerful witch, and her familiar, a vulture. All Yuusuke wanted was for Natsumi to acknowledge his feelings, but now he had an angel-in-training following him everywhere he went, along with Noelle, who also had her own guide on the path to becoming an angel - Michael.
