Keiichi Morisato is a shy student who serves as an errand boy for his roommates. One day he tries to order some food, but accidentally dials the goddess help line instead! A goddess named Belldandy arrives and tells him she will grant him any wish, but only one wish. He doesn't take her seriously, thinking his roommates are playing some kind of prank on him, and decides to play along and call their bluff. Being unpopular with the girls, he wishes to have someone like Belldandy stay with him... forever! Much to his surprise, Keiichi's wish is granted and Belldandy herself will stay with him forever; and that's where the trouble begins. Women aren't allowed in the dorm, and the magical force that granted the wish won't allow them to be separated. As if things couldn't get worse, Belldandy's sisters begin to show up as well!
Several of the characters are very similar to ones in the other series, the action/comedy nature of both is the same, as is their largely episodic nature. Not surprising since both series were created by the same person. Nonetheless, if you enjoyed one you'll also enjoy the other.

Both manga focus on a pair of female cops, with one officer in each pair being a new recruit. The cops in question are often as wild (or wilder) as the criminals they combat. Both series have a lot of action and a lot of comedy.
