Papillon Rose (2006)

This is Gameindustri. Beings called Goddesses rule the countries of this unreal world. The four goddesses govern four states: Planeptune, Lastation, Lowee and Leanbox. For many long years these countries fought each other over the Share, the source of the Goddesses' power. However, fearful that the conflict would pointlessly erode their strength, the goddesses signed a Friendship Treaty forbidding them from taking the Share by force. Under the treaty, the Goddesses and their younger sisters took a step forward to a new stage in their relations. It is the dawn of a new, dynamic era marked occasionally by shared laughter, disputes as well as cooperation. But what does the future hold in store for Gameindustri...?

Struggling yet brilliant, 19-year-old Minato Sahashi has failed his college entrance exams for the second time, resulting in him being regarded as worthless by those around him. However, the course of his seemingly bleak future is altered dramatically when a beautiful, supernatural woman falls from the sky and into his life. That woman, Musubi, is a "Sekirei," an extraterrestrial with extraordinary abilities. Recognizing the potential of the Ashikabi gene within Minato, Musubi kisses him, initiating a bond between the two of them. This drags him into the high-stakes world of the Sekirei, where he and his new partner must compete against others in a battle for survival called the "Sekirei Plan." However, unbeknownst to the contestants, there is far more at risk that what the competition initially entailed. Manga series by Sakurako Gokurakuin.

16-year-old Hayate is really down on his luck. Because his unemployed parents are good-for-nothings who waste what money they have on gambling, Hayate had to start working at a young age to help out his family. Although such experience has made him inhumanly fast and tough and skilled at things boys aren't normally skilled at, it has also left him in an awkward position, as his parents have racked up such a huge gambling debt that they have sold Hayate to the yakuza for the value of his organs. In a desperate attempt to avoid that fate, Hayate decides to become a "bad guy" and kidnap someone to be held for ransom, but his efforts to do so are mistaken as a confession of love by the girl he targets. When he helps save the (as it turns out) ultra-wealthy 13-year-old Nagi from real kidnappers, she takes him in and gives him a job as her new personal butler (and love interest) until he can pay off his debt. But Hayate is more attracted to Nagi's beautiful teenage maid Maria, and head butler Klaus is initially disapproving of a boy with such a poor look. And then there's Nagi's pet Tama, who is also a force to be reckoned with.
