For some individuals, baseball is more than just a game. Momokitchi Momoi, an underworld boss and the owner of a professional team known as the "Peach Twisters," seems to be the perfect example. There is only one punishment for players who have let him down: death. Terrible as he may sound, there is someone even more wicked than him—his daughter, Momomi. The three members of the Danger Service Agency—Mikura Suzuki, Tomohisa Harada, and Kenichi Kurokawa—are tasked with kidnapping Momokitchi and taking down his criminal empire. Surrounded by armed bodyguards, he is bound to be a risky target. However, born with a gun in hand, Mikura is used to dancing with danger. The only unknown quantity is Momomi, reputed to be a cold-blooded killer with a twisted mind. Should she stand in the DSA's way, Suzuki might finally find herself a worthy opponent.

The story is set in the future on the planet named Amoi which is controlled by a supercomputer named Jupiter.

However, Iason keeps Riki longer than it is socially approved, and rumors abound about their possible relationship.

Two soldiers from warring countries are bound by a pledge as master and servant. Taki Reizen is a Commander of sublime beauty, shouldering the fate of his nation.

For all their genuine feelings, what will come of love made cruel by the violence of war?

On his first day of junior high, Kei Enjoji fell in love at first sight. His heart was immediately captured by the gorgeous Ranmaru Samejima, a young kendo prodigy, and the two slowly formed a deep romantic bond. Now adults and living happily together as a couple, things seem to be going well for Ranmaru and Kei. One morning, host Kei arrives home after a night out drinking with a client. A frequent occurrence, Ranmaru is initially unfazed by Kei's drunken state—until he notices three extremely suspicious things: Kei's clothing smells of makeup, his chest is stained with lipstick, and he is carrying matches branded with the name of a love hotel. To top it all off, a woman calls the apartment asking for "Kei-chan," and at that, Ranmaru loses it. Hurt by Kei's unfaithful actions, Ranmaru storms off. He spends the day reminiscing about years of precious memories, deciding to put them behind him for good—and when he is "picked up" by a woman on the streets, he comes to terms with reality. If this is what society wants, and if Kei has truly fallen for a woman, then who is he to stand in their way?
