DNA²

In the future, overpopulation is a serious problem. It all stems from the "Mega-Playboy" who passed his playboy DNA on to his one hundred children, who in turn had one hundred children each, and so on! Karin Aoi, a DNA Operator, has traveled back in time in order to change the DNA of the original "Mega-Playboy"--but is Junta Momonari really him? He can't even look at a girl without throwing up!

Karin's job well done has turned into a disaster! The DNA Control Medicine was supposed to rid Junta of his lady-killer genes, but instead she's accidentally forced him to become the legendary "Mega-Playboy"! Worse yet, he's already begun his conquest, starting with Tomoko, the most popular girl in Junta's school. But Tomoko's already got Ryuji, and her boyfriend's not afraid to let Junta know it

Junta's "Mega-Playboy" DNA hasn't stabilized yet. One minute he's suave, and the next he's struggling not to puke on a girl's shoes. Before the DNA can take hold fully, Karin launches a plan involving Junta's childhood friend, Ami. Could it be that the Mega-Playboy's charm doesn't work on everyone?

Hearts are aflutter and emotions run high as Junta's "Mega-Playboy" DNA starts coming into its own. But while Ami, Tomoko, and even Karin struggle with their feelings, Junta's made up his own mind. To express his true feelings, Junta plans to buy a present to give to the girl he loves. But who's the lucky girl?

Ami's friend Kotomi has a crush on a boy. Unfortunately for everyone involved, that boy is Junta. With yet another heart added to the mix of bubbling romances, Karin becomes desperate to get Junta together with Ami, the only girl immune to the Mega-Playboy's charms, and the only one that might tame the lady-killer-to-be.

After humiliating herself, Kotomi runs off and completely changes her image. Her new look is red hot, but Junta still isn't interested--until he realizes that the two of them are more alike than he thought! Can Kotomi press her advantage enough to win the heart of the budding Mega-Playboy?
