Junta's great granddaughter goes back in time in order to make Junta stay as the Mega-Playboy so she can continue to exist. Along with her comes an old man with the intention of making Junta stay as the Mega-Playboy forever for his own purposes.When Junta starts getting attacked, he has no choice but to return to being the Mega-Playboy in order to protect his loved ones.

Karin, a DNA operator from the future, is on a mission to change the course of History by stopping Junta Momonari from becoming the Mega-Playboy who fathered 100 children and led to the overpopulation of the world. But Junta is no playboy; in fact he is allergic to girls. But when Karin shoots him with the wrong DNA-altering bullet, he starts sporadically becoming the Mega-Playboy capable of charming any woman. Karin must try to restore the situation to normal before the change to Mega-Playboy becomes irreversible.

In the future, society has a major population problem. The cause is the Mega-Playboy — men who are totally irresistible to women, due to their genes. One Mega-Playboy can make over 100 women pregnant and the male offspring in turn also becomes Mega-Playboys. Karin is an agent sent to the past to find the first Mega-Playboy and stop him with a special genetically tailored bullet. Karin, who dreams of having her very own "Sweet Home" (a rarity in the overcrowded future), finds the original Mega-Playboy — a young man named Junta. Junta has a problem; he throws up at anything even remotely sexual. Perplexed, Karin tries to complete her assigned job anyway, which goes badly wrong. Other players in this twisted plot are Ami, a girl that Junta grew up with (and the only female he does not get sick around), Tomoko, first victim of Junta's Mega-Playboy powers, and Ryuuji, the jealous boyfriend. Not to mention the hordes of girls who swoon when Junta powers up, including Karin.

After a meteor hits Earth, traitor forces have (for all intents and purposes) taken over, and the people are suffering. In the chaos, a boy named Tetsuro Daiba, who had lost his parents in the meteor hit, is paid a visit by Mello, a mysterious woman appearing in a bright light. When Daiba comes to, he finds himself in a spaceship infirmary under observation. Stealing a fighter that he didn't know how to pilot (until he tried it), he breaks out, flying like a total pro. He was able to remember how to pilot from his DNA memory... and to find out more, his doctor friend takes him to his secret underground lab, in which he acts as a professor to find out ways to stop the traitor regime. When the forces invade to take him back, a girl named Rei Yuuki mysteriously shoots down their entire carrier with only a fighter jet! Apparently, both have mysterious powers that the enemies want, which may or may not be connected to their being the only two known survivors of the meteor impact. While looking for a third survivor (which turned out to be a cat), the two are taken by force to Queen Photon (ruler of the traitor regime), who claims that she is out to SAVE the Earth from those who sent the Meteor. The two don't know whether to believe her or Mello until the (telepathic) cat breaks them out of the Queen's sealed chamber, and Mello comes to straighten things out. That's when the two (er, three) of them make a choice... Stay on a planet that can't support their advanced race, or strike out into the unknown of space?
