A fun sci-fi series about the problems of time travel. Karin, a genetic trouble shooter from the future, goes back into the past to prevent Junta from becoming the first mega-playboy and siring a hundred children. Each of the male children will also become mega-playboys and sire a hundred children - eventually causing the world to become overpopulated. Unfortunately, when she hits him with a DNA bullet to make him normal, it turns out that she has instead changed Junta, a boy who cannot even be near a scantaly clad women without vomiting, to instead turn into the mega-playboy (a person who can seduce any women). Now she must somehow find a way to undo the genetic alteration before he has sex as the mega-playboy and his DNA becomes stabilized in the mega-playboy state forever. To make matters worse (in typical anime fashion), she has fallen in love with him.

        Its even more enjoyable when you actually do gene therapy research (like me ^_^). Unfortunately, it should take at least another 100 years of research before anything even a fraction of what is shown in the series becomes possible. Oh, hum.
