Disclaimer: I do not own DNA2, unfortunately. That honor goes to Masakazu Katsura. Unfortunately, the series is 13 years old by now and there's no chance in hell there's going to be another OVA or more episodes. And it's so obscure that I'm amazed that there's even one fanfic I can find. But I will try to raise awareness to this great and original anime the only way I can (at least without getting arrested).
Introduction: DNA3
It has been just three weeks since the Mega-Playboy incident, and already the United Nations government is complaining. As the Mega-Playboy now does not exist, neither do his descendants. By the time Junta Momonari had died, if he had turned into the Mega-Playboy, his living descendants would be greater than 1,000,000
But because of the actions of the Department of Time Control, 1,000,000 people suddenly found themselves wiped from existance. This might not have seemed a problem at first, as the world was already overpopulated, but. in the long run, it affected everyone on the planet...or at least the ones living in Japan.
As the Mega-Playboy now "never existed", everyone who was not directly involved in the incident had no knowledge that 1,000,000 people were now gone from the Earth, because they were never supposed to be there in the first place. However, to the Department of Time Control, this was a major problem, the world now looked different than before, the economy was lapsing, and the world was in war. The UN government was helpless...
Karin Aoi now has a new assignment. Not as a DNA operator, but as a "time cop". To find out why the world turned out so different after the destruction of the Mega-Playboy. The agency employing her is also different. No longer is it the Department of Time Control. No. The UN Secretary-General himself had authorized the expansion of the department. It was now the Department on Safeguarding Earth. Once again, Karin Aoi was to clad her purple and white armor, and travel through time.
100 Years in the Past
"Do you see that?" asked a bewildered Junta to his childhood friend, staring up at a fading star in the evening sky.
"Yes, Junta. I see it, it's a special star, and drink in all it's color before it's gone...forever...goodbye. Karin."
"Karin?"
"Nothing, Junta, let's go home."
