DNA² OVA

In a future where overpopulation is a critical concern, a unique solution has emerged: genetic manipulation to reduce birth rates. Enter Karin Aoi, a "DNA Operator" from this future, tasked with a seemingly simple mission: prevent a man named Junta Momonari from becoming the Mega-Playboy, a figure whose genes would lead to an uncontrollable population boom. Her method? Alter his DNA to make him utterly undesirable to women. However, Karin's carefully laid plans quickly go awry, and instead of neutering his appeal, she accidentally amplifies it. Now, Junta finds himself inexplicably irresistible, much to his own confusion and the escalating chaos that ensues. As Karin desperately tries to correct her mistake, she uncovers a peculiar twist – Junta's intense allergic reaction to potential love interests, a condition that might just be the key to averting the future and its impending romantic catastrophe.
