Plot

Junta Momonari is a high school student with a very unusual problem. Whenever he becomes sexually
aroused by a woman, his "female allergy" kicks in, causing him to throw up. One day, Junta is confronted
by a girl in strange clothing who claims to be from the future. The girl, called Karin Aoi, tells him about
how the world has become terribly overpopulated in her time, to the point where having more than one
child is a crime punishable by death. At the root of the problem is a family of "Mega-Playboys": people
with sexual charisma and impulses that lead each of them to have 100 children that carry the Mega-
Playboy DNA, causing them and all their descendants to each have 100 children as well. All this started
with a single Mega-Playboy, whom Karin has travelled back into the past to deal with. Karin reveals to
Junta that she is a "DNA Operator". Her job is to make alterations in people's DNA that will change their
nature for the greater good of society. She intends to shoot the original Mega-Playboy with a DCM ("DNA
Control Medicine") bullet that will alter his DNA in order to relieve him of his mega-playboy qualities,
thus preventing the overpopulation problem from ever happening. She can then return to the future to
receive the reward that will allow her to finally get the "nice husband, cute pet, and sweet, sweet home"
she yearns for. She confirms Junta's identity, then, to his shock, promptly shoots him.

Junta, the boy who could not look at a naked woman without throwing up, was destined to become the
original Mega-Playboy later in his life. Escaping back to her time machine, Karin arrives to a message
from her boss in the future. Her hopes for a commendation on a job well done are dashed when her
rather upset employer points out that the DCM bullet she was supposed to use on the Mega-Playboy
was left behind in the future. By shooting Junta with the wrong DCM bullet—one which Karin planned on
using to create an ideal husband—rather than eliminating the Mega-Playboy, Karin actually created him.
Now unable to return to the future until she sets things right, Karin decides to improvise by making Junta
get together with the only girl who does not give him an allergic reaction: his childhood friend Ami
Kurimoto, for whom he does not feel any romantic affection, since he sees her more as a sister.
Characters

Junta Momonari (桃生 純太, Momonari Junta)

Voiced by: Keiichi Nanba (Japanese); Liam O'Brien (English)

A high school boy with a peculiar allergy to girls: he vomits when sexually aroused. He gains the ability to

Voiced by: Miina Tominaga (Japanese); Jessica Calvello (English)

A sixteen-year-old DNA Operator from the overcrowded future, sent back in time in order to prevent the
advent of the Mega-Playboy using DCM, however she brings back the wrong bullet from the future
which accelerates Junta in becoming the Mega-Playboy. All she wants out of life is a nice husband, a cute
pet, and a sweet home, but when she met Junta, she falls in love with him–at first because of his Mega-
Playboy powers, and finally because of him as a person.
