Haramasekai The Movie ~Mainichi ga Kozukuri Youbi~

My name is Yamato. I am a rare person.
That is to say, I am one of the 0.01% of the population that is "male".

What happened, you ask? The curse of god or the work of devils, nobody knows. But the whole world's male birth rate took a nosedive.
Now the ratio of men to women is 1:10721!
This unprecedented crisis of humanity requires new legislation.

Today, the sex law goes into effect:

1) Adult male masturbation is forbidden.
2) Contraceptives are forbidden.
3) No adult female shall refuse the sexual advance of an adult male.
4) Refusal of sexual advances by any female will invoke the Child Conception Countermeasure Law.
5) Lapsed activity in procreation by any male will invoke the Child Conception Countermeasure Law.

Welcome to the new world order, where f*cking is the most important thing.
Happy Birth Day every single day, to all fornicating men and women!

The ADV story focuses on a male protagonist.
His partners are two sisters, childhood friend elder and her tsundere imouto.
What a lovely pair of girls to spend this government-ordained sex life!
