Onna no Otoko Kenkyuusho

Ayae Matsudo (female, scientist) awoke with a jolt.
She'd dreamed that the world was nothing but men.
"This will the downfall of humankind!" she gasped.

Immediately she set to work on a boy-girl hybridization.

This beautiful genius, this inventive doctor Ayae,
would save the world from its own gender death.
She would create feminized men.
