Original summary : "With incessant fighting studies and sexual training, every day is a challenge for a kunoichi in training.
And when the night fall, they are fated to fight life or death struggles against ennemy ninjas.
They must unleash a storm of bood and sperm with their erotic ninja skills, and defeat their opponents with their lustful body !
Day after day, they have to face the same challenges again and again, till they master the way of the Miroku kunoichi.

It's my first serious work since I decided to do a series with this concept, so expect a lot of different atmospheres (light-hearted, hard sex, or bloody)."
