Zanma Bakki Another Queen

Modified humans known as fiends are created with the purpose of crossbreeding to make a new race.
To fulfill their desires, both they and Queen battle nightly in Hachimiya City.
Among this, a new powerful girl with a similarly modified body arrives to hunt the fiends. Her name: Another.
What more, Queen gets captured by this girl's sponsor, Gold Bag Pharmaceutical, and is confined in an underground facility.

Immortal bodies, powerful pheromones, tons of cum, cruel rape that takes their bodies to the limit.
These girls continue the fight against the fiends for the sake of the next generation.
