An encyclopedia of 'monster girls' who are beautiful, but some of whom have non-human, strange-looking bodies.
The monster girls are extremely lustful and are always looking for a partner.

If you are still not afraid of them and want to know more about them, please enter the world of 'Monster Girl Encyclopedia'.
