Among the orcs, a race whose mind is filled with nothing but lust and food, a certain individual was born.

He uses rational thinking to control his sexual urges, thanks to a unique outlook on life.

One day, he found a certain book mixed in with the belongings of a human his companions had abducted.

The book described a gentleman’s way of life: showing kindness to women and children, and never forgiving evil deeds. After reading this book, he decides to become a gentleman, though this particular book speaks of how to become both a respectable, and lecherous, gentleman:

A gentleman-by-day helps those in need. He is soft-spoken and has a gentle heart.

However, he mistakes the writings of immorality and salacious play as the way to becoming a gentleman-by-night.

With both of these as guides, he proceeds to make the women of various races slaves to his libido.
