Description

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

He is able to consciously control his lustful desire, through a unique rational mindset.

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 who helps those in need, who is soft-spoken with a gentle heart.

Immoral, salacious play, which he mistakes 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.
