エストレア・マニュー・パイクォーツ

The princess who rules Piequartz. As one might expect from the Big Breast Tribe’s princess, her boobs are huge. 

She’s smart, beautiful, charismatic, and young, yet said to be the finest ruler in generations. 
She has a gentle smile and is popular among her people. 
But that gentle smile is but a facade for the outside world; in reality, she’s a sadist who loves toying with people. 

Even as a princess, she fights on the front lines, using her beloved whip to bully people until they break. 
Those soldiers who experience it are traumatized enough to never appear on the battlefield again. 

At first glance she seems perfect, but she has a big complex about her chest.
