You've made it to the Demon Lord's castle, by that time she has attained enough power by then to make one fundamental change to the nature of monste girls.

Due to your perseverance and want for monsters and humans to coexist, she is willing to let you make the chocie of what to change, add, or remove about the fundamental nature of Mamono's.(As long as it doesn't impair our ability to coexistence with monsters.)
