Milia has inherited the title of hero! But it was actually supposed to go to the prince, Rick. Rick was executed for his perverted crimes, but his spirit lingers… and makes a contract with the Demon Lord so that he can possess Milia!

The protagonist, Milia, a warrior princess, questions why she must lose her virginity with a supporting character. She feels it’s part of her duty as a heroine due to the influence of a goddess in her head. Although she doesn’t fully comprehend the situation, she decides to focus on her adventure. During her journey, she defeats trolls in the village, searches for treasures in the academy, and faces horny situations. Despite wearing sturdy armor, she’s surprised to realize that she is now dressed in tight gym clothes.

I, Milia the Hero Princess, have finally overcome countless hardships and found the location of one of the “Three Sacred Treasures”! Wow, it’s finally starting to feel like a real hero’s adventure! Sure, I’ve been drenched in semen and ended up naked on the roadside, but hey—progress is progress! “Fight me in a sex battle!” Huh? What do you mean? Me, in a sex battle against a succubus? Why are there so many naked men around…? Well, I guess it’s not that weird after all. I do have a super lewd body, and I am a genius at making cocks feel good ♪ Alright then! Stick it in—my pussy, my ass, wherever you want! Go ahead and shoot all that semen right into me! Obeying the (fake) goddess’s (fake) orders, Milia happily covers herself in semen of her own free will. Next up… a sex battle against a dark-skinned, big-breasted succubus!? …Wait a sec. Isn’t this all kinda weird?
