[Gender Change, 1v1, Pure Romance]
After the Demon King Moli'an is soundly defeated by the female Hero, he has no choice but to use the one-time temporal rewind skill he can only use once in his life, fleeing back to when the Hero had just set out on her journey.
The price: the proof that he was a man...
All right, so I'm a Demon Queen now. I'm only missing one part, and I don't care! This time, I, Moli'an... Molliana, won't be naive and arrogant. I'll nip the Hero in the bud from the very start!
"Big Sis Hero, let me join your party!"
So says Molliana, disguised as a sweet, adorable rookie priest.
Heh heh. With the Demon King himself hiding in the Hero's party and secretly removing every danger along the way, the Hero won't be able to level up. Conquering her should be just around the corner!
Wait, what are you doing!? I'm the Demon King. Don't turn me into a fluffy ball of yarn!
Damn it, how did I not realize in my last life that the Hero was a lesbian!? Why are you being so rough!? I, Molliana, will never submit to you!?
