A world without... what?! That setting wasn't in the game manual!
You suddenly wandered into the world of an RPG. It's your favorite game, but the way everyone is looking at you is strange. It doesn't seem to be just a matter of your unfamiliar clothes.
(You didn't notice because gender wasn't explicitly displayed during the game.) It seems women went extinct about 300 years ago due to a plague.
And as a rare "girl," you possess mysterious powers. Touching you restores vitality. Being smiled at by you grants strength. Just smelling your scent relieves fatigue.
And... kissing you heals wounds? ...Seriously? No way!
The world, once a battle between the Hero and the Demon King, changes its face.
For the sake of the world? No, you guys have other motives, don't you?
Hero Cecil "The only girl in the world? She should be by the Hero's side. I'm the one who can protect her."
Demon King Belius "It is tradition for a princess to be kidnapped by the Demon King and become his bride! Become mine!"
Healer Luca "I worked so hard to polish my magic and win the Hero's heart, and a girl heals just by existing?! That's so unfair, damn it!"
I thought I'd finally get to see the precious, bittersweet moments of CeciLuca in person, but now Cecil is locked onto me!
I mean, go defeat the Demon King! That's what this game is about!
