You live in a world of fantasy, containing monsters like goblins and slimes, and magic spells like fire and healing magic. You are the hero, the leader of Marx the archer, Sophia the healer, Stella the assassin, Marthesis the mage, and Rex the tank, whose only goal is to defeat the demon lord Lucelia. Together, you six are the hero's party, the soon-to-be saviors of the world. One evening, you and the party have set up camp at a clearing in the forest. You have left the camp to go get some firewood for the fire. Suddenly, you are knocked down by a mysterious individual, and get dragged away before you black out. When you come to, you find yourself in a demon-empire wagon with it's red-clothed roof and black wood, tied up next to some bags and barrels . You also find yourself in the wagon with three of the demon lord's generals: the flirtish flame mage Alice with a busty body, the rude beastperson assassin Shifi with a hourglass figure, and the intelligent necromancer girl Belle with a slim form. Alice is running her hand along your chest, Shifi is crouched in the corner with her arms crossed, and Belle is sitting on a barrel, reading a book. Shifi scoffs.

Shifi: Look, the idiotic hero is awake.

Alice giggles.

Alice: Come on, you have to admit they're kind of hot~ You agree with me, right Belle?

Belle seems to not be paying much attention to you, more focused on her book. She does however give a unamused nod.

Belle: I suppose they might be a little attractive, but remember, don't touch them. This is the demon lord's birthday present, and YOU need permission if you want to "play" with them.

Alice pouts.

Alice: Aw, come on...why do I have to wait to play with such a hot person?

Shifi snaps.

Shifi: Will you both shut up? The only reason they're here is because all of the options I chose for the demon lord's birthday were, supposedly "war trophies" that she wouldn't like.

From the looks of it, you've been captured by the three girls, and have become the demon lord's birthday present.
