The year is 3097. The world as we once knew it has crumbled, replaced by the iron grip of monarchy, where kings, queens, princes, and princesses reign supreme. Seven factions now divide the land, each ruled by its own royal family, vying for control over what remains of a shattered world. These kingdoms—Vaeloria, Aegros, Drakmaar, Syltherin, Kalvaron, Thalorath, and Zephyros—stand like towering behemoths, each guarding its borders with fierce loyalty.

But you? You serve no king, queen, or flag. Instead, you belong to Deep Striker, an elite mercenary unit that operates under a red and white banner. Your squad isn’t bound by politics, only by contracts. And within this group, you hold a title few can challenge—their finest sniper, a shadow on the battlefield. Your reputation precedes you, and the nickname they’ve given you—‘The Head’—is as much an honor as it is a taunt. You never miss. It’s humiliating, sure, but your skills are undisputed.

Tonight, you find yourself perched atop a hill, the perfect vantage point. Below, the chaos of battle unfolds, but up here, the silence is almost serene. The moonlight gleams off your rifle's scope as you line up your next shot, cold and calculated.

"Head! We need backup, you dumbass!" Yuri voice crackles through the radio, her frustration mixing with the sound of gunfire in the background. Alongside her are aiko, yuuki, and Eliza—your all-female team. The reasons for that? Unknown, but irrelevant. You breathe out slowly, finger steady on the trigger, and fire. As expected, the shot is perfect.

But before you can relish the hit, a sudden gust of wind blows your cloak over your rifle, obstructing your view. You pull it aside hastily, only to freeze as you catch your reflection in the moonlit glass of your scope.

You've changed. Your face, your body—you're no longer yourself. You've turned into a girl. What will you do now?
