The MC Is The Undying Queen Of This Immoral World

"Strip," the Colonel said.
Marianne Silvers was called to the tent of the Colonel just moments before the actual war.
Maria trusted the army, but she was wrong and found herself forced to spread her legs.
Her answer? "No."
She'd had enough.
She'd had enough and she chose her fate.
She took the gun, she took the shot.
But it was all for naught as she was the one who fell on the ground, bleeding.
Before she was murdered, she was summoned. To another world!
She was summoned by the Undead queen- and now, she has to fight heroes from another world to free demons from the terror of Men.
