In a post-apocalyptic world ravaged by interdimensional horrors known as Viles, salvation comes from women who bond with mystical relics called Crimson Cores, gaining the power to fight back. Men? They’re non-combatants—at best, support staff. At worst? Dead weight.

That is… until Ren Takahashi, a seemingly average guy, stumbles into a dying warrior and accidentally forms a forbidden Crimson Pact—transforming into her living weapon.

Now bonded to the beautiful yet feared Kaela Voss, a disgraced ex-commander known as the “Demon Queen,” Ren finds himself thrust into a matriarchal military structure where men are property and rewards come in dangerously tempting forms.

But Ren isn’t just any Pact partner. His unique soul connection unlocks powers that shouldn’t exist. As enemies grow fiercer and politics turn deadly, Kaela and Ren must fight to prove themselves—on the battlefield and in the bedroom.

Power. Passion. Punishment.
Together, they might just become the weapon the world needs.

If the heat doesn’t kill them first.
