Amid the ruins of a nuclear blast, a wasteland mercenary is reborn in another world, his veins coursing with the blood of giants. Once more, he sets foot on the mercenary’s path—but this time, he is not alone. By his side is an endearingly soft and nimble cat-girl scout, her agility and cunning making her his most reliable ally. A gentle and naïve mushroom girl silently watches over him, wrapping him in a quiet, protective embrace. And a proud yet romantic swan-blade maiden wields her sword and shield, fending off every hidden blade that dares to strike. His days are not without warmth and romance. The fiery proprietress of the mercenary tavern prepares him a lovingly crafted breakfast each morning. A seductive yet brilliant female mentor shares candlelit dinners with him in intimate conversation. The iron-fisted yet tender Empress of the Steelblood Empire lends him her unwavering support. And the fearless pirate queen, ever the wanderer of the high seas, sets sail for him, braving the endless tides. Yet when these captivating women gather in one place, their rivalry ignites like a battlefield aflame. The legendary mercenary soon realizes he has fallen into a war far more treacherous than any he has faced before. As tensions rise and passions clash, he can do little but sigh in exasperation, wondering how to quell this smoke-free war before it consumes him whole.
