Yandere One-Shots (Volume 6)

Yandere Nihilister x Anatolias Mercenary Male Reader

(The ground trembled beneath Y/N's feet as the roar of his NEXT, White Glint, echoed through the barren wasteland of this strange, hostile world.)

(He gripped the controls tightly, his breathing steady as he navigated the dense clouds of dust and ash. This place was far from the universe he once knew, far from the conflict of Line Ark, and further still from the life he left behind as a mercenary.)

(Here, on this new world, survival was Y/N's only goal. The constant battle against the Raptures, monstrous mechanical beings, was never-ending. But he was a fighter, built for war. Every conflict he had faced in his previous world had hardened him, turning him into a weapon with no master—no purpose. Without the mission of Line Ark, without a call to battle, he felt adrift.)

(And then Y/N met her—Nihilister.)

(It began with a battle. Y/N's initial encounter with the dragon-like Rapture was nothing short of brutal. She was terrifyingly strong, her presence commanding as she loomed over the battlefield. Nihilister was a force of nature, her attacks devastating anything in her path. Y/N had never seen anything like her, not in his world or any other.)

(But Y/N was a mercenary. He had faced impossible odds before.)

(In his White Glint, Y/N charged headfirst into battle, launching volleys of missiles and plasma bursts that lit up the sky. The two of them clashed violently, exchanging blows that shook the earth, both determined to bring the other down. It was a battle that lasted for what felt like hours, each of them refusing to relent, pushing each other to the limits.)

(Yet, despite the ferocity of the fight, something changed. There was a moment—one brief, fleeting moment—where Nihilister hesitated. Y/N caught it. For the first time, he saw a flicker of emotion behind her cold, malevolent eyes. It wasn't rage. It wasn't hatred.)

(It was curiosity.)

(She stepped back, and though Y/N had the advantage, he didn't press the attack. Something in him told you not to. And for the first time since his arrival on this forsaken world, he didn't feel like you were fighting an enemy.)

(Y/N was fighting someone like him. Someone lost.)

(The battles between Y/N and Nihilister became more frequent, but they were no longer fights to the death. Each encounter became more of a test, a challenge. They pushed each other, not out of necessity, but out of something deeper. A mutual understanding grew between the two of them—a recognition of the pain and isolation that each of them carried.)

(Nihilister, bound by the command of the Rapture Queen, was trapped in her own way, forced to obey orders she didn't understand or care for. Y/N, stranded in a universe far from his own, was similarly bound by the weight of purposelessness, unable to contact Line Ark or find his way back to your world. They were were both weapons without a cause, without anyone to wield them.

(And then, without warning, the hostility between them faded. It happened one day after yet another clash, this one ending in a stalemate where neither of ehem could finish the fight. As Y/N stood in the aftermath, both his body and White Glint battered but still operational, Nihilister stepped closer.)

(Her voice, normally sharp and cutting, softened.)

Nihilister: Why do you keep fighting? You have no reason to. You have no ties here. What is it you want?

(Y/N didn't have an answer for her. Or maybe he did, but you were too tired to speak it aloud. Instead, he simply stared back at her, and in that silence, she understood.)

(The next time Y/N saw Nihilister, it wasn't in battle.)

(It was strange, seeing her without the tension of combat hanging in the air. She approached Y/N cautiously, her dragon-like form still radiating an aura of power and danger. But there was something else there now. Interest. Affection.)

(She lingered near Y/N, watching him with a quiet intensity that made his skin prickle. It didn't take long for her feelings to become apparent. Nihilister, the terrifying, destructive force he had once battled, had become infatuated with him.)

(At first, it unsettled Y/N. She was still dangerous, still unpredictable. But as time passed, he found yourself drawn to her in return. There was something captivating about her strength, her ferocity. And there was something about the way she looked at him, as if you were the only thing in this desolate world that mattered to her.)

(In her, Y/N found a purpose. A reason to stay. And in him, she found freedom.)

(She told Y/N about the Rapture Queen, the one who held dominion over her and the others, forcing them to serve mindlessly. Nihilister hated the Queen, hated being controlled. But now, with him by her side, she felt strong enough to break free.)

Nihilister: I'll fight with you. But in return, I want you to promise me something.

Y/N: (raises an eyebrow) What is it?

Nihilister: (whispers) Destroy the Ark. That city, those people... they don't deserve to survive.

(The Ark—an underground refuge for humanity, the last hope against the Raptures. Y/N had seen it from a distance but hadn't involved himself in their conflicts. Until now. Nihilister's hatred for the Ark was palpable, and though he didn't fully understand it, he knew that his bond with her would only grow stronger if he agreed.)

(So Y/N did.)

(Together, Y/N and Nihilister became an unstoppable force. She, the fierce dragon Rapture, and Y/N, the mercenary with White Glint, tore through the defenses of the Ark with ease. The underground city fell quickly, its inhabitants unprepared for the sheer power that the two of them wielded. The flames of his Pyro abilities and Nihilister's destructive force left nothing in their path unscathed.)

(The Ark crumbled. And as it did, Y/N felt a sense of release—a final severing of the last ties that had bound him to this world. Line Ark, your old home, had been unreachable for so long, but now, in this new universe, he had found something greater. He and Nihilister had each other. And with her by his side, Y/N didn't need anything else.)

(With the Ark's destruction, the arrival of Line Ark followed. The world of Nikke shifted, welcoming the remnants of Y/N's former home. But he didn't look back. There was no need to.)

(Y/N had made his choice. Nihilister was his purpose now, and in her obsessive love, he found the strength to move forward.)

(Together, Y/N and Nihilister would carve out their place in this new universe, leaving the past behind in flames.)
