Game Sekai de Mamono ni Tensei shiteshimatta Ore, Zense de Oshi datta Heroine wo Hirotteshimau

Upon awakening, the protagonist discovers he has been reincarnated into the world of a video game he once played in his previous life. However, there is a cruel twist to his new reality: rather than being reborn as a hero or adventurer, he now exists as a monster inherently hostile to humanity. Accepting his bizarre fate, he chooses to live a quiet, secluded existence far from human settlements to avoid conflict and detection. His peaceful isolation shatters when he stumbles upon an unconscious young woman collapsed near his dwelling. To his absolute astonishment, she is Noa, the very heroine he adored above all others during his past life. Unable to leave her behind, he takes Noa in and carefully nurses her back to health. Grateful for his protection, she gives him the name "Rei," sparking a profound sense of devotion within him. From that moment on, Rei resolves to follow and safeguard Noa as his ultimate idol for the rest of his days. As they journey together, he encounters familiar faces from the game's original storyline and quietly watches over Noa’s growth. Yet, the real Noa proves to be quite different from her fictional counterpart—she is unexpectedly clingy, harboring a remarkably intense and heavy affection for him. Together, this unlikely pair must navigate the challenges of their world, forging a unique bond between a former player turned monster and his beloved heroine.
