From the sterile walls of the White Room to the chaotic depths of the Ark. Kiyotaka Ayanokoji never expected to wake up in a world on the brink of extinction. Yet, as he opens his eyes in the wreckage of a transport, he isn't confused. He recognizes the Raptures. He recognizes the gun in his hand. And most importantly, he recognizes the artificial girl saving his life. Thanks to the idle ramblings of a former classmate named Sotomura, Kiyotaka knows this world. He knows the "Goddess of Victory: NIKKE." He knows the tragedies awaiting Marian, Rapi, and the others. He knows the corrupt politics of the Central Government. But Kiyotaka is not the Commander from the story. He is the Masterpiece of the White Room. Viewing the war against the Raptures not as a crusade, but as a complex chessboard, Kiyotaka decides to pursue a variable that the original story lacked: A true happy ending. With absolute knowledge of future events and an intellect bred for supremacy, he will build the ultimate Outpost. He will turn weapons into loyal lovers. He will rewrite the timeline. This is not a story of survival. It is a story of optimization. [Crossover: Cote x NIKKE] [Harem] [Slow Burn] [Explicit Content/R-18] [Smart Protagonist]

"Will the 'Ending' remain the same?" "Can I give them the 'Happy Ending' they truly deserve?" "Can I prevent the 'Tragic Tragedy' that will befall them?" "Can I... change their 'Fate'?" _______________________________________________ Kelvin Fujiwara is a HIKIKOMORI who shut himself away after losing his parents and younger sister in a tragic accident when he was just 15. Following his family's death, Kelvin became a reserved and cold person, showing little concern for the world outside his control, but he does care about what he can manage. He rarely smiles since that tragedy, and his life has only gotten worse since then. At 25, ten years after the incident, Kelvin has faced a lot of pain, sadness, and suffering. He's been abandoned by family, betrayed by friends, left by his girlfriend, dropped out of college, frequently lost jobs, and even faced bullying and harassment. Despite all this, Kelvin tries to live well, hitting the gym regularly, learning new things, eating healthy, and taking care of himself, especially his appearance. His only downside is that he loves to stay up late while sipping coffee. There was even a time he stayed awake for three days just to finish the Call of Duty Modern Warfare series. But one night, right after finishing Honkai Impact 3rd part 1, Kelvin experiences an intense headache, and when he wakes up, he finds himself in an unexpected place. He's been reincarnated into the game he just completed.
