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]
