I Build NIKKEs in the Apocalypse

I had just transmigrated, and there were only seven days left before the apocalypse. A nuclear bomb was about to wipe everything out from the start?

What’s there to panic about? The System awakened and gave me an SR-rank NIKKE, Rapi, from the start! While everyone else is fighting tooth and nail over a bottle of water, I’m already preparing to build the apocalypse’s strongest fortress with my gorgeous, badass NIKKE wives!

Outside the bunker lie nuclear winter and man-eating monsters. Inside is my own apocalypse paradise, filled with armed beauties who obey my every command!

“Commander, what’s our next mission?”

“Don’t rush. Come take a bath with me first.”
