A sudden catastrophe destroys peaceful days. A once wealthy young lady is framed by greedy relatives and stranded in a foreign land. In desperation, she gains a secret storage space and meets her long-silent guardian. They gather supplies, tame magical beasts, gather companions to build a safe home, rely on each other through troubled times, and finally find a peaceful new world.

Everyone loathes my princess-like arrogance, unaware I am the undisputed top powerhouse of the apocalypse. The noble lady acts lazy and laid-back in daily life, while unleashing hidden strength to wipe out savage monsters. She conquers doomsday survival perfectly by pretending to be weak to defeat the strong.
