俺だけの終末シェルター

Betrayed and devoured by his first love, Shinkai Sho is reborn with a godlike storage ability and only ten days left before the world freezes over. He sells off his fortune, spends like a king, and stockpiles billions in supplies to forge an unbreakable shelter. While the world dances under the first snow, he ascends as the one true ruler. This time, the hunter and the prey will trade places forever.
