This is neither a reborn story nor an invincible protagonist story. The protagonist isn’t a self-sacrificing saint, the villains aren’t made stupid, and the book has no contrived scenes of characters throwing their lives away, so read with confidence.
The world is trapped by rules, and random disasters strike every week.
Tsunamis, meteorites that incinerate cities, city-destroying storms, bitterly cold winters, and one disaster after another take turns wreaking havoc.
While everyone outside struggles to survive, I’ve stocked my little building with supplies and live in peace, holding on to the stability that is mine alone through each cycle of natural disasters.
