Sarai

In the desolate future depicted in Sarai, catastrophic floods have completely submerged Japan, leaving behind a barren and lawless wasteland where societal order has all but collapsed. Compounding this devastation is a devastating genetic anomaly that plagues the surviving population: humans rarely live beyond their sixteenth year. Those who manage to surpass this grim biological threshold suffer a horrifying transformation, mutating into grotesque monsters. In this unforgiving landscape, survival demands extreme measures, and one of the few remaining sources of security comes from warrior maids—elite bodyguards available for hire who serve as fiercely devoted protectors bound to their clients' service. Among these formidable mercenaries are Sarai Kannagi and her partner, Flicker, who navigate the treacherous remnants of their ruined world together. As they take on contracts to defend those willing to pay for their protection, the duo faces an array of nightmarish threats born from this broken era. Their perilous journeys pit them against former humans twisted into towering rock creatures, savage arctic tribesmen, and other terrifying abominations that now roam the devastated earth. Through relentless combat and unwavering loyalty, Sarai and Flicker fight to carve out a fragile existence in a world defined by mutation, ruin, and despair.
