Sarai [Manga]

In the future, rampant genetic disorders wreak havoc on humankind.Teenagers turn into grotesque monsters when they hit 18, and growing old is no longer a luxury—and only one kind of warrior has the power to stop it! Sarai’s got it all. She’s a sexy new kind of “peace officer”-a guard maid who can kick butt, clean house, and bring justice to a bleak world. If humanity has one last hope to heal itself and return to normal, Sarai is the catalyst.
