20 years ago, a monster outbreak changed the world. Billions of humans perished. Stronghold cities with advanced technology alone prospered, leaving the rest of humanity to fend for themselves in small remnants of “civilization.” 

In this cruel, new world, Reina Romane just wants to get through high school and live a normal life with her friends. But there is a dark conspiracy in the works: an organization that wishes to create a global utopia by wiping out the current world order. They will stop at nothing to achieve this, even erasing humanity. Reina must join forces with unlikely allies if her world is to have any chance of survival.
