In a world of nothingness, nothing is a thing. As advanced as it had become, the selfish nobles and royalties took over every rights and power against the humanity, creating a new-world armies of bought-scientists and doctors. Commoners are just living-machinery; men forced as slave, women used as toys. Children? What children? They're no longer recognized as a part of beings, they're merely skins packaging organs and blood, for the use of the living adults. To keep the adults living forever, for them to be immortal. How? Using their latest technology; scythe-like extractor, known as the Soul Reaper, penetrating it through ones body extractors ones soul but preserves the organs and blood for as long as wished. Implanting and replacing are now known as merely 'cleansing ones body'.
