Now there are only two classifications of humans in the world, and they are based on "functional classification"! Humans only have 2 functions! One kind of people are treated as "guinea pigs" by hospitals and constantly receive new drugs and treatments! The other type of people are used as cannon fodder on the battlefield, used to experiment with the lethality and power of new weapons! We are all one of these two types of people! What's more fortunate is that when it's your turn, you'll already be dead! Then you won't have the chance to be a "guinea pig" and "cannon fodder"!

現在全世界的人類只有兩種分類，而且是根據「功能性分類」！人類只有2種功能！1種人就是被醫院當成「小白鼠」，不斷接受新的藥物與治療方法！另一類人就是在戰場上當炮灰，被用來實驗新武器的殺傷力和武器的威力！我們都是這2種人的其中一種！比較幸運的是：輪到你的時候，你已經早死！那你就不會有機會當「小白鼠」和「炮灰」！
