In this world, everyone who has read knows that there was an extremely dark period in history, known as the Age of Greed. During that period, there was a large-scale base for microbial research and development using many underage boys and girls as petri dishes. Later, the base was inexplicably bombed, and no one inside was spared. This was a very curious event, but unfortunately no one knew the inside story.
