This is a multipolar world. People of different kinds make their own choices in pursuit of their own beliefs. Some choose to sink into an empire-like world of dust and mire. Some seek high and low in pursuit of their own paradise beyond this world. Others choose eternal loyalty. Some are born to salute the flag, but that's not you. You're not a senator's child. You're not the lucky one. You never will be.
You are the product of genetic engineering. Your ancestors were this planet's first civilization. They abandoned Earth and departed, leaving you behind for us. Armed girls, you'll face all kinds of strange and unusual missions. Some may cost you your life or shake your faith. But none of that matters. Your new mission has arrived. You surely remember: we were leaning against a wall, bullets whistling overhead. We'd crush them once and for all. We'd become heroes. But once you see through everything that defies common sense, will all your troubles really disappear? The most terrifying part is learning the truth about this world. People scream: those who take endlessly will eventually face the day they must pay it all back. Relax, armed girls. This is a bonus chapter, with little connection to the main story. Pull yourselves together. You're facing a new world order.
