In 1992, a secret North Korean research facility began an operation called Project BOAS (Bio Organic Assault Soldiers) to take over Asia but failed to succeed in 1995. In 1999, North Korea revealed the information of the Project BOAS outbreak to the world due to the failiure to stop it and put its neighbors in panic. In 2003, Asia was overrun by the monsters of Project BOAS and they were renamed Fallen because of the amount of lives they've claimed. In 2005, the United Nations created a plan to defeat the Fallen and decrease their numbers but only lost more soldiers to them. In 2012, the Fallen were spread out through the world and the amount humans in the world were decreased 42% and the Fallen were steadily increasing by 3% each year since 2004. In 2015, a young girl named Stella Clovers was chosen to be a test subject for Project SS (Super Soldier) and it was a success with one side effect, they could not recreate the material they used to create Project SS, making Stella the only super soldier in the AFA (Anti-Fallen Army). In 2017, Stella left the AFA to help survivors gather together and increase the chances of human survival.
