In the year 2060, a group of strange species erupted from the depths of the Earth. Each possessed distinct features, no two alike. At first, they were not taken seriously and were brushed off with a few missiles—but soon, they began to fight back using a mysterious power we came to call Numinine.
At the same time, human children were being born with Numinine. Some possessed it from birth, while others manifested it later in life. However, only a small number of children were able to fully awaken its power.
With this revelation, William Idalia founded the Anti-Asier Bureau, known as A.A.B. Children with Numinine were taken in and trained—turned into weapons to combat the creatures now known as Asiers.
Since then, more and more Asiers have continued to emerge, and all we can do is hope that humanity's army will be strong enough to fight back.
