Eleven years ago they were once a happy family of five. The father was a chemist who worked from dawn to dusk but always seemed to find time for his family. The mother was a stay at home mom who took care of their three children. Their life was happy, never getting too rich though never too poor. They were the picture of a perfect family. But it all changed on one warm summer day...

The eldest son of only ten at the time and his mother had gone out for some groceries. The family waited for hours on a task which would usually only take fifteen minutes. The husband came back at dusk and his children were still alone and he panicked and called the police. They knew nothing of it nor could they find a shred of evidence about them.

The man fell into depression and slacked off at work as he thought about his wife constantly. He then looked over his remaining children with care and tried to get them to the safest extent as he could. He eventually decided to get remarried and married a blonde woman with a daughter around the same age as the boy would be. He thought she could be the same as the brother they had lost in the disappearance.

It all changed one summer day around when he had disappeared. A man appeared at the door and smiled upon the now teens. It was the brother they had lost many years ago but he was not their for a visit. He was there to protect the two so that he may protect the world from destruction...

-------------------------------------------------------------------------------------------------------------------

What happened in reality was, on that day when the mother and her son were out they got into the cross fires of a fight between an organization called the Silver Beasts who fight for the protection of the world and the Cathulists, who believe in death and destruction as a way of life and nirvana.

The boy and his mother were both caught up and the mother killed. In order to keep them a secret the Silver Specialists stole the child and hid the mess accordingly. The boy trained and became a master soldier and eventually the commander of Alpha squad, the first troop.

The Cathulists have found a way to destroy the world, by capturing a chemist who has made a virus able to kill someone in only a few minutes and all that would need to be was breathed in by the target. It was the perfect plan, however it was discovered that the codes were hidden away in the microchips the man gave to his remaining children.

Alpha squad was sent in to protect the girls and the boy was told who they were and how they related to him. He didn't truly care that they were his siblings, he would treat them just the same as any objective. But, he was told to be good and keep them happy and content.

Who will win and who will fall ?....
