Rebellion
One child out of the whole orphanage, did not approve of the scientists presence. In her acts of rebellion she stole paperwork and ripped it to shreds, broke glassware and wrecked surgery theaters. Despite her young age (8 years old) and size, she had a surprising capacity for destruction. It was noted in a journal that she was heterochromic as well (brown and blue eyes from left to right). The senior scientists despised her, but could not restrain her without arousing suspicion. Instead, they ordered the Nazi soldiers to take care of her.
She was brutally beheaded with a blunt bayonet, she was not buried, just left in the woods behind the orphanage. The soldiers told the caretakers that she had found a new family.
Numerous failures
The Nazi scientists attempted to play around with their successful experiment by trying different aspects to it, sadly, none of them worked. Here is a list of them:
Entry through the forehead. Performed on a 10 year old boy, skull was deformed and the boy had been virtually lobotomized by the end of it. However, he wasn't vegetative as a result, although he was mentally retarded due to the experiment.
Entry through the lower jaw. Performed on a 6 year old girl, the tongue and most of the flesh on the lower jaw was removed and could not be replaced. The subject's sinuses were also scrambled.
Entry through the side of the head, subject was reluctantly half deaf. It should also be noted that there was no anesthetic during this surgery and the screams were truly mortifying, as most journals read.
Despite the failure of these, the kill switches were still removed, and the subjects acted in much the same way as the first girl, expiring upon sleep.
However, they were reduced to a mere ten people, due to all the previous failures. This is including the caretakers, and they had performed surgery on all the children.
Kill switch reversal
The doctors began to formulate ideas that in a child, a kill switch isn't already activated, but in an adult a kill switch could be reversed using a chemical compound to eliminate the hormone produced and the kill switch then removed.
This was performed on all the caretakers and was, surprisingly, successful as they all survived.
Personalities gone Awry
During the experiments, scientists were told to watch over the successful children, and monitor their behavior. This part gets freaky.
"They appear normal at first, just like any of the other children, playing cheering, learning normally, but when separated from the others, they seem... off. They stroll carelessly around, with a blank smile on their face, their eyes looking straight at you. If approached from behind, their heads snap around with ungodly speed and for a moment, you can almost see an expression so vile on their face that it makes you want to cower. But then you realize they are just forming their dreamy smile again.
Another thing is that they follow us, but only when we are on our own. After finishing on my typewriter and heading to my room, I am often given a fright by one of the children standing several meters down the dark hallway, staring at me. When I go off to my room, she follows me, and I shut my door, jam a chair behind it, and then I sleep safely. It feels like they're ghosts at night time. And the funny thing is, I keep seeing one child with reddish hair. I keep asking who the child is the next morning, but the caretakers say they haven't had a child with reddish hair for a while**
They also seem to be playing a game a lot more than when we started. I haven't got much knowledge of Japanese, but it seems the game is named Circle You, Circle You*, as described by one of the translators. A group of children surround one child, who sits in the center, alone, they link arms and begin to move in a circular manner around the child, making scary faces at them and singing an eerie chant, you lose if you flinch.
