In the 1940's, the Nazi's were preforming multiple experiments on people, about different things, trying to make humans perfect.
They were doing one project; to create immortality. They called this giving people the power
of God. They were not allowed to preform these experiments in Germany; the Germans were not allowed to know about the experiments in any way, shape, or form.
So, the Nazi doctors went to an orphanage in Shimane, Japan, claiming that the orphans had "nothing more to live for."
Their theory was that there was a universal killswitch in every living being, which tells the person to die. They figured that this was the reason that a fly can only live a week, whereas other insects can live longer. They thought it's somewhere in the brain, and your subconscious tells your body to die.
The caretakers agreed, and the doctors started getting models of their brains. They had a human one from a caretaker, and one from an orphan girl. They discovered that the killswitch was in the cerrebelum
They started their experiments, and started with the tallest girl at the orphanage. They were too rough with the procedure, so she died. They started being less rough, and in the beginning of May, 1943, they had a success. They operated on a six year old girl, and she survivedd the operation.
However, whem she slept; she was clinically dead.
The Nazi doctors brought in Russian doctors from Projekt Venom: which was basically zombification.
They managed to revive the girl each time she died, and the experiments continued.
The Russians only agreed if they could use the girl for their research, sothey tried to create a prosthetic arm. However, they got too scared (of what, we don't know), and left before they could continue, leaving the girl without an arm.
After the doctors brought in the Russian doctors, who had succeeded in reviving the girl so that she was stable, they continued the experiments. They tried different entries although the patients survived, they were still unsuccessful; One boy was left mentally retarted and without a forehead, a girl was left with a mangled lower jaw, and no tongue after they tried an entry through the lower jaw, and a last girl was half deaf after entry through side of the head.
There was a young eight year old girl who felt the operations weren't right. She broke into the labs, and tore up research and broke the glassware. The doctors had her beheaded with a blunt baoynet, and she was just thrown into the woods in the back. She had red hair and heterochromic eyes, brown and blue.
Eventually, all but four of the doctors left, having shown signs of insanity. There were 10 survivers of the surgery, both caretakers and orphans. The head caretaker asked the doctors if they would play a game, Kagome Kagome (see the survivors personalities), and three of the four agreed. The last was horrified, and fled from the orphanage.
The three scientists never returned from the orphanage, although no one is sure what happened.
