The Complete Story:

(or at least the parts I thought were important...)


Key is a robot who lives in the little village of Mamoida. Her Grandfather, Mima Tikiko built her, and as she grew up, he continued to change her body to match her age. Being a robot, she was teased by her classmates, and had only one friend, Sakura, who eventually left Key and the village.

Key doesn't need to eat or sleep, other then when she blacks out, but when she wakes up, her grandfather is always there, telling her that she had a malfunction and that he fixed the problem.

One day, when Key came back from school, she found out that her Grandfather had died. She was told that he had fallen down a hill, totally by accident.

Her grandfather had left Key a tape recording, telling her that it was possible for her to become human. All she has to do is to make 30 thousand friends, and that she should do it as soon as possible, before she malfunctions again, and goes into a sleep in which she never can wake up from.

Realizing that it would be impossible to make thirty thousand friends in her tiny home village, she goes to Tokyo.

There, she met many people, and met up with her old friend Sakura. After telling Sakura about her mission, Sakura said that she would help her her, and that a good way to make many friends is to become a star, like the singer Miho, Key's idol.

What they don't know is that Miho isn't really the person everyone thinks that she is. She had been replaced by a PPOR robot which she controls in the backroom, but controlling such a machine is strenuous on the human body, and so Miho is actually very weak and about to die. However, Ajo, the head of the company she works for, insists that she continues with her work. She is more like a prisoner in the company.

PPOR robots work with a special gel, which is like a life-force. This life force was extracted from people, leaving the person's body like an empty shell which eventually dies. Ajo had been kidnapping many people to extract their gel, leaving the hollow bodies to die.

Key seems to have magical powers, and exhibits human emotions when she does. The cult priest "Prince Snake Eye" is convinced that she has God-given powers.

The PPOR robots used by Ajo seem to be affected by Key's presence. No one knows why, but whenever she is near, the machines all malfunctions, harming whoever is controlling them in the process.

But who is key really?

Ajo's company was desperately trying to find a replacement for Miho, who was extremely frail and almost ready to die. Sakura was spotted by a recruiter, and was kidnapped. But Ajo decided not to use her as Miho's replacement, and extracted 20 units of gel from her to use for his robots, leaving Sakura to die. Key and moved by the loss of her friend.

Tomoyo and Tataki figured out that Key had an abnormally large amount of life-force gel within her, since she never used any of it up as a robot. Her human/emotional form was sleeping within her, and they tried to wake her up so that she could use the large amount of gel and destroy all the PPOR robots.

Sakura's death almost succeeded in waking the human side of Key. She was upset by her friends death and cried.

Tomoyo and Tataki plotted a plan where she would upstage Miho at her final concert. They managed to get the crowd of more than thirty thousand people to cheer for Key,and she woke up.

But she didn't want to be awake. She cried. Being human is so painful. So much loss and pain... so she reverted back to being a robot. In a dream, she saw images of her mother, telling her that she needs to be human in a world when so many people needed her.

So she went back. By that time Ajo had started extracting the life force from the whole audience, and everyone was dying.

Key opened her mouth and started singing her lullaby-song. Life-force oozed out of her and covered the audience, replenished their souls,and restored them back to life.

Key found Sakura's life-force gel in container, and was happy to be reunited with Sakura, even though her friend was really dead.

The sun rose and the people in the audience started to wake up. They realised that Key had saved them, and cheered for her.

Key smiled and waved at them. She had become human.
