Key: The Metal Idol

Tokiko Mima, nicknamed "Key," is a 17-year-old girl living in the Japanese countryside who, despite her human-like appearance, is a robot. When Key's grandfather Dr. Murao Mima passes away, he leaves her a dying message, telling her that she can become a real girl if she is able to make thirty thousand friends. Thus, Key moves from the quiet Mamio Valley to the busy streets of Tokyo, where she soon runs into her childhood friend Sakura Kuriyagawa. Key quickly becomes enamored with idol singer Miho Utsuse and wonders if becoming a singer will allow her to make the amount of friends needed for her to become human. But Miho carries a ominous secret: she is connected to Jinsaku Ajou, an old rival of Dr. Mima trying to make new a breakthrough in robotic weaponry. As Key works to become a real girl, Ajou sets a dangerous plan into action, and it turns out there's much more to Key than meets the eye.

Cyberchase

15 Seasons
CYBERCHASE takes kids on a wild ride through cyberspace where they are challenged to use the power of math in a classic good-vs-evil battle. When dastardly villain Hacker (played deliciously by Christopher Lloyd) launches a mad mission to conquer the virtual universe, Motherboard calls upon three Earth kids for help. They are Jackie, Matt and Inez--the heroes of CYBERCHASE--who travel from their real-world realm with wisecracking cyber-bird Digit (comic actor Gilbert Gottfried) to the colorful virtual vistas of cyberspace, where they vanquish the bad guys in an all-out battle of wits. Each episode takes the kids on a thrilling adventure driven by a different math concept--from tackling time in ancient Egyptian tombs, to cracking codes in creepy caves, or making sense of numbers in a fractured fairy tale world. In their quest, the heroes use minds, not muscles, to overcome obstacles and danger everywhere. Every episode of CYBERCHASE concludes with a "For Real" live action segment in which a young comic actor encounters a situation which reinforces the math concept explored in the animated storyline.
