Japanese name:

キース アニアン

Raised in a test tube for the first 14 years of his life, Keith does not remember anything before his non-existent adulthood exam. Labelled as an "android" by Seki Ray Shiroe, he is known for his exceptional mind and elite skills on-board educational station E-1077, on which he befriended Sam. His continued outstanding performance earns him a rapid rise in ranks, and he eventually comes to lead all of Humanity at the young age of thirty.
Interestingly, despite being pitted against Jomy and the Mu several times throughout the series, Keith's portrayal is similar to that of an anti-hero and somewhat of a second protagonist, rather than a "villain". His connections and experiences with the Mu ultimately lead him to betray Grandmother, and the SD system itself.
In the DVD-only Epilogue episode of the anime, it is shown that in an unknown future Keith is reincarnated and reunited with Jomy on the successfully-terraformed Earth.
