Steven Universe

Steven Universe is an animated American TV show about a young teenage half-human half-Gem hybrid named Steven Universe and his adventures with his three overseers Garnet, Amethyst, and Pearl, the three remaining members of the army known as the Crystal Gems. On his journeys, Steven learns about his Gem heritage and abilities through not only his guardians, but through accidental discoveries and even his enemies as well. He and the Crystal Gems live in Beach City, a small beach coast residency that's hardly a city inhabited by humans who don't find magical rock people strange in the slightest.
