Blurb
Thousands of years ago, the Earth was under the ownership of Pink Diamond, one of the matriarchs of a great otherworldly race known as Gems. Pink Diamond wished to colonize the planet, taking every bit of its resources until there was nothing left. However, one of her subjects, a Rose Quartz, had come to admire the beauty and worth of the planet, and the many life forms that called it home. Desperate to save the Earth from destruction, Rose rebelled against Homeworld, and a long war commenced. Many Gems joined Rose in her cause, also seeing the value of the Earth. After a thousand years of bloodshed, the rebel Gems were successful, and the Earth was finally free of the Diamonds' tyranny.

Thousands of years after that, strange, flesh-craving humanoid giants known as Titans appeared, and began ravaging the Earth, driving humanity and the Earth-residing Gems to near extinction. The few who remained sheltered themselves behind a set of three large concentric walls, where they finally received long-sought peace.

But a century after humanity and Gemkind fled to the sanctuary of the walls, the outermost wall was breached by a Colossal Titan, and the destruction of the Titans resumed once more...

Summary
Shingeki no KyoGem closely follows the original canon of Attack on Titan, but has Gems present in its lore. It follows Bloodstone, a former Crystal Gem who works with the Survey Corps.
