Earth is no longer ruled by humans. Over a hundred alien species walk the planet—some conquerors, some slavers, some scientists, leaving humanity broken, experimented on, and scattered.

In the middle are Aki and Shiki, two kids fighting to stay alive in a world built to crush them. Survival isn’t enough.
