Chris Ryall and Sam Kieth will collaborate on the four-issue miniseries.
"To combat the catastrophic death of a decaying Japan, survivors create genetically-engineered supertrees - wooden leviathans capable of supporting entire cities suspended above the radioactive wastes below," said IDW.
"Travelling via jetpacks to stay above the toxic air below, the survivors must also band together against the Hollows, irradiated husks whose humanity has been supplanted by an unquenchable desire to consume human energy."
IDW's chief creative officer and editor-in-chief Ryall is best known for his work on Zombies Vs. Robots.
Kieth is the creator of cult comics series The Maxx.
"The Hollows began as a more straightforward tale until Sam and I remembered that neither of us really tell straightforward tales," said Ryall.
"So the desolate setting for the story is really just the backdrop for a more personal tale of love, loss, redemption, faith, flight, and past versus future, all wrapped up and bound to the archaic flying suit of our protagonist, a beleaguered scientist/explorer named Kobayashi who ventures down from his city-state and finds something entirely unexpected."
The Hollows #1 will debut on December 19.
