// 01 · INCOMING TRANSMISSION

Twelve-year-old Aku
dreams of space.

Arthur Keaton Underwood. A.K.U. for short. Inventor. Daydreamer.

Then the basement
starts beeping.

A taped-up box, addressed in heavy letters:
TO: AKU / OPEN IMMEDIATELY.

Inside: his missing
grandfather’s helmet.

It knows his name. It asks if he accepts the mission.

Destination:
Ibra.

One minute on Earth. Thirty on a planet under siege. And Grandpa is alive somewhere on it.

His hero is
the villain.
