An 8ft realistic mecha animation "OBSOLETE" taken on by the exceptional talent
Gen Urobuchi and the up-and-coming CG animation studio BUEMON.

In 2014, aliens revealed themselves to request trade with humanity.
In exchange for limestone, they would provide
a consciousness-controlled general-use robot known as an "EXOFRAME".
Cheaper than an aircraft, tank, or firearm, and easy enough for anyone to operate,
the "EXOFRAME" spreads change throughout the world in the blink of an eye...

"This is being broadcast on all radio frequencies in five languages.
We do not wish to be involved in politics or cultural exchange. We wish only to trade.
For every 1,000 kilograms of limestone, we shall provide you
with one of our technological productions.
We shall not distinguish between nationality, ethnicity, ideology,
or any other discriminator.
We offer these terms of exchange impartially and equally to all of humanity."
