Run=Dim

In the year 2052, decades after global warming resulted in the polar ice caps melting & flooding large parts of the Earth, Japan's military organization JESAS is the midst of a battle with the UN-supported Green Frontier over who will take command of expansion out into space. This battle is a literal one, too, with JESAS having to rely on young teenagers who possess potential with humanity's 6th sense, which they've called "AI", to pilot giant robots called RBs to take on Green Frontier, which has a yellow RB named Run=Dim as its trump card. One of these teens is a boy named Kazuto Moriguchi, but after being deemed expendable when an experimental weapon named the e4 is fired during a battle, he defects over to Green Frontier, even if it means having to fight those he had started consider to his friends.

Super sadly this is the only one of its kind
