Rad

A Rad (ラッド) is a small Trion Soldier specializing in reconnaissance and spying, its very similar to a remodeling machine that installs gate-outbreak devices. They usually hide themselves inside another Soldier, and after it is destroyed, the Rad conceals itself underground.

When there are no more people in its surroundings, it starts to move around in places with lots of people in the vicinity and it enters the gate starting-setup mode. To open the gate it gathers Trion little-by-little from the people who walk close to it. They are usually found in large numbers nearing the thousands.
