This armor was designed and modified by Mizuki for the purpose of infiltrating tactical local networks on the frontline. Based on a heavy-duty armor suit capable of withstanding high loads and voltages, it has been customized with specialized equipment including a peripheral vision system, high-voltage capacitors, and electronic armaments.

During full neural immersion (jack-in) where Mizuki is rendered completely defenseless, control of the suit is delegated to the onboard AI unit, Little, which operates the armor autonomously. While its combat functionality is intended to be restricted strictly to self-defense, Little exhibits a somewhat inexplicably aggressive disposition.
