Inspired by the Metal Device, Caroline developed a similar, prototypical suit using weapons from the Units. Unlike the Regular Army's high-tech suits, the Unit Suit does not connect to the wearer's nervous system and thus anyone can wear it. Unfortunately, the Unit Suit's heavy material and artilleries requires the wearer to have extraordinary strength and stamina to operate. Caroline also built the Unit Suit to fit her small frame. From the Ptolemaic Army's crew, only Josette has the ability and frame to pilot it.
The Unit Suit has two weapons. The Unit Suit's electric claw is used to punch those up close. The claw can be charged up and released by slamming it to the ground and producing a wide lighting bolt per strike. The Gatling gun fires lasers. The Unit Suit also has high mobility as Josette can jump at great heights and attack at rapid speed.
- Normal Unit Suit: The original. It can regenerate health and is immune to stun. When hit by a stun-based attack, Josette charges up her claw, slams it down and generates multiple lighting bolts in front of her.
- Special Unit Suit: Colored green, the suit has been customized to take advantage of its mobility. It is able to counterattack.
