“Good morning, ready for combat operation.”

AD 2172. A military raid, under the command of BAHRAM’s Commander Nohman, is carried out on Antilia, a space colony orbiting Jupiter. The objective of the raid is to retrieve 2 orbital frames from the colony. After watching his friends be taken captive and later crushed under a battle damaged LEV, a small boy named Leo Stenbuck runs for his life. He takes refuge in a hangar for orbital frames and accidentally falls into Jehuty, activating the frame.

After escaping the hangar, ADA patches trough a transmission from Elena Weinberg of the civilian transport vessel, Atlantis. She pleads with Leo to carry out the mission assigned to Jehuty and the frame’s designated pilot, Alan, who is missing in action. The mission is to deliver orbital frame Jehuty to Atlantis’ base on Mars, in preparation for battle.

Jehuty underwent a complete system overhaul before the events of Zone of the Enders. The most important addition to the frame was the advanced onboard battle computer, ADA. Due to the overhaul, Jehuty is left with minimal system capabilities.

Viola, runner of Type C Orbital Frame “Neith”, becomes a fierce rival to both Leo and Jehuty leading to several heated confrontations through-out the course of the game. Viola is part of the BAHRAM forces sent to retrieve Jehuty and the second orbital frame, Anubis.
