Rei

レイ

The AI on board the SPT-LZ-00X Layzner possessed such advanced intelligence that it developed a distinct personality, which Eiji nicknamed "Rei". Although Rei exhibited feminine traits and the demeanor of a sweet child, she lacked any sense of morality. She typically advised destroying the cockpit of an enemy SPT—instantly killing its pilot—rather than disabling its limbs, as she believed this to be the most effective method of defeating an enemy. Frequently, she would take control of the Layzner herself to protect Eiji and the SPT from damage.
