Jacqli's Back Story in A.T 2

After the canonical ending of the first Ar tonelico, Mir (Jacqli), together with Jack, Krusche, and Spica departed for Metafalss. It would be later revealed that Mir aimed to save the world using the theories of Metafalica. Mir never revealed her name to anyone in Metafalss, and she hid herself within a robot she calls "Jacqli". The people around her began to refer to her too as Jacqli, but she never really minded it.

She became acquaintances with Laude, a native of the Third Tower, the Tower of Tyria. Although both of them back then aimed for the Heart of Gaea, Laude wanted the heart so that he would be declared as a hero in the Tower of Tyria. Mir worked with him for a while, until she took the heart for herself after Gaea was created. Unfortunately, the she deemed the heart as "too small" to suit her purposes. She returned the heart to Croix and his party, and joined them as a member.

To aid Croix and his party in their quest to realize their dream of creating Metafalica, Mir provided them insights about their missions, especially about the technology and history of the tower. She also provided them support firepower, something which became useful in the destruction of different obstacles for the party.
