This story is really suck with the devil way.

*Sighed*

Pretty good story, but unfortunately, it contradicts absolutely all the canon story that was established from the game, because of this:

Mir couldn't haven't made Despedia because that song only exists as a hymn crystal in Metafalss, and its only function is controlling the Divine Army robots.

Aurica and Mir aren't related in any way, except for the system error that gave Mir's hymn code to Aurica. (And Aurica would be dead at the time of the game if she really was her daughter, considering how long the Third-Generation Reyvateils live).

And Mir herself provoked the collapse of the right wing of Horus immediately after she seized the control of the Silver Horn and killed off all the humans that were in the area, and at that time, she didn't regret it at all.

And Jakuri is only the name of robot, everyone just calls her that because no one knows her true name in Metafalss.

I love the Ar Tonelico series, and your story was really good, and i can't wait to read the next chapter^^
