Wizard, in regards to your latest post, I would like to point out somethings. 

1: "Nothing More than a tough chain" - incorrect - the part about Enkidu being nothing but a tough chain to normal humans only applies to the physical aspect. They can squirm and fight all they want, but it's still a normal human fighting off a tough chain. Even with the target not being divine the other dimensional, spatial and conceptual trappings still apply, but at the similar reduced strengths.

And this is still assuming that the target does not have divinity, which I will get to next... 

2: "To normal humans and other non-divine beings" - True. Mia could probably break out of those bonds if she was non-divine and used the same amount of strengths and powers. IF. Mia's greatest strengths, the black blood, unfortunately, doesn't quite cut the trick. Why? Because black blood is divine. 

Let met explain. 

In soul eater, Crona got black blood injected into him because black blood contained the same soul wavelength as a kishin. As such, it can be reasonably deducted that a user of black blood has the same traits as a Kishin. Now, a Kishin is a demon "god". You may claim that's just a name, but in soul eater Kishin are said to have powers rivalling Shinigami himself. They are mythological. They are creators. 

They are divine, and so is anyone who shares traces of their wavelength. 

In Fate/Zero, the King of Conquerers, Alexander the great got divinity counted against him when he was trapped by Enkidu because of a simple MYTH. Mia, with her Kishin divinity - quite dark for divinity, but still divinity - would be under the same punishment. Even then, she would have to break out of Enkidu by force, as by stopping the very space around her she wouldn't be able to pull out more black blood at the moment. 

As such, Mia isn't getting out of Enkidu.
