"O child of man, bind fast the gods."
Rank: A++ Type: Anti-Purge Noble Phantasm
Enuma Elish.
Enkidu transformed his own body into a divine armament.
He converted a vast amount of energy into a wedge that pierced through and bound the enemy tight.
Enkidu had originally been a weapon dispatched by the gods to "return Gilgamesh to the gods."
Gilgamesh himself was the "Wedge of Heaven," created to prevent gods and men from drifting too far apart, but Gilgamesh rebelled against the gods.
Thus the gods sent out Enkidu, hoping he would bind Gilgamesh and bring him back to the heavens.
And yet Enkidu became Gilgamesh's dearest friend.
This "chain that could bind even the heavens," in accordance with his dear friend's wish, chose the path of being used for humanity.
Logically speaking, Shiro's imitation should not have been capable of releasing its Noble Phantasm, because the Noble Phantasm itself was actually Enkidu, not the chains.
However, as Shiro delved deeper into studying his own Enkidu, he discovered that it had the faintest difference from the Enkidu recorded in the database.
And it was this tiny difference that let Shiro see hope of releasing the Noble Phantasm.
The hope of releasing a Noble Phantasm like other Heroic Spirits!
Shiro did not want to release himself along with the Noble Phantasm the way Enkidu did, though Shiro was admittedly very curious what state he would be in if he truly turned into Enkidu.
The current release method was the result of Shiro's research: changing the release condition of "sacrificing the entire body" to sacrificing part of the body.
In truth, the ideal state would have been to sacrifice a clone that shared Shiro's origin, but unfortunately, that had failed, so he could only switch to an arm—and he still wasn't certain
