Enkidu

Enkidu: Chains of Heaven (天の鎖エルキドゥ, Ten no KusariErukidou) is a weapon most trusted by Lucifer, he regards it as important as Maria or Requiem of the Phantom. It is a chain named after his closest friend, who died during the Alabastian War, made to bind the gods so they cannot escape, making it an anti-divine weapon that holds the concept of "reigning over the Gods." Due to the fact Lucifer holds it in such high regards, he only believes it should be used against worthy opponents.

The strength and durability of the chain grows stronger depending on the targets strength. Divine targets are completely held in place due to the weapons original intention. It does have some sort of limit, as even he is able to tell that the chain is not enough to completely bind Hydra. When the chain itself is coated in Armament Hardening, no force in the entire universe can break it.

Lucifer is capable of taking out the entire length of chain from the Gate of Babylon to use in conjunction with Ea or Requiem of the Phantom when he is serious about fighting, or he can simply summon part of it from the Gate. The chain can be summoned from anywhere the Gate of Babylon can reach, elongate and contract without any shown limit, and multiple individual sections can be summoned at one time. The blade on the front of the chain is capable of acting as a striking weapon when launched at a high speed, he has been shown to use Color of Armaments: Hardening or God Blade to increase the striking power of the blade. Lucifer can summon a single length to wrap around an opponent so he can drag them towards him by pulling it. Even against non-divine targets ,it is still a weapon nearly impossible to pry off once it has gotten a hold of them.

Lucifer generally binds the opponent's weapon, limbs, shoulders, neck, and abdomen, rendering them completely immobile. The chains continuously twist and tighten with enough force to attempt to tear off Ceaser's head and bend his arms past their limits in a normally impossible direction. Enkidu was placed with the spell Phantasma which permits it to touch intangible beings such as spirits.
