Chain of Heaven is the Noble Phantasm of Enkidu, the clay-born companion of Gilgamesh in the Fate series, and the name is also associated with Kingu in Fate/Grand Order. In the story the chains are said to bind divine beings, growing stronger against gods, which is why the phrase carries such weight for fans. Clips of the line spread through Fate fan edits, anime compilations and short-form videos, where creators use it to mark a dramatic capture or turning point. Its short length and clear delivery have kept it useful for memes and battle edits long after its first appearances.
