The Gate of the Archer Key is one of the twelve Zodiac Gate keys used by Celestial Spirit Mages to summon the Archer, Sagittarius.
Sagittarius Key


The key is a golden Celestial Spirit Key, with the bow of the key being circular with a white circle in the middle, stamped with the crest of the Archer, colored in green while the handle and blade are designed to look like an arrow.


While in possession of the key, a Celestial Spirit Mage may be able to summon the Archer Sagittarius by reciting the quote, "Open the Gate of the Archer! Sagittarius!". This summons Sagittarius, a man wearing a horse suit, carrying a bow with a quiver of arrows strapped on his back.
