Ki (カイ, Kai) is a priestess from the kingdom of Babylim and a close friend of Gilgamesh. When the kingdom was taken over by the Sumer Empire and later by the demon Druaga, Gil was enslaved and got hurt during his tasks. Ki nursed him and wished to do something to help him and make the kingdom return to normal. Ishtar attended Ki's prayers and told her that she must return the Blue Crystal Rod, giving her a magic tiara to protect her during the quest.
In The Quest of Ki, Ki goes inside the Tower of Druaga to recover the rod and meets the holy dragon Quox, which helps her by showing shortcuts. After reaching the 60th floor of the tower, she discovers Druaga had split the Blue Crystal Rod into three rods, and Druaga captured her by transforming her into stone, rendering her powerless.
In The Tower of Druaga, Gil manages to defeat Druaga and saves Ki, returning her to her original form.
In The Return of Ishtar, Ki and Gil must find a way out of the tower. Ki can use the Blue Crystal Rod to attack with fireballs, and she learns other magic attacks during the game.
Three years after Druaga's defeat, Ki and Gil would soon marry in The Nightmare of Druaga: Fushigino Dungeon, but Ki is kidnapped by Skulld and sealed in the basement of the Dark Ruins from the Tower of Druaga. After Gil manages to free her, Ki and Skulld disappear.
Ki is mentioned in Seme COM Dungeon: Drururuaga and can be summoned with the Spell Card #25.
"Young Ki" is a playable character in Druaga Online: The Story of Aon.
