Kaaya is an Oracle who specializes in defensive and healing spells. She meets Jil after he injures himself fighting a group of Climbers, and she takes him to her house and heals his wounds. He later joins her and Ahmey's climber party. She uses a long wand and is at time seen placing small runes into a slot at the top to perform certain spells.

She is a descendant of Ki, who aided Gilgamesh in his battle against Druaga.
