Chirithy

The Chirithy are cat-like, anthropomorphic Dream Eaters that appear in Kingdom Hearts χ and act as companions to Keyblade wielders. They were created by the Master of Masters and oversee their respective Keyblade wielder's progress, putting them through trials and offering assistance to them. The Chirithy support all five Unions, and though they are not subordinates to the Foretellers directly, they work together with them to drive back the darkness. A Chirithy is bound to its chosen Keyblade wielder; in the event that their Keyblade wielder succumbs to the darkness or vanishes, so does the Chirithy.
