|Great Swamp Cuculus|
Can be summoned as a white phantom for the Old Demon King. Her summon sign is located at the base of the stairs leading to the fog gate.
- Defeating the Old Demon King with her assistance triggers the appearance of a corpse next to Cornyx's cage in the Undead Settlement with her equipment on it: Cornyx's Garb, Cornyx's Wrap, Cornyx's Skirt and the Spotted Whip which implies that she used to be Cornyx's pupil.
