Anacondy administers Eternal, overseeing operations and enforcing strict compliance among members. She possesses purple hair resembling snakes, pale skin, green eyes, and wears a green coat with orange lining, an orange scarf, yellow neckerchief, black belt, yellow leggings, and black boots. Her duties involve collecting subordinate reports, controlling rare objects acquired by Eternal, and ensuring the authenticity and quality of presented items. She exhibits a judgmental, demanding personality, frequently arguing with employees like Nebatakos and Shibiretta over incomplete paperwork or perceived incompetence. She demonstrates clear favoritism, approving Mucardia's holiday request while rejecting Bunbee's without justification.

Her primary motivation is unwavering devotion to Eternal's leader, the Boss. She performs duties rigorously to gain his approval, including using her abilities to petrify adversaries like Pretty Cure and Milky Rose for his collection. This loyalty manifests as obsessive jealousy when the Boss expresses interest in Flora, guardian of the Cure Rose Garden. Anacondy despises Flora, blaming her for disrupting her relationship with the Boss and actively seeking Flora's demise. Before the main events, she intercepted Syrup, a mailboy delivering a letter from Flora to the Boss, erasing his memories to prevent communication.

In combat, Anacondy commands formidable power after transforming into her true form. She excels at hand-to-hand combat, defeats Milky Rose with ease, and petrifies opponents into stone. She also summons energy blasts and deploys Eternal's Hoshina creatures for offensive operations. Her role typically involves minimal field action until later stages, when she directly confronts Pretty Cure. She punishes subordinates severely, turning Nebatakos' headphones to stone and attempting to eliminate Bunbee by confining him in the organization's basement. She later fires Nebatakos for bringing Pretty Cure to Eternal headquarters.

Anacondy's storyline culminates in profound emotional conflict. After exhausting her energy to petrify Pretty Cure for the Boss, he dismisses her efforts, fixating solely on Flora. Consumed by heartbreak and fury at his rejection, she attacks him but is swiftly destroyed. Her final moments show her reaching toward the Boss before disintegrating. This occurs after Eternal's invasion of the Palmier Kingdom and surrounding realms seeking the Rose Pact and keys to the Cure Rose Garden.
