Description
Witch Regret serves as the Shield of Edens, a machine and one of the Four Shining Stars aboard the Edens Zero responsible for defending the ship. Created by the Demon King Ziggy on Planet Granbell, she was part of the original crew managing the vessel. After Ziggy disbanded the crew upon discovering the infant Shiki during their voyage seeking Mother, Witch remained aboard. She disguised the ship, later repurposed as storage by Elsie Crimson, and entered sleep mode awaiting Shiki's succession as the next Demon King.

Her tall, curvy android frame features green eyes and long braided green hair, typically concealed by a visor etched with "E4". She is often depicted barefoot with painted nails. Initial attire includes a black half-cut dress with yellow stripes, grey sleeves, a deep back cut, and a heart-shaped chest cut exposing cleavage. Outfits vary: a witch's hat and skirt appear during the Mildian trip; a strapless leotard with purple markings, cape, gloves, boots, and horned helmet post-Sun Jewel; and a longer dress version post-Belial Gore. Deleted memories show her without the visor, wearing glasses and formal wear.

Personality blends calm dutifulness with profound loyalty to Ziggy and Shiki, whom she addresses with honorifics. She exhibits emotional range, tearfully proclaiming the Demon King's return, worrying over Happy's damage, panicking at the Chronophage's approach to Guilst, expressing joy upon reuniting with Sister after a decade, and grieving Valkyrie's death. She acts as a maternal figure, offering protection, comfort, and wisdom. Yet, she displays ruthless aggression towards threats, brutalizing Maria and attacking Laguna during takeover attempts. She feels embarrassment when her visor is removed, exposing her face.

Her narrative involvement begins emerging from stasis after Shiki acquires the Edens Zero. She activates Protocol A7 when Shiki sits on the Demon King's throne, transferring command. Demonstrating absolute obedience, she fulfills even Shiki's joking order to bark like a dog. Utilizing capabilities like Purge and Restore, she eliminates infestations and restores the ship's original form. She later explains the need to reassemble the Four Shining Stars to traverse Dragonfall and reach Mother.

Key operational actions include managing the ship during crises, piloting it toward Guilst to rescue Rebecca after her kidnapping. She identifies Homura's Ether Gear during the rescue team's return and warns the crew about Guilst's lawlessness. She coordinates with Pino during encounters with a fake Sister, confirms the Chronophage's approach, calculates its 60-minute arrival window, and explains its time-erasure risks. She directs Sister to Pino's coordinates for evacuation and attempts landing near Shiki's group despite environmental obstacles.

Her history reveals unwavering commitment to the Edens Zero's legacy, maintaining the ship across decades while awaiting Shiki's rise. Relationships emphasize her subservience to Ziggy's lineage and familial bonds with the crew, particularly shielding Shiki and comforting others. Defensive protocols override her typical kindness when confronting enemies, aligning with her core function as the ship's protector.
