gamerant.com:

Finding the Four Shining Stars is Shiki's main priority in season 1 of Edens Zero, but who exactly are these femme-Fatales? The Demon King, Ziggy, created four beautiful machines to help the Edens Zero reach its full power potential as they travel across Universes. Each Shining Star works in tandem with one another, each responsible for a significant aspect in guaranteeing the crew's survival.

Sworn to protect the Demon King's predecessor, these alluring androids use their skills in attack, defense, support, and strategy to assist Shiki and the Crew — and only once all the Shining Stars are assembled, can the new Demon King begin with his true quest of finding Mother.

Edens Zero: Shiki Granbell's Story has a Grave Ending

Witch Regret shows the most maternal qualities of the Four Shining Stars and her protective instincts are the perfect catalyst for fueling her defensive powers. She shows a fierce loyalty towards Shiki and the Crew, intending to honor the late Ziggy's memory. When she was relieved of her duties to the Demon King, Witch Regret remained aboard theEdens Zero, in hibernation mode, awaiting the arrival of Shiki in order to assist him in finding Mother.

Witch Regret shows distinct defensive skills along with the ability to manipulate Ether much like a magician would do with magic. She is a master of the elements, possessing lightning, air, and ice attacks, along with her Ether Shield. Her intense loyalty leads her along a submissive path, often following commands regardless of how ridiculous. Shiki and Weisz regularly take advantage of her fidelity for their own perverted gain (not that many fans are complaining) but nevertheless, all members of the Edens Zero Crew look up to Witch for guidance and wisdom.
