Witch, known as the "Shield of Edens", is a machine and one of the Four Shining Stars that manage Edens Zero. Witch is very dutiful and she holds a deep respect to Ziggy and his adoptive grandson Shiki. Although she is usually emotionless, Witch is capable of showing emotions as she shed tears while proclaiming the Demon King's return to Edens Zero, expressing worry over Happy when he was damaged, panic when a Chronophage was making its way to Guilst, happiness when seeing Sister again for the first time in ten years,and grief when learning Valkyrie had died three years ago. She finds it embarrassing to show her face to other people. However, without her visor, Witch's face is described by Rebecca as beautiful.
