Pandora

Pandora is known as the Witch of Vainglory (also translated as the Witch of Vanity) in Re:Zero − Starting Life in Another World. She is a mysterious, supernumerary witch separate from the main seven Witches of Sin, with a deep but taboo connection to the Witch Cult, over which she appears to hold significant influence or authority.

She possesses an otherworldly, inhuman beauty described as terrifying—long, transparent platinum hair that glows softly like sunlight, deep blue eyes with slit pupils, and a delicate, petite frame—often said to embody the ideal of human beauty so perfectly that merely seeing her can make people tremble in awe or fear.

Her personality appears calm, dignified, and graceful on the surface, but she is extremely selfish, sociopathic, and willing to commit any atrocity to achieve her enigmatic goals. She has orchestrated or been involved in major tragic events in the story's history (such as the incident in Elior Forest), and her true origins and full motives remain largely shrouded in mystery.

Her Authority of Vainglory grants her the terrifying ability to rewrite reality, phenomena, causality, or even memories to suit her will, making her one of the most dangerous and unpredictable figures in the series.
