Do Majo, also known as The Anger Witch, rules Jewel Land as one of the Four Great Magicians. Her symbolic color is red, represented by a signature red diamond-shaped jewel. She wears an outfit combining indigo-blue, dark red, and orange-yellow hues.

Her name directly embodies her core emotion: written in Kanji as 怒魔女, "怒" (do) means "anger" or "madness," while "魔女" (majyo) translates to "witch." This essence of rage defines her character. Subtle design elements, including diamond-shaped earrings and jewels, suggest a connection to the ace of diamonds playing card.

In the French dub, her name becomes "Mage Furieuse" (Furious Mage), reinforcing her central trait. Alongside her counterparts representing ease (Raku Majo), joy (Ki Majo), and sorrow (Ai Majo), she governs Jewel Land's magic from the Jewel Tower. The available information details these foundational traits and her role within the quartet, without extending to background stories, character development, or alternate identities like "Amber."
