Dark Magician Girl, known as Black Magician Girl in the Japanese version, is a character in the Yu-Gi-Oh! manga. She is a spirit ka, which Mana could summon. Her Duel Monsters card is the "Dark Magician Girl".
Her appearance resembles that of her summoner, Mana. Unlike "Dark Magician Girl" appearances in other media, the manga Dark Magician Girl ka has tanned skin.
When Atem, Shada and Mahado, as Dark Magician, battled Bakura, at Kul Elna, Mana arrived with the other priests. She summoned Dark Magician Girl in time to rescue Mahado from one of Diabound's attacks. Mana was able to communicate with Mahado through Dark Magician Girl, expressing her joy to see him alive. As Dark Magician Girl was not yet capable of fighting, she gave her heka to Mahado, who had been weakened.
