The Maiden in Black is a character in Demon's Souls. She is a demon and is able to manipulate Souls.

She uses the souls gathered by the player to level up by selecting "Seek Soul Power".

After all other major bosses are defeated, the Maiden in Black takes the player to The Old One, where he/she fights King Allant. After the player's victory, the Maiden in Black attempts to lull the Old One back to slumber. Killing her or sparing her impacts the ending of the game.
