Also known as The Maid-san is a Witch, Maid-san wa Majo is a doujinshi drew by Takeuchi (who loves maids) after the release of Tsukihime. The work was released under Nasu and Takeuchi's doujin circle Bamboo Broom (竹箒), and is about a powerful sorceress being forced to wear an "Absolute Obedience Maid Uniform." (source: tsukikan.com)
