The manga proved popular, and was adapted into two anime series jointly by Gainax and Shaft: “Mahoromatic: Automatic Maiden” and “Mahoromatic: Something More Beautiful”.
The first series consisted of twelve episodes and ran from September 10, 2001 to January 28, 2002 on BS-i in Japan, and more or less followed the manga to the third volume.
The second series also followed the manga, culminating in the story’s end. This series ran from September 26, 2002 till January 16, 2003.
A television special, “Mahoromatic: Summer TV Special”, set in the days when Minawa had become a regular part of the household, was produced and aired around Summer 2003.
A two episode special entitled Mahoromatic: Tadaima Okaeri was announced on August 22, 2009. It aired on October 17 and October 24, 2009. It takes place during the second series, on days 270-268 of Mahoro’s life timer.
Originally the anime was licensed by Pioneer Entertainment (later Geneon Entertainment). As of October 2008, ADV Films had announced that they had regained licenses to both Mahoromatic, and Mahoromatic: Something More Beautiful, through its new Japanese licensor Sentai Filmworks. Currently, the anime is now distributed by Sentai Filmworks (however, the Ep00 Special and Year End Special are absent). They also recently acquired the Mahoromatic: I’m Home special, with the English dub to be produced at Bang Zoom! Entertainment.
Mahoromatic including both seasons and the summer special is currently available through The Anime Network’s free video on demand service, found on many cable systems and DirecTV.

As Suguru is in critical condition, Mahoro reappears alive, asking to take him home.
