Similar to its predecessors My-HiME and My-Otome, the title is a pun, which derives from the visual similarity of the Latin letter "Z" (from the German word zwei "two") to the kanji "乙", the first of the two characters in the word 乙女 otome "maiden". On the logo, the two similar glyphs are shown superimposed on one another.
Plot
My-Otome Zwei takes place one year after the events of My-Otome. Arika is now a full-fledged Otome (though still under the tutelage of Miss Maria as she has not yet received enough credits to graduate) and Nagi is incarcerated in a prison somewhere in Aries. The various nations are at peace with one another and plan to hold S.O.L.T. (Strategic Otome Limitation Talks) to discuss limiting the numbers of Otome.
A mission to destroy a meteor threatening to collide with Earl sets into motion a chain of events which result in a mysterious shadowy figure attacking Garderobe and several Otome as well as a new, more powerful version of Slave appearing across the planet. To make matters worse, Queen Mashiro disappears following an argument with Arika. The series follows Arika's search for Mashiro as well as Garderobe's attempts to uncover the truth behind the shadowy figure.

In 2007, My-Otome Zwei was serialized as a single-volume manga in Champion RED. The art was done by Chako Abeno. Having nothing to do with the original My-Otome manga, it followed the storyline of the OVA at first but later diverged.
