My-Otome Zwei

_My-Otome Zwei_ takes place one year after the events of _My-Otome_. Arika is now a full-fledged Otome, 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 number of Otome. A mission to destroy a meteor threatening to collide with Earl sets into motion a chain of events that results in a mysterious shadowy figure attacking Garderobe and several Otome, while a new, more powerful version of the Slave appears across the planet. To make matters worse, Mashiro disappears following an argument with Arika. The series follows Arika's search for Mashiro and Garderobe's attempts to uncover the truth behind the shadowy figure.
