A spin-off of My-HiME.
My-Otome’s story takes place in the distant future on the planet Earl, colonized by immigrants from Earth centuries ago. “Old technology” has survived in the form of nanomachines that allow female virgins to take the role of Meister Otomes – bodyguards, attendants and warriors that serve the royalty of various kingdoms.
Arika Yumemiya has come to Windbloom Kingdom in search of her mother, whom Arika knows was an Otome. On her arrival she meets the top Coral Otome student, Nina Wáng, and Windbloom’s heir to the throne, Mashiro Blan de Windbloom. The series follows Arika’s progress as a student at Garderobe Academy and the machinations of those desiring the destructive power of the old technology for themselves.
