The 'First Otome' that lived 300 years ago who possessed the ultimate GEM called the True White Diamond . She basically single-handedly ended the destructive 12 Kingdom War and founded Garderobe. However, during that time, her GEM turned into the "Ultimate Black Diamond" after sensing human despair. During Shizuru and Natsuki's materialization sequence, the initials F.H. indicates that Fumi Himeno is indeed their Master, but how this actually works is unknown. In the manga Fumi's consciousness exists as an AI system, and in the anime her consciousness selects new Columns. It is speculated that her body is kept in stasis in a chamber deep underneath the Academy. In episode 17, a large orb resting deep under Garderobe is seen bearing her name, implying that it is either a large computer imbued with her consciousness (as in the manga) or a cryo-chamber. In episode 19, it is confirmed that it is Fumi's body resting in the chamber, preserved and "asleep." When it is disconnected, the five columns and all the students whose Robes were released during the emergency lose their ability to materialize, though Otome's with private masters (such as Arika and later Nina) retain their powers.
