My-Otome Manga
In the My-Otome manga, two versions of Fumi exist. The first is Fumi the Predecessor of Garderobe; the only difference between her and her anime counterpart is that Fumi is able to communicate with the students and staff through various statues and robots of her image scattered throughout the grounds (an enormous, unmoving statue of her holding a scythe can be prominently seen mounted above her own burial site until her ultimate death). The second is Fumi Himeno, the HiME reincarnated by Mashiro blan de Windbloom's magic. She carries a scythe, and is loyal to Mashiro, whom she serves as a maid; however, it is eventually revealed that her true master is Sergay, who orders her to kill Mashiro (she proforms this duty without a second thought).
One interesting note on HiME Fumi's presence is her ability to control the Predecessor Fumi; she is instructed by Mashiro to 'absorb her' (Mashiro refers to the Predecessor as Fumi's 'fragment'". This results in Otome Fumi's teleportation from the Predecessor core to the manga's Ultimate Black Diamond,implying that while there is a direct link between the HiME and their My-Otome counterparts, they do not necessarily share the entirety of a soul.
After the death of princess Mashiro, Sergey summons the Predecessor Fumi from within the diamond, and commands her to fight Manshiro, Nina and Arika. With the addition of Erstin to the fight, this ends in defeat for Fumi. Afterwards, Mashiro sees Fumi and Lena, the former and new Predecessors, together in a vision.
