Flesh Backbone was Umehara's Shikabane Hime who only appears in the anime adaptation as a non-canon replacement for Touma Sawamiya. She was a foreigner who had died in a plane accident on her way to Akihabara before she became a Shikabane Hime.
Flesh first appeared on episode 1 of season two when she was peeking outside Makina's cave who had news about her. She is a huge otaku as Umehara himself, although the two can have passionate arguments than Makina and Keisei over conflicts on two-dimensional vs. three-dimensional or doujinshi vs. figurines. Flesh is a bit immature, but can act serious sometimes during dangerous situations. She fights with small pistols, but could also use giant shirukens, as she used to incapacitate Saki and Itsuki.
