Rokuson (禄存) is a Sika Deer shikigami used by Yura Keikain. He has extraordinary jumping power and the kanji for his name written on either cheek. In a manga omake, he apologizes for Yura's bad naming sense, but he is never seen speaking otherwise. He is named for the star Phecda of the constellation Ursa Major, which was called "Rokuson" in scriptures from China's Tang Dynasty.
