Matsumushi
Matsumushi is a very young little girl that seems to have exceedingly good eyesight. When first shown during episode 1, it is revealed that Matsumushi is meant to be "the eyes of Seimei, while Seimei is meant to be "her ears". However in truth, Seimei can see perfectly fine without Matsumushi. Matsumushi seems hold a large amount of various medicine with her, such as in the case when she handed medicine to Seimei when they were in quick need of healing the Capital's emperor. Because Matsumushi can not say a single word, it is not known if she follows Seimei through affection, or through configured loyalty set by Seimei. Either way, Matsumushi seems to follow Seimei to any area and is occasionally seen as Seimei's second half. When Urabe later takes the Magatama of Fire after hearing of Seimei's distorted words, Matsumushi personally decides to follow after her. Unlike every other member of the Capital however, Matsumushi is the only one who found Urabe. Matsumushi then unleashes a knife from her right hand and smirks, which may conclude that she has some sense of a killing instinct. However, it seems that Matsumushi left after she stabbed the knife within Urabe's back, in which she was probably hoping that Urabe would die suffering. After Matsumushi then heads back and hands the Magatama of Fire to Seimei, the magatama is soon placed on the elemental table. A large amount of blue body destroying fumes are activated through Enmity, in which the Minister's of Right and Left were literally disintegrated. This amazing force of power throws Matsumushi violently into the wall, where she seems to utter words that can't be spoken, and reaches for Seimei with tears flowing from her eyes. Matsumushi then dies after the section that Seimei was in exploded with Enmity. Thus, Matsumushi had great affection towards Seimei in the end and may have felt some level of betrayal before her death.
