Sayaka Yabunmusan

Sayaka Musanyabun (霧散夜分=明か, Musanyabun Sayaka) is the sole remaining member of the Musanyabun Clan. After her clan was wiped out by a certain azure haired man, Sayaka escaped to Rukongai, where she met the also-fleeing Setsuna Kawahiru. The two became fast friends, due to their cirumstances and compatible personalities. Several years later, Sayaka and Setsuna enrolled at the Shinō Academy, where Sayaka aided Setsuna with her steep learning curve. After graduating, the two were offered positions as instructors at the academy. Sayaka saw this as an oppertunity to stay close to her best friend, and quickly accepted after learing of Setsuna jumping at the chance as well.

Personality and Traits
Sayaka is a somewhat quiet and rather shy young woman. At first glance, she seems rather agreeable, to the point of being submissive, especially to Setsuna, but underneath this, Sayaka is shown to have an iron will, and can be rather stubborn and bull-headed when it comes to decisions she believes will hurt others if plans are wrongly executed, and as Setsuna states, "she's like a damn ox...". Her relationship with Setsuna is one of the closest around; the two are almost inseperable. Sayaka is rather pacifistic, and would rather be a noncombatant, preferring to find a more peaceful solution to quarrels, however, she will fight if it is absolutely neccessary. Sayaka has romantic feelings for Setsuna, a fact that Sayaka attempts to hide from her due to fear of being rejected. Sayaka is absolutely devoted to Setsuna, and is willing to go to incredible lengths to make sure that she is happy, though most of the time, she is often going against her own personal beliefs to do so. When Setsuna was hospitalized due to an encounter with several Vasto Lordes, Sayaka sat by her bedside for three weeks without leaving once. Sayaka attempts to take on a motherly-sisterly role towards Shion, and is often seen trying to help her grasp basic concepts of Shinigami arts. Gai Nagareboshi and Sayaka get along rather well, and can cooperate perfectly to realize their seldom joint plans. After Setsuna went mad due to a number of contributing factors, Sayaka decided to attempt to snap her out of her frenzy, taking a more central role within the story. During their battle, Sayaka attempted to call out to Setsuna and force her to remember all the "fun we had together", only to be shot down by the insane Kawahiru clanswoman. In the climax of their battle, Sayaka aquired a mutual kill with her most important person, dying peacefully with Setsuna.
