Sister Miyako

The Second Neck Ni no kubi she is a purplehaired nun who is the first Orochi to appear and attack having lost her faith due to living through a terrible war presumed somewhere in South America due to her tanned skin color which is a common stereotype in manga and anime. Although there is little cooperation among the Orochi she seems to be the closest thing therein to a secondincommand and the most coolheaded of the lot she can control Girochi and induce some semblance of cooperation among the three other female Necks. from wikipedia
