Sister Miyako

The Second Neck (二の首, Ni no kubi), she is a purple-haired 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 co-operation among the Orochi, she seems to be the closest thing therein to a second-in-command and the most cool-headed of the lot; she can control Girochi and induce some semblance of cooperation among the three other female Necks.
