Souga Kagutsuki ("Soga Kagustuki") | Kagutsuki Souga 輝月 宗牙 （かぐつき そうが）
Shizuku and Rin's "brother" (in the non-familial sense), he is a man of considerable clout among the Nighteaters. Because Nighteaters possess such extremely long lifespans, it's fair to say that he's been alive for far longer than most could ever know. Physically, his tall and handsome physique -- along with his unique wardrobe choices -- often see him mistaken for a foreign tourist in Akihabara. In actuality, he seems to be enacting some form of unholy master plan centered around the Synthisters in an effort to save his dying race... no matter the cost.
