Reiko Oota

The Fifth Neck (五の首, Go no kubi), she is an antisocial mangaka of few words. Reiko continues her "day job" as a member of the Orochi and has in fact done better on the market since joining, though her manga have taken on very dark themes since then. She barely interacts with the other Orochi and is stone-cold in battle, though her level-headedness is more the product of cynicism and numbness than Miyako's. (Source: Wikipedia)
