2016 Anime Villains Tournament - Round 1 Group 54
A group of quality villains I can actually vouch for since I've seen all these shows/movies.
Nui Harime - Kill la Kill
Satoshi Batista - Michiko & Hatchin
Ryouko Asakura - The Disappearance of Haruhi Suzumiya
Kasane Kujiragi - Durarara!!x2
Kujiragi isn't quite as well-characterized as Izaya, but that's really only because she's a recent addition to the cast.
I'll give her my extra vote, while my main will go to Nui.
Actually I'll do the reverse.
Even though he got taken out like a bitch, when he was at his prime Satoshi was a true beast to be reckoned with. So double votes to him.
Poll vote goes to Kasane Kujiragi, extra vote goes to Nui Harime.
Main vote goes to Nui Harime, extra vote goes to Satoshi.
