Robin Sena

Robin is the newest witch hunter at the STNJ (i'm pretty sure thats the name but cant remember what it stand for) she is only 15 and has just arrived from the convent she was raised in because she was orphaned as a child. Like most of the other employees at the STNJ she has witch blood in her, and her powers have manifested giving her the power to use fire as a weapon.

Amon

Amon is the leader of the STNJ team (excepting the boss Cheif Kosaka)and Robin is supposed to be his new partner. He doesn't talk much and hes not overly friendly to her (i think its because shes not ashamed of her powers and witch blood like he is or something). He doesn't seem to have any power but uses his orbo to defeat any witches he comes up against.

Haruto Sakaki

Sakaki is the former rookie of the team now that Robin has arrived his partner is Miho Karasuma.

Michael Lee

Michael Lee i found out was not just some crazy guy who never left the office (which i found out from the [adult swim] webpage).Michael is actually a super hacker who was caught(somehow since u know hes a super hacker) sneaking into the system and was given the ultimatum of work for us or die. He chose working for them and gives them pretty much all their info on the witches they r trying to capture hes not even allowed out without special permission which explains why everyone is so suprised when he just walks out of the building during one episode (which i of course just thought was weird but now i understand).

Miho Karasuma

Miho Karasuma has a power called psychometry, which means that when she touches someone or sometimes ever something they have touched she is able to pick up their thoughts and feelings helping her to get better info from crime scenes and witnesses. Her partner is Sakaki.

Yurika Dojima

Yurika Dojima is a spoiled brat type of girl whos parents thought she needed to work so they got her a job at the STNJ i'm not sure but i think she may also be a witch to but i'm not sure about her power just a passing comment about invinceability or something but i'm not sure. She is kinda lax about work and shows up and leaves whenever she likes but she is always supportive of everyone else and will be there when shes needed.

Cheif Kosaka

Cheif Kosaka is the boss at the STNJ but his job seems to mostly just relate orders down from headquarters and take care of any messes left behing when a witch is captured.

Takuma Zaizen

Takuma Zaizen is the bad guy in the show. He is at the top of the company heirarcy, but u don't really find out much about him until later on.
