Cordelia grew up in Arland with her childhood friend Rorona. Cordelia is a responsible yet stern person who has difficulties showing her feelings towards others. She gets easily embarrassed when Rorona calls Cordelia by her childhood nickname 'Cory,' especially if it's done in front of other people. She comes from a noble family, although her noble status was purchased. Like most people of Arland, she believes that system of nobility is outdated. She's aware of her stature and how people may treat her with her status, but she doesn't take much pride in the fact. She loves jewelery and gems, and will secretly have Rorona create them through the guild in Atelier Rorona. Cordelia's weakness is her short stature She's self conscious about her height, and angers instantly when it's mentioned. She hates Astrid for creating Hom only a few inches taller than her to purposely mock her height. She doesn't grow a single inch in 6 years time when she makes her appearance in Atelier Totori. When Cordelia sees Chim for the first time, she praises Rorona for making Chim shorter then her, and is ecstatic that she's not the shortest person that she knows. (Source: Atelier Wikia)

Amon is a Hunter and is also Robin's partner. Though at one point Robin asks what Amon's ability is, he never answers and is never revealed. Originally, he is reluctant to team up with Robin, as he is told to "keep an eye on her" by STN-J (Japanese branch) boss Zaizen, as Robin is sent from Solomon (headquarter). However, seeing her worthiness in cases concerning highly prominent witches, he eventually accepts her. Later on in the anime, Amon disrupts Zaizen's plan to eliminate or take Robin into Factory. Soon after, Solomon attacks STN-J, and once again Amon saves her. After that episode, Amon is not seen in STN-J anymore, but found to be working directly for Solomon. He is ordered by Solomon to hunt Robin, as she has learned the arcana of the craft and her powers have grown beyond Solomon's control. However, when meeting face to face with Amon, Robin fully accepts Amon's decision whether to kill her or not. Amon finds that he cannot kill her. It is revealed near the end of the series that Amon's father was a witch and his mother a "seed", indicating that Amon himself also carries the dormant witch trait. Amon fears the awakening of those dormant genes. Amon's mother willingly accepted his father's lead and she "awoke" as a witch and from then on, she no longer recognized young Amon. His fear and hatred for witches originated from that moment, though his behavior throughout the whole 26 episodes is neither particularly hateful nor fearful toward witches. At the last episode, when Robin realizes that her role was to make witches and humans live together in peace as "Witch Eve", Amon volunteers to be a watchman who would terminate her if she turns destructive. Amon and Robin's survival is not known, but Karasuma was with two of them until the last moment, and she emerges alone. Karasuma's unconcerned answer "don't know" suggests that Robin and Amon escaped safely. The relationship between Amon and Robin has not been any more than a professional relationship. However, Amon breaks up with Touko, Zaizen's daughter. They seemed to be already falling apart somewhat. Touko calmly accepts that and suggests that Amon "changed," suggesting that Amon has become a warmer person to say such things as "suddenly I thought of you and called." While Amon and Robin are never seen in romantic light, Amon repeatedly goes extra lengths to save Robin, and Robin would trust her life with Amon.
Michael is a hacker and the technical support expert in the STN-J. He is confined to the STN-J building 24/7 by the director Zaizen after being caught hacking into the STN-J's computer network (the only network he was unable to avoid detection in, as he states to Robin). Zaizen had given him the option of either working for STN-J or being killed on the spot, and Michael had opted for the former. Michael somewhat avoids Robin at first, but then begins to warm up to her, particularly when Robin stays behind in the office at night to accompany him. Michael is able to dig up extensive information about various witches, police reports, and the like, all the while covering his tracks. In the end, he is finally given permission to leave STN-J headquarters.
Nagira is an attorney and is Amon's older half-brother by the same father. He takes Robin in after she leaves STN-J, and he runs a private office with two assistants. He has Robin act as a bike messenger, partly because he does not believe the government is correct in persecuting witches. Throughout whole episodes, Nagira does not do anything but investigate. He gathers information in the streets by means of a man he meets in a pachinko bar as well as a witch in Wall City. Personality-wise, he appears to be the opposite of his brother, as he is talkative, goofy, occasionally lazy, and tends to do things his way.
