Claudia Enfield (クローディア・エンフィールド) is the student council president of Seidoukan Academy.
Claudia has long, wavy blonde hair with a split bangs at the crown of her head, and purple eyes. She wears the Seidoukan Academy uniform jacket, but paired with a blouse with a frilly high collar and three-frilled sleeves, and a two-tiered ruffled skirt. She wears dark boots, and stockings with garters.
During the time before the Lindwurm, Claudia grew out her hair and braided most of it in a ponytail. In addition, her uniform jacket now bares her shoulder areas.
Claudia is refined, friendly, and intelligent. As Student Council President, she oversees most of the school's affairs herself, and is always well informed about the going-ons in both her own school and the other schools. When with Ayato, she displays a sly and coy side, frequently teasing the hapless Ayato.
When alone with him, however, she shows a weak, delicate, and vulnerable nature. Claudia states herself as "usually quite pure/well-behaved" but also "scheming", and Ayato states her ways as "not quite ruthless". She also consistently refers to herself as "black-hearted" and is referred to as such by other high rankers from Asterisk schools.
Claudia has attended Seidoukan Academy since the first year. She became Student Council President in middle school and has had three terms thus far. She has some sort of background with Julis, having visited Lieseltania on multiple occasions. Her mother is also an esteemed member of Integrated Enterprise Foundation.
She participated in the previous Gryps but their team lost to Saint Galahadworth Academy's Team Lancelot, though despite the loss she was able to destroy Laetitia Blanchard's emblem. She also was said to have not been fighting at full strength during this fight as she was not even tired afterwards.
Orga Lux: Claudia wields the Orga Lux Pan-Dora which allows her to see up to 300 seconds into the future. The cost is seeing nightmares depicting her own death every time she sleeps. It never shows her the same death twice but an array of different methods. She ironically refers to her Orga Lux as her "little darling" and says it is the worst of all Orga Lux personality wise.
Genestellar (星脈世代): As a Genestellar, Claudia has enhanced physical ability and an aura known as prana.
Claudia takes deep interest in Ayato from the moment she first encounters him, protecting him from Julis' wrath and declaring their duel void. It's revealed that she was the one who pushed for Ayato's entry as a special invitee to Seidoukan Academy, despite the fact that he wasn't well known. This was later revealed to be because Pan-Dora never had Ayato kill her in her dreams, causing her to fall in love with him, leading to her efforts in admitting him for her plan. She later confesses but retracts it to confess again another time.
- According to the author, Claudia's birthday is June 10th, her horoscope is Gemini, and her blood type is AB.
- Claudia has been Student Council President since some point in junior high, having had three terms. Assuming that Seidoukan Academy (and the other schools in Asterisk) uses the same school system as Japan, this would imply that Claudia has been president since her second (and middle) year of junior high, as she is currently a high school first-year.
