Evangeline Athanasia Katherine McDowell, commonly known as Evangeline A.K. McDowell, originated during the Hundred Years' War in Europe, likely in Scotland or Ireland based on her surname. She was the ward of a castle lord until her tenth birthday. An unknown sorcerer then transformed her into a Shinso vampire ("True Blood Vampire" or "True Ancestor") during her sleep, bypassing the typical biting method. Awakening, she discovered she had unknowingly fed on a castle resident and fled immediately into winter surroundings to avoid persecution. Initially possessing standard vampire weaknesses like sunlight vulnerability, she eventually overcame these to become a "high daylight walker." Her quest for revenge led to the killing of her creator, later revealed as the immortal Mage of the Beginning conducting experiments on immortality. Centuries of itinerance followed due to her ageless appearance, including an instance where she was captured and burned at the stake, though this failed to kill her. In recent history, Nagi Springfield ("Thousand Master") saved her life. She developed romantic feelings for him and pursued him relentlessly until he tricked her in Japan by exposing her to an "anti-vampire soup" containing garlic and leeks. Using the Infernus Scholasticus (School Hell) curse, Nagi confined her to Mahora Academy's grounds and restricted her magical abilities. He promised freedom upon her graduation, but his disappearance five years later left her trapped until the arrival of his son, Negi Springfield. The school dean, Konoemon Konoe, employed her as a security guard to monitor campus activities. Initially antagonistic towards Negi, she claimed draining his blood would break the curse binding her to Mahora. She attacked him early in his tenure as a teacher, though her true intentions regarding the blood-draining claim remained ambiguous. After witnessing Negi's potential during the Kyoto incident, where she intervened to defeat Fate Averruncus and the demon god Ryōmen Sukuna-no-Kami, she agreed to become his combat magic instructor under strict conditions: daily menial servitude and blood payments. This arrangement contradicted her earlier assertion about blood-draining nullifying the curse, suggesting incremental consumption might be insufficient or that complete drainage was necessary for a power boost to overcome the curse. Her personality blends centuries-old cynicism with rare vulnerability. She presents as cold, arrogant, and dismissive, often referring to her age (over 600 years) and expressing frustration at being perceived as a child. Nicknames like "Dark Evangel," "Doll Master," and "Queen of the Night" reflect her fearsome reputation, with a six-million-dollar bounty on her head. Despite this, she enjoys quiet activities like Go and tea ceremony, demonstrating a subtle appreciation for Japanese culture. She exhibits genuine care for select individuals, notably her synthetic companions Chachazero and Chachamaru, and later develops a protective, almost maternal bond with her students. Though easily bored during peace, she masks deeper sensitivities, such as anger at being called "little" or "shorty" and concealed kindness that surfaces in critical moments. Physically, she appears as a 10-year-old Caucasian girl with blonde hair, blue eyes, and a height of 130 cm, maintaining a Gothic Lolita fashion style. Her agelessness stems from her vampiric transformation freezing her physical development. She can project an adult illusion using magic or specialized pills to blend into human society, adopting the alias "Yukihime" in later centuries. As a Shinso vampire, she possesses immense physical strength, speed, flight, regenerative capabilities (regrowing limbs unless destroyed or unrecovered), and immunity to conventional weapons. Weaknesses include an aversion to garlic, onions, and leeks due to heightened senses, and an inability to swim. Her mastery of martial arts, particularly aikido learned directly from Morihei Ueshiba 80 years prior to the main events, allows her to overpower skilled fighters like Setsuna Sakurazaki. She wields "Doll Master" abilities, manipulating foes as puppets via invisible threads or vampiric hypnosis, and commands hundreds of animated dolls within a 3km radius. Magically, she specializes in ice and dark elemental spells, ranking among the world's most formidable mages. Signature techniques include *Nivis Casus* (Ice Blast), *Iaculatio Grandinis* (Hail of Spears), *Anthos Pagetou Khilion Eton* (Thousand Ice Flowers), and high-tier spells like *Kosmike Katastrophe*, which generates an absolute-zero field. She created the forbidden art *Magia Erebea*, which fuses offensive magic with the user's soul to amplify power—a technique later adopted and modified by Negi. Additional capabilities include pocket dimensions (e.g., her training resort), illusions like the time-dilating *Phantasmagoria*, teleportation through shadows, and clairvoyance via crystal balls. Her character arc evolves from antagonist to mentor and ally. After training Negi, she tests his growth during the school festival by lending Chachamaru to Chao Lingshen without intervening directly. She later trains Asuna Kagurazaka rigorously, forcibly taking her as a third apprentice. Post-Negi's era, Nagi freed her from the Mahora curse after his rescue from the Mage of the Beginning. Adopting the name Yukihime, she founded and led UQ Holder, an organization of immortals. Two years before *UQ Holder!*, she turned the dying Touta Konoe into a vampire at his parents' request, raising him as her own. Centuries earlier, during her youth, she met Touta in a time-distorted realm under the alias "Kitty," forming her first friendship and romantic attachment. When an adult Touta professed love and proposed after Dana's training, she rejected him outwardly but privately cherished the gesture, noting he was "five hundred years late." In distant future timelines, she participated in humanity's conflicts, including serving as a UNSC Marine Corps colonel during the Covenant War. Using her alias Yukihime, she evaded detection while manipulating descendants of powerful mages into her 3rd Marine Special Operations Division, training them as combat mages aboard the magic-enhanced UNSC *Yamato*. She later aided in defending Earth during the Covenant invasion.
