Movie
Description
Ais Wallenstein stands among Orario's strongest fighters as a first-class adventurer and executive member of the Loki Familia, bearing the alias Sword Princess for her exceptional combat skill. Her physical traits include long golden-blonde hair, gold eyes, and a slender build. She typically wears white and black battle cloth with black arm covers, long blue boots, and armored components like a breastplate and knee guards. Outside the Dungeon, she favors a white one-piece dress accented by gold lining.

Joining the Loki Familia at age seven after her parents fell to the One-Eyed Black Dragon, she forged her existence around vengeance, nurturing an intense hatred for monsters. Childhood trauma left her with lifeless eyes and a fragile demeanor, earning her the moniker "Doll Princess" alongside volatile aggression and disregard for authority or safety. Early in her career, she served as a supporter for other adventurers, achieving record-breaking progression by becoming the fastest to reach Level 2—a feat later surpassed by Bell Cranel. She maintained this rapid pace, ranking up roughly every one to one and a half years.

Quiet and reserved, Ais struggles to articulate emotions, often appearing enigmatic or mentally youthful. She visualizes a younger version of herself during vulnerable moments, such as offering Bell Cranel a lap pillow. Despite her strength, she refrains from belittling weaker adventurers. Her relentless willpower drives exhaustive training and strength acquisition, historically manifesting as self-destructive tendencies. Mentorship from Loki Familia executives Finn, Riveria, and Gareth tempered these impulses by emphasizing mental resilience, technique, and rest, though her core hatred for monsters persists.

Ais develops a distinct fascination with Bell Cranel after rescuing him from a minotaur, initially drawn to his rabbit-like appearance. She assists his training, shields him from peers, and displays uncharacteristic joy in their interactions. Their bond deepens through shared events like her tending his injuries on the 18th Floor and accepting his dance invitation at an Apollo Familia ball. Trauma surfaces in specific triggers: she avoids water due to childhood "swimming training" with adamantite weights and reacts violently to unwanted touch.

In combat, Ais specializes in fighting monsters, wielding wind magic "Ariel" for three-dimensional mobility and physical augmentation. This magic manifests as black or white winds, amplifying her strength to shatter adamantite and overwhelm foes like Revis. Her skill "Avenger" heightens abilities against monsters but clouds judgment, reverting her to a vengeful state. As a Level 6 adventurer—achieved by solo-slaying the 37th Floor boss Udaeus—her physical prowess outstrips most contemporaries, though she remains less adept against human opponents.

Her worldview evolves during the Xenos incident. Initially rejecting monster-human coexistence, she reconsiders after witnessing Wiene’s empathy and Bell’s resolve to protect her. Post-training with Ottar, she concludes that monsters may harbor human-like emotions while people can possess monstrous hearts, vowing to personally judge whom to classify as a monster. She guards her past closely, confiding only in Loki and top executives.

During the "Arrow of the Orion" events, Ais aids the Loki Familia in containing dungeon threats amid Antares-triggered monster rampages, though she remains peripheral to Bell and Artemis’s primary mission.

Additional facets include three confrontations with Phryne Jamil, a reincarnation lineage tied to Ariadne Lakrios (former queen of Lakrios), approximately 1,000 declined romantic proposals, and a preference for Jagamarukun. Her magic’s name "Ariel" references an air spirit from Shakespeare’s "The Tempest."
