Description
Aura Bella Fiore is a Dark Elf and one of the two Floor Guardians responsible for the sixth floor of the Great Tomb of Nazarick, where she serves as the older twin sister of Mare Bello Fiore. She was created by the Supreme Being Bukubukuchagama, and her design and core personality traits are directly inherited from her creator. Despite her youthful appearance, which resembles a human child of about ten years old, Aura is actually seventy-six years old, an age considered to be in the early stages of development for a Dark Elf. Her physical characteristics include dark brown skin, long pointed ears, golden blonde hair cut at shoulder-blade length, and heterochromatic eyes, with her left eye being blue and her right eye green. Her typical attire is a tomboyish outfit consisting of reddish-black dragon scale leather armor covered by a white and gold vest embroidered with the guild emblem of Ainz Ooal Gown, along with white trousers and gold-plated shoes.

In terms of personality, Aura is known for being cheerful, energetic, and straightforward, often speaking her mind with a blunt and direct manner. She presents as a tomboy and prefers clothing that allows for easy movement, avoiding dresses or skirts. Her personality contrasts sharply with her twin brother Mare, who is timid and reserved; Aura is the dominant one in the relationship, frequently taking charge, dragging him along, and telling him what to do. Like all NPCs of Nazarick, she possesses an absolute and unwavering loyalty to the guild leader Ainz Ooal Gown, carrying out her duties with great zeal and being willing to sacrifice everything, including her own interests, for his sake. She holds a deep sense of longing for her absent creator, Bukubukuchagama, and treasures a watch given to her by Ainz that contains a recording of her creator's voice. While she often engages in small quarrels and arguments with Shalltear Bloodfallen, this relationship is not born of genuine animosity; rather, they are quite close, bickering like true sisters. Aura also has a strong collector's spirit when it comes to creatures, desiring to add any new and unfamiliar beast she encounters in the New World to her collection. However, this enthusiasm does not extend to insects, towards which she displays a notable fear and aversion.

Aura’s primary role within the story is as a key operational asset for Ainz, especially in outdoor and large-scale scenarios. Her responsibilities often involve reconnaissance, suppression of hostile territories, and the construction of forward bases. She is tasked with overseeing the Great Forest of Tob, building an emergency shelter there, and later, as the Sorcerer Kingdom expands, she is responsible for constructing and managing a vast surveillance network across the nation. Her skills are frequently called upon when Ainz requires knowledge of forests and magical beasts, and she actively supports his activities when he ventures outside under the alias of the adventurer Momon. Aura has a significant presence in several major events: she played a crucial role in the battle against the叛变 Shalltear by using her skills to create a distraction at a critical moment, allowing Ainz to cast his super-tier spell; during the expedition to the Dwarven Kingdom, she used the World Item Shan Hai Zu, a道具 that can trap targets in an alternate space, to imprison over eighty thousand Quagoa, enabling Shalltear to eliminate them; and she was also instrumental in securing magical items for Nazarick, demonstrating her combat prowess by defeating a former adamantite-ranked adventurer with a single arrow.

In terms of key relationships, her bond with her twin brother Mare is the most prominent. She acts as his protector and guide, a dynamic that reflects the relationship her creator had with her own younger brother. Her relationship with Ainz is one of absolute fealty, but due to her childlike demeanor and lack of romantic interest in him, Ainz tends to treat her with a softer, more paternalistic attitude compared to the often-overbearing affections of Albedo and Shalltear. This makes her a calming influence among the female Guardians, as she lacks the intense, possessive crush on Ainz that the others exhibit. Regarding her creator, Bukubukuchagama, Aura holds the highest level of respect and loyalty, followed by Ainz, and then her creator's younger brother, Peroroncino.

Aura's development throughout the series shows her growing into a more independent and responsible role as the Sorcerer Kingdom expands. She transitions from simply guarding her floor to managing complex logistical and military operations across a nation, showcasing her high social competence and reliability, which earns her a very high evaluation from Ainz. While she maintains her bright and innocent personality, the narrative also reveals the inherent cruelty of her nature as an NPC of Nazarick; she holds a neutral to evil karma value of -100 and can be casually ruthless towards those she considers enemies or inferior, viewing humans with a sense of superiority and as little more than curiosities or tools.

Aura’s notable abilities make her a formidable asset. In individual combat, she is considered one of the weaker Floor Guardians, but her true strength lies in her role as a high-level Beast Tamer. She possesses the ability to command and control hundreds of high-level magical beasts, with some of her strongest monsters reaching up to level 80. When enhanced by her special support skills, these beasts can fight at a level equivalent to 90, making her the strongest Guardian in group or large-scale battles. She has a diverse collection of creatures at her disposal, including神狩狼 Fenrir, Kirin, and other mythical beasts. Beyond taming, Aura is a master ranger and scout, boasting the highest agility among all the Floor Guardians. She is a specialist in guerrilla warfare and possesses numerous detection and tracking abilities. Her combat equipment includes a whip and a large, decorated bow, and she has skills such as one that binds an opponent by their own shadow. One of her signature skills involves exhaling a sweet-smelling breath that simultaneously grants buffs to her allies and debuffs her enemies over a wide area, an effect that can even influence targets resistant to mental attacks. She is also the wielder of the World Item Shan Hai Zu, a道具 that allows her to trap opponents in one of one hundred different alternate spaces, though it has the weakness that the owner can be transferred if the trapped target successfully escapes.
