Iska Bra is a character introduced in the fourth season of the anime, specifically appearing in flashbacks that depict past events in the city of Orario. She was a member of the Astrea Familia, a group of adventurers known for their strong sense of justice and their close relationship with the elf Ryuu Lion. Iska was an Amazoness, recognizable by her dark, tanned skin and black hair, which she typically pulled back and styled into a braid. Unlike many others of her race who often prefer more revealing attire, Iska had a unique sense of fashion and would choose outfits that were comparatively more modest, alongside a noticeable use of makeup and cosmetics on her cheeks, lips, and nails.

In terms of personality, Iska was considered the most feminine member of her familia and was deeply passionate about fashion and beauty care. This enthusiasm was not merely superficial; it stemmed from a difficult past. As an orphan living on Daedalus Street, she pushed herself mercilessly as an adventurer to support her orphanage, to the point of severely neglecting her own health. After realizing the terrible state of her mind and body, she developed a profound interest in beauty care as a means of recovery. The positive reactions she received when first trying makeup fascinated her, leading to her characteristic dedication to the craft. She believed that by making herself beautiful, she could also bring beauty to her surroundings. When Ryuu asked if being beautiful was her form of justice, Iska happily agreed, preferring this straightforward and uplifting ideal over dwelling on complicated matters beyond her control. She was known to be quite persistent when discussing fashion and would spend hours applying makeup, sometimes holding a large mirror for over two and a half hours without stopping. Despite her talkative and expressive nature, she was a responsible member of her familia and disliked it when others pitied her.

Her role in the story is tied directly to the tragic history of the Astrea Familia. Five years before the main timeline, the familia was nearly wiped out. Iska was among the members who perished during this incident, killed by a powerful monstrous creature known as the Juggernaut, which had been accidentally summoned by another group of adventurers. Her death, along with that of her comrades, is a significant part of Ryuu Lion's traumatic past, and the flashbacks in the fourth season serve to illustrate the bonds Ryuu lost and the weight of her quest for vengeance.

Regarding key relationships, her most significant connection was with her goddess, Astrea, and her fellow familia members, particularly Alise Lovell, Kaguya Gojiono, and Ryuu Lion. Her interactions with Ryuu were notable for her persistent efforts to recommend stylish combat outfits to the elf, often overwhelming her with enthusiasm. As a member of the Astrea Familia, she worked closely with her comrades in their mission to bring justice to the city's slums. In terms of development, Iska’s personal journey was one of transformation from a self-sacrificing orphan who destroyed her own health to a young woman who found purpose and joy in self-care and beauty. She managed to rank up several times at a fast pace, achieving her final rank up at the age of sixteen after participating in the Great Feud, a major conflict against the powerful adventurer Alfia.

In terms of notable abilities, Iska was a second-class adventurer, meaning her physical prowess was exponentially superior to normal people or lower-level adventurers. Her physical strength was particularly impressive. She was a skilled combatant who fought using a boxing style, capable of operating effectively in both the vanguard and middle guard positions. She also possessed a magic spell that launched a two-fist attack, though the specifics of this magic remain unknown. Aside from her combat skills, her most distinctive talent was as a makeup artist, where she was considered the best in her entire familia.
