Artbaran Henning is a magician and a member of the Demon Generals who appears in the light novel and anime series Let This Grieving Soul Retire!. Physically, Artbaran has short blue hair and striking blue eyes, with a smooth face and an overall cool, handsome appearance that is often described as androgynous. This look frequently leads others to mistake her for a handsome young man, though she is clearly established as a female character. Her attire is notably simple, as she does not wear armor or carry visible weapons, giving her the appearance of an ordinary civilian rather than a seasoned treasure hunter.

In terms of personality, Artbaran is generally collected, genuine, and gentle, projecting a cool, amicable, and charismatic aura. However, this composed exterior belies a more vulnerable side. She has a strong, almost fan-like admiration for the treasure hunter Krai Andrey, whose exploits as "Thousand Tricks" inspired her to pursue her own path. Her attitude toward Krai is one of deep respect and idolization, similar to that of another character, Chloe Welter. This admiration becomes evident when she becomes flustered or embarrassed, particularly when Krai calls her by the nickname "Arun," a name he adopts from her close friend, Mary Auden.

Artbaran's background is rooted in her early life as an ordinary child who was inspired to become a treasure hunter after hearing about Krai Andrey's impressive track record. She is the childhood friend of Mary Auden, and both are members of the treasure hunter clan known as the Hidden Curse. Her history with Krai is complicated by an unbalanced relationship; while she holds fond memories of a past encounter with him, Krai has no recollection of their meeting, a fact that adds a bittersweet and slightly comedic element to their dynamic. At one point, she and Mary sent a letter to Krai seeking an audience, during which she implored him to withdraw from a mission to destroy remnants of the Akashic Tower, a request he accepted despite not understanding the situation.

Her role in the story is primarily as a supporting character tied to the magical and technological side of the world. She is a member of the Demon Generals, a notable group, and tends to appear whenever the narrative involves magical equipment or armaments. Her first appearance is in the fourth volume of the light novel series, and from that point on, she continues to be featured in scenes dealing with magic gear, even when not taking center stage. Her key relationships include her friendship with Mary Auden, who affectionately calls her "Arun," and her one-sided, admiration-based connection with Krai Andrey, which serves as a primary motivation for many of her actions. As a magus treasure hunter, her notable abilities are rooted in magic, though her specific combat style and the details of her power as a Demon General are not extensively detailed, with her official party affiliation remaining unknown. Her character development is centered on her growing presence and connection to Krai, as her past with him and her status as one of his devoted "normal fans" are gradually revealed.
