Eshune is the daughter of Enome, a receptionist at the local guild. She possesses blue eyes and blonde hair cut to chin length, styled with three hairpins on her head's right side forming a winking face emoji. Her petite, slender frame is notably well-endowed, and she typically wears a uniform matching her mother's.

Eshune deeply adores Enome but harbors deep resentment toward her biological father, Zenith, who abandoned the family just before her birth for an affair. She explicitly considers him dead and maintains no filial respect, despite later learning he is a god. Her primary motivation is orchestrating a relationship between Enome and the skilled hunter Kikuru Madan, intending him to become her stepfather. She actively facilitates their interactions, believing Kikuru's reliability and strength make him the ideal replacement. Her efforts include referring to Kikuru as "dad" and persistently encouraging his union with Enome, though Enome dismisses the idea. Eshune perceives Hanabata Nohkins as the primary obstacle, viewing Hanabata's physical attributes as giving her a competitive edge for Kikuru's affection.

During a confrontation, Zenith reveals to Eshune that she was conceived as part of a specific plan, emphasizing her importance to him, but declares their meeting their last and divorces Enome. Eshune concurs with the separation, urging both Zenith and Enome to pursue their own happiness.

Kikuru initially misinterprets Eshune's affectionate gestures as romantic interest, but she clarifies she sees him only as a potential stepfather. She assists Enome with guild duties, reflecting their close relationship, though she typically addresses her mother by name rather than "mom".
