Description
Juna Doma, granddaughter of Excel Walter, emerged during Kazuya Souma's talent search by winning the Elfrieden Pretty Girl Grand Prix. She displayed extraordinary vocal talent, memorizing songs after minimal exposure. Her voice became central to the Jewel Voice Broadcast and Project Lorelei, earning her the title Prima Lorelei as she supported cultural and educational programming. Initially deployed as the spy 'Canaria' by her grandmother to evaluate Kazuya's fitness as king, she abandoned her mission upon witnessing his effective governance. She revealed her true purpose and pledged loyalty, prompting Excel Walter's formal allegiance before the Final Counsel.

Commanding the Marine Corps during the One Week War, Juna stalled the Amidonian Army's advance and inflicted substantial casualties, demonstrating covert operations expertise. Over time, she developed romantic feelings for Kazuya, comforting him with lullabies during overwork and resolving to support his vulnerabilities while Liscia bolstered his strengths. Excel proposed Juna as a secondary queen consort; Kazuya deferred a public engagement until other Lorelei singers could replace her irreplaceable broadcast role. They entered a secret betrothal, with Juna gradually reducing primary broadcast duties, though she occasionally hosted programs like *Singing with Big Sis*.

Juna married Kazuya at his coronation, adopting the surname Souma and becoming the First Secondary Queen Consort. She later served as acting head of state during a military expedition while Liscia was pregnant and other consorts were absent. She retrieved Excel from Lastania using a love letter as leverage and joined the Friedonian expedition to the Duchy of Chima, where her presence deterred unwanted marriage proposals to Kazuya. On a covert mission to the Nine Headed Dragon Archipelago, she assisted disaster relief by compiling monster reports and used her singing to coordinate naval forces, enhancing combat cohesion. During this mission, she revealed her pregnancy to Kazuya, later giving birth before the Lastanian refugees arrived in Friedonia.

Juna maintained ongoing duties in state affairs and cultural programs, balancing her roles as consort, mother, and public figure. Her abilities included water-based magical combat enhancements, such as imbuing throwing knives to pulverize projectiles, and leadership in marine operations.
