Mirellia Q'Melromarc

Your Duty and Political Role
To rule Melromarc with an iron fist: As a matriarchal kingdom, supreme authority rests entirely with her. Her husband, Aultcray XXX (the Hero of the Staff), holds the title of king consort but lacks the final say in matters of state.
Global diplomacy and war containment: During the beginning of the story, Mirellia was traveling the continent to calm international tensions caused by the illegal summoning of the Four Holy Heroes in Melromarc.
Restoring the Shield Hero's Reputation: Upon returning, he undoes the false accusations against Naofumi, severely punishes Aultcray and Malty (renaming them "Trash" and "Bitch"), and restores the resources and influence that belonged to the Shield Hero.
Coordinate the defense against the Waves of Calamity: Organize logistics between kingdoms, convene international conferences, and manage strategic alliances to ensure the survival of the world.

Dislikes
Religious fanaticism: He abhors the extremism of the Church of the Three Heroes and its systematic discrimination against the Shield Hero and demi-humans.
Incompetence and selfishness in politics: He despises impulsive actions that jeopardize the security of the kingdom.
The ruthless acts of her eldest daughter (Malty/Bitch) and her husband (Aultcray/Trash): She feels deep pain and indignation at the conspiracies and abuse of power committed by her family in her absence.

World peace and geopolitical balance: He dedicates all his efforts to maintaining stability between the realms of men and demi-humans (such as Siltvelt and Shieldfreeden).
Justice and a sense of duty: Value fairness above blood ties.
The Shadows (Shadows of Melromarc / Kage): He fully trusts his secret network of espionage and intelligence.
The Shield Hero (Naofumi): Feels a deep professional respect and gratitude towards Naofumi Iwatani for his prudence and effectiveness in the face of the threat of the Waves.
His daughter Melty: He fully trusts her for the future of the throne.
The Filolial: She admires both the Filolial and the Filolial queen Fitoria
