Mira Dianus Artemina is the former Queen of Artemyra from the world of Magi. She is a powerful Dungeon Capturer who conquered the 24th Dungeon and obtained the Djinn Cerberus, making her a formidable magician and warrior.

Mira is a beautiful woman with long, straight blonde hair reaching her ankles, striking pink eyes, and a distinctive tattoo on her right cheek. She typically wears an elaborate Artemyran outfit, complete with a crown-like helmet, feathered collar, jewelry, and decorative armor. Her Metal Vessel takes the form of a spear.

Her Djinn, Cerberus, grants her control over three elements: heat, ice, and lightning. She is an exceptionally capable fighter who combines magical power with her spear skills.

Mira is the mother of Pisti and several other daughters, whom she deeply cares for. Although she is no longer Artemyra's reigning queen, she remains an influential and respected figure with considerable political authority.

Despite her royal status, Mira is independent, outspoken, and unwilling to let anyone dictate how she should live.
