In a world where magic is not a fairy tale but an everyday reality, its use is strictly regulated by a powerful governing body known as the Magic Tribunal. Seventeen-year-old Cecile is a trainee at a law firm who works as a defense attorney for magical beings, navigating complex legal situations, dealing with extravagant clients, and challenging a rigid judicial system that oversees those with paranormal abilities.

The story follows Cecile as she confronts a particularly difficult case that forces her to grapple with universal themes of isolation, fantasy, and self-confrontation in contemporary society. As she journeys through the intricacies of magical law and her own personal struggles, she undergoes an emotional transformation toward personal liberation. The film combines elements of fantasy with a grounded, emotional atmosphere, depicting how Cecile must balance her professional responsibilities with the surreal circumstances of defending clients who possess extraordinary powers.

The central protagonist is Cecile, a seventeen-year-old legal trainee whose work brings her face to face with the strange intersection of jurisprudence and sorcery. The Magic Tribunal serves as the primary antagonistic force, a bureaucratic entity that limits and controls magical activity through endless litigation and enforcement. The setting is a contemporary Japan where supernatural abilities are commonplace yet strictly policed, creating a society where charmers and sorcerers must answer to human laws.

Notable narrative arcs include Cecile's development from a tentative trainee into a confident advocate, her exploration of how magic and justice can coexist, and her personal journey toward understanding her own place in a world that seeks to control the extraordinary. The film is directed by Takeru Shinozuka in his commercial directorial debut, produced by Yoshihide Moriyama, and released by Toei Animation under their ETERNA Animation brand, with a scheduled release in 2026.
