Movie
Description
Mira Yamana, also known as Amano Kagami, served as Head of Grimoire Security and the Trinity Seven for the Superbia Archive at Royal Biblia Academy. Initially withdrawn and fearful of losing control of her immense magical power, she isolated herself despite Lilith's efforts. Akio's active outreach inspired her to embrace her abilities and pursue justice, forging her serious and duty-driven nature.

Her early responsibilities involved eliminating perceived impurities and threats like Breakdown Phenomena, leading to initial hostility towards Arata Kasuga due to his Demon Lord potential. Investigating Liber Academy's disappearance, however, fostered acceptance of Arata as an ally and friend, revealing her underlying kindness and capacity for growth. Mira balances a stern, justice-focused exterior with a pure and easily flustered core, particularly regarding impure situations; deprivation of clothing or magic reverts her to her original timid self. Interactions with Arata and others gradually softened her rigidity, allowing her to express care more openly.

In combat, Mira mastered the Thema Justitia and the magic Gehenna Scope. Using her grimoire, the Book of the Mirrored Lands, she could analyze, reflect, and neutralize opposing spells. She demonstrated tactical ingenuity, predicting opponents' moves and exploiting weaknesses, though her purity initially made her vulnerable to perverse tactics. These skills established her as one of the Trinity Seven's most formidable members, capable of defeating adversaries like the Paladin Arsha. Later, she transitioned into a Hero Candidate, enduring brutal training with Ayesha involving repeated deaths to master instant revival—a core Hero ability for combating threats like Demon Lords. This path required relinquishing her Trinity Seven status and Superbia Archive.

Upon becoming a True Hero and Arbitrator of Justice, Mira gained angelic wings and a new Thema embodying absolute justice, wielding powers capable of destroying gods and demons. This transformation separated her body and soul, aligning her with the cardinal virtue of Justice. Prioritizing missions above all, she retained enough self-awareness for polite interactions with former allies. Her resolve fractured battling Titaness; she confessed hatred for the constraints of her "Justice," discarded her Arbitrator powers to reclaim her identity and Superbia Archive, and reverted to the Trinity Seven with a new appearance.

Physically slender with long blonde hair often tied by a red ribbon, Mira stands 152 cm tall. Exhausting her magic in one battle deteriorated her vision, requiring glasses. She typically wore the Royal Biblia Academy uniform, adding a white cape in Magus Mode. Post-Arbitrator, her look evolved to include braided hair and eventually a new outfit after rejecting the Hero path.
