OVA
Description
Natsuki Minamiya balances dual roles as an English instructor at Saikai Academy and a high-ranking attack mage titled the "Witch of the Void." Tasked with safeguarding a legendary magical prison housing supernatural criminals, her physical form remains perpetually sealed within its barrier. The persona interacting with the outside world manifests as an illusionary projection, fully sentient and autonomous. This existence defines her triple function as the prison’s "jailer, door, and key," sustained by an enchanted ten-year slumber that halts aging, leaving her trapped in a youthful guise despite her chronological adulthood.
Her history intertwines with the Akatsuki family following the Fairy’s Coffin incident, binding her to mentor Kojou Akatsuki, the Fourth Primogenitor. Their dynamic oscillates between clashes over his impulsive actions and an unspoken protective alliance, underscored by mutual respect. Kojou’s deliberate use of the "-chan" honorific needles her authority, reflecting their combative yet caring rapport.
In the Banquet for the Observers arc, Aya Tokoyogi’s theft of her memories and powers leaves her stranded near the Keystone Gate. Rescued by Asagi Aiba, she adopts the alias "Sana," residing with Asagi until consuming Kojou’s blood restores her identity. This act also awakens her guardian, Rain Gold—a golden-armored knight constrained by power-limiting seals to protect Itogami Island from destruction.
Her combat prowess spans spatial manipulation for teleportation and temporal leaps, conjured chains for offense, and sole mastery over the prison’s barrier. Enhanced agility and strategic acumen let her engage numerous foes, while her true adult form lies hidden within the prison’s confines.
Beneath a stern exterior lies compassion: she orchestrates a festival for Astarte’s emotional growth and quietly nurtures Kojou’s potential despite frequent exasperation. Her overarching aim—to bridge human and demon coexistence—anchors her philosophy, driving her efforts to harmonize the supernatural realm’s fractured factions.
