It’s the Daihasei Festival, and everyone’s parents are in town! As Toma and Mikoto compete against each other in various events, a Roman Orthodox magician and her assistant negotiate to purchase a powerful relic from the English Puritan Church.

As Toma and his group try to track down Oriana, they discover that a “Shorthand”—a specialized spell that operates on its own once being cast—is shorting out their magic. But before they can deactivate it, an incident happens at the middle school.

With the Shorthand cancelled, Stiyl uses his magic to locate Oriana, causing a fight to erupt. In London, Laura learns that Oriana’s deal might not be for the Stab Sword, but for something else entirely.

Tsuchimikado’s location spell backfires and leads Oriana straight to him, resulting an epic showdown. But he’s not the only one exposed to Oriana’s magic: Himegami feels the force of the spell caster’s power, and may not survive.

Toma and Tsuchimikado investigate the history of a sacred artifact as they try to figure out what Oriana’s plan is. When they discover they have only until nightfall to stop her from enacting an evil plot, the battle for the future of Academy City begins!

As Toma and the others come close to beating Oriana, the motivations behind her actions are finally revealed. But taking out Oriana might not be enough to stop her plot from reaching a catastrophic completion!
