The term grand magic was used to refer to Angel Fall alone, up until Tsuchimikado Motoharu's explanation to Kamijou Touma regarding the use of Feng shui by Kamijou Touya to arrange the souvenirs and charms in his home to create a magic circle. Here, Motoharu states the danger of moving or touching the souvenirs as would create an entirely new magic circle, therefore a new spell.
Motoharu lists examples, and all refer to them in as Grand Magic:
- Earth Shaker (
極大地震Kyokudai Jishin (Āsu Sheikā)?, lit. "Maximum Earthquake")
- Phantom Hound (
異界反転Ikai Hanten (Fantomu Haundo)?, lit. "Underworld Reversal")
- Cocytus Replica (
永久凍土Eikyūtōdo (Kokyūtosu Repurika)?, lit. "Permafrost")
- The 2nd Toaru Majutsu no Index Soundtrack for the second season of the anime adaptation has the Dai Majutsu as the 7th track. Although none of the spells referred above are mentioned above, it most likely refers to the large-scale spell La Regina del Mare Adriatico.
