Tohru, Yan, and Emel have at long last located Shiro’s spellbook, but it’s in the hands of the worst person imaginable: Adil, the corrupt captain of the Spellbook Library’s specialized sealing unit. But Adil isn’t working alone. He’s unleashed the first spellbeast—the spellbeast from which all others were created—and it’s on a mission to regain its original power: by bringing the Spellbook Library to the ground. Will Tohru, Yan, and Emel be able to reclaim Shiro’s spellbook and stop Adil and the first spellbeast once and for all, or will the Spellbook Library fall at the hands of the spellbeasts it holds?
