Grimoire of the Rift is the sequel to Final Fantasy Tactics Advance as well as an iteration in the Ivalice Alliance. It is set in the same world of Ivalice of Final Fantasy XII, and follows the adventures of a young boy transported to this world by a magic book, who encounters many monsters, and a sinister plot to unleash something from another dimension.

Return to Ivalice in the latest installment of the legendary FINAL FANTASY TACTICS series. Summer vacation has begun for all but one unlucky student. Alone in the school library, Luso solemnly toils away the punishment his mischief has brought him. It is there that he finds a dusty, mysterious book. Opening it, he reads aloud the only text it contains: “One is fated to fill these barren pages. Know you his name?” Scrawling his name onto the next blank page, Luso unwittingly begins the first chapter of an adventure all his own.
