The Hero and the Sage, Reincarnated and Engaged: Volume 3

Raid and Eluria’s clash with Lufus Lailas and her Guardian Dragons reaches an eventful and ominous end as pieces of the puzzle finally come together and lead them closer to the “mastermind” they have been seeking all this time. With the long-awaited integrated exam right around the corner, students of the Vegalta Royal Institute of Magic turn eastward to sparkling waters and new adventures...while the Hero and the Sage turn to desolate lands and ancient ruins in search of answers long buried beneath the sand. They’re joined by an odd duo of special-class magicians from across the sea who carry their own set of curious circumstances. And thanks to an unexpected slipup from none other than the Hero himself, the eastern region turns out to be a land full of new developments and shocking discoveries for the most powerful couple in the world!
