Barnabus, the mage known as the “Transcendent”, comes to Wimberg Kingdom. He is also the principal of the Barbador Magic Academy that Kannazuki and the others attended. Barnabus claims that a problem has arisen with the arrival of heroes from another world. Then an urgent messenger appears with news that a large horde of monsters has appeared in the woods near the kingdom.

Holding them off are the Valkyries, the adventurer’s guild, Saria, and the others! A great, fast-paced battle against monsters is about to begin!
Yeah, it's a promise!

Claro. Te lo prometo.
