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!
But all of them are said to boss-level!
!كما يُقال أنّها كلّها بمستوى زعيم
Und sie sind alle auf Boss-Level.
Y todos son nivel Jefe.
Y todos son nivel Jefe.
Et ce sont tous
des monstres de haut niveau !
Inoltre si dice che siano tutti di livello boss!
Além de serem todos do nível
de chefes de masmorras!
Как докладывают, 
все они не ниже уровня босса!
