How Not To Summon A Demon Lord Vol 19

Great opening for this volume. Diablo having to learn a new class in order to survive his new stronger enemies is totally worth reading through. He would have to go through those training arc that every other shounen manga would have to go through if the author did not try to skip so much of the training the sword master teaches. Understandable, it just the feelings of achievement fell off when it is rushed, like a sudden power up without a step-by-step process. It is still understandable though as it does save time from a really long arc. Now, it seems that Diablo is going to have his first trial run with his warrior class.
