How Not To Summon A Demon Lord Vol 21

Once again, a blasting moment as the war wages in between both the races and the fallens. Multiple have either fallen or out of commission as the strong slowly start taking the front row. A quick and decisive battle ensue as the top of the food chain between both race appears for the victory.

So, this long awated war just flew by with just two volume. I would thought it go for longer or more like drag it out a bit. I guess the author is being rush or something because this volume alone already reach the climax of the war. There, I thought it be a grueling battle as both side causes seriuus damages to each other. Then, it would go until the Diablo comes back and start a fight to reach the Demon Overlord. This feels rushed and seems like it might not get a good conclusion or a good flow for the conclusion of this series.
