Konosuba

I admit I rounded up to 5 stars because of the anime. Some of the scenes were funnier because I'd watched them. (If you haven't seen the anime, I highly recommend it.)

If you like fantasy and comedy, I think you'll like this book. If you like RPGs, I think you'll like it even more. The only down side for me was the masochist character, which I didn't find funny, but it didn't ruin my enjoyment of the story.
