This light novel series's author has done a better job writing and developing the cast than the author of the main series. The story develops and gives minor characters more page time, and shows more of their personality and hobbies. Even though the series is full of short stories, there are actual stakes and character development. It also contains some scenes that didn't make it to the main series, and those scenes are really comedic. It's worth reading since it can show the chill adventures side of the characters than the full on brawl version of the characters in the main series.
