When I first read the summary of this light novel, I was worried that Suimei would be an extremely unlikable character. However, when I started reading the story, my worries were put to rest. While he does have some jerk moments, he is a surprisingly not a horrible character. The volume does go into some details into why he behaves in specific ways like the reason for not telling his friends that he's a magician. The side characters like Suimei's friends were okay. Reiji has a personality similar to the other light novel protagonists, and it was neat to see the differences between Reiji's and Suimei's personalities. Mizuki was a typical sweet girl and is a little underdeveloped compared to the rest of the cast. I admit I couldn't stand Felmenia at first, but later in the book, her personality began to grow on me. I hope to see more development for the rest of the cast.
I enjoyed reading about the differences between the magic systems between the worlds, and the techniques used by the characters. Fortunately, it wasn't too tedious to read, and there wasn't a lot of technobabble. The illustrations in this book were neat and helpful for me to understand some parts of the story.
Since I was reading the pre-pub version of the story on the J-Novel Club website, I encountered some typos in the text. Hopefully, those mistakes are corrected before the volume officially goes on sale.
