Its a hard read.  The fight scenes go on forever and so much dialogue and descriptions just keep dragging onnn. I usually love those kinds of books but this was just painful to get through.  Writings pretty okay so im guessing the author just never read it all at once. The vn does an amazing job with its characters though. If you "push through it" it has its enjoyable parts. My recc is just skim through parts that drag on, chances is it has no relavence to the plot.
Also really wish the author just finished the main story before working on his side one. Takes out the immersion of the world and kept the viewers waiting for something thats now extreamly out of reach.  Also has bugs that author has no interest in fixing. Aside from the use of AI backrounds, cool art though.
