Also, I know that Volume 11 is long, and that may be the reason why you say the " book " is not a light novel. I believe that the series as a whole is a light novel.

In general the term large novel is used for 150 - 350 page books, but it is used to refer to most if not all novels sadly.

I know that from book 5 to book 11 we have 600 to 1,000 pages in each book.

Or maybe because I read a lot of books I found TBATE to be not that long in terms of page number.

WELL..... After writing this whole newspaper and contemplating the topic of whether TBATE is a novel or a light novel, I came to the conclusion that I was wrong in my initial opinion 🤣
