I, Type-Moon, the Manga Artist!

The male lead is 1.9 Meters tall, but this is barely shown in the plot. Later on, I subconsciously perceive him as a cunning and scheming man. His combat relies mainly on shouting out skill names. I've watched about 20% so far, and the protagonist's image keeps changing. Some characters' roles are completely unclear. For example, the priest on the train—he appears in only a few chapters, and all we know is that his entire family was ganked by a traitor; nothing else is known. He seems like a background character, yet he keeps appearing in those few chapters. There's also the Great Escape Sand Dune. After thinking about it for a long time, I've come to the conclusion that its purpose is to turn the male protagonist into a super/special forces soldier without any pressure. There's also the part about going to the dream world wearing a mask, and then encountering a bunch of people. What? You say you're 5 good and 5 evil, but with the mask you're 4 good and 6 evil, and then you just put the mask on and take it off and start having fun with everyone. Anyway, your book has a lot of confusing plot points. I don't mean to criticize you, I just simply don't understand why the plot is written this way.

What is this book about? Is it good?

I thought I had finished reading it all; I had subscribed to over 900 chapters.
