There's only so many directions you can trap yourself if the plot revolves the same device - in this case, you gotta hurt someone every time. Eh, but I enjoyed it for what it's worth, and I guess Nameless was able to translate and release so many chapters since they knew they were on the last volume. I'm glad they finish it, and hopefully that takes a load off them for a good while.
So apparently this is actually an adaptation to a web novel, and now I'm just curious where I could find the original source.
