I wasn't too happy watching a paper bird survive having fireballs thrown at it for 19 pages (the entirety of chapter 4 and the last handful of pages of chapter 3).
I think the point of chapter 4 was to establish the temperament of the bad guy, but it didn't do that very well. I wasted my time reading chapter 4, and I'm sorry to the translation team who had to waste their time translating it.
Edit: Chapter 5 was just released. The entire chapter was the same as chapter 4. This brings us to about 35 consecutive pages spread across 3 chapters where it's nothing but a bad guy trying to destroy a paper bird that was accidentally created by the MC on a whim. Maybe the bird and the bad guy are important later in the story. As of chapter 5, neither the bird nor the bad guy are established characters, so I have no reason to care about them, let alone care about them for nearly 3 whole chapters.
