I really like how there hasn't been any "asspull" yet. Like, everything that have been happening has been already foreshadowed on previous chapters, mostly in this "battle" arc. Like the fact that even if Stark is kinda coward he is powerful (but he still hasn't realized this yet, and probably never will), or Fren being trained to purposely being strong against demons or even Frieren hiding her true mana aura (yeah, it was already hinted on chapter 18 that Frieren was strong against Aura's scales) I love how the author briefly shows information through little panels or even a single phrase to let us theorize just to confirm it the following chapters.
