Not sure how to feel about this.
I'm getting too used to seeing Isekai stories speedrun the setup that now this feels a bit too slow, a bit too padded.
It's also probably because we got a bit of a reverse order. If the majority of the content of this chapter was in chapter 1, and the duel was in chapter 2, then it probably wouldn't feel so weird.
I mean what kind of setup is this? Chapter 2 and most of the chapter is a flashback to what was resolved in chapter 1? It feels like a weird pacing break to decelerate.
