This chapter is the end of vol 103 right?
I guess next chapter may start Kaidou's flashback since the end should be a cliffhanger + the beginning of a new vol...
Unless i'm wrong and it's next chapter the ending of this vol to which i would say the same, next chapter may start Kaidou's flashback
OP volumes these days are rarely more than 10 chapters so this should be the last chapter of vol 103. That being said, it highly depends on the next chapter. It could be extended if Kaido is meant to lose already, though I doubt this.
I've looked at patterns for past villains and many of them lose like 4-6 chapters in the following volume after Oda starts focusing fully on Luffys fight the volume before.
- Crocodile and Enel's last ~ 3-4 chapters into vol 23 and 30 respectively.
- Lucci lasts like 8 chapters into vol 44, so pretty derivative.
- Doflaingo lasts ~5 chapters into volume 79
- Katakuri lasts ~6 chapters into volume 89
- Lesser villains are similar, some a little shorter or 3-4 chapters in a new volume
Not really a pattern per se, but if it's something that's being adhered to for volume structure, I can see Kaido being defeated about halfway into volume 104, or around ch 1049-1051 is my guess.
