I just think it can all be achieved in ~16-17 pages. Let's say:
- 1 page for cover story
- 3-4 pages for Hiyori/Orochi. I can see Denjiro coming in and cutting him down. Though still, that might not be the end of him. I really think Momo (in human form) will cut him down with Ame after everything is over.
- ~4 pages for Kaido's final attack (transformation, dialogue, then double spread for impact)
- Followed by ~3-4 pages for Momo to move Onigashima with resolve.
- Ending with 2 double spreads from Luffy punching Kaido and Wano seeing the impact
Ofc it won't happen like this, but this is just what my brain is thinking atm lol. But yeah, I'm mostly convinced this is the end. Onigashima falling seems to be very symbolic to Kaido losing completely. I also think it's just time for it now. Before I thought maybe ~1050 was appropriate, but it happening a bit earlier is also good.
