I think sandai will broken in this arc. Then it will replaced by shusuui or idai, i believe nasjuro holding the idai and after this arc maybe SHP will going back to wano for repairing the "smile" Effect and take shusuui back after they know who saved the country. Then for the last buff zoro at least will make wado black and i hope 2 more sword will get blackened too.
- I feel like zoro and shusui are just done. With it likely being fate zoro one of Ryuma’s decedents brought it back to wano
- Lowkey idk exactly how but I do think the scarred eyes both ryuma and zoro have might be tied to shusui somehow
- As for nusjuro I doubt he goes down this arc and with him likely playing a role post egghead it’s unlikely he gives up his weapon. Even if he does have shodai
