Mate I understand your issue but the only thing I consider mandatory are the ones that Oda writes down, what you consider mandatory is fan fiction, since the author itself has not stated it.
No. Those are storytelling rules. It's not just about One Piece. it's about good narration in general. To make an antagonist character join ANY group of ally... that antagonist must be prepared FIRST as a false adversaries : (helping the protagonist/distanciation from the main antagonist etc.)
This is mendatory, not because of me or because it's One Piece. It's mendatory because without that, the quality of the story DROPS.
Are you saying that Yamato is gonna stay to defend Waso to fullfill the dream her father had for her?
No. i'm saying that yamato will CHOOSE her own pass.
What you guys don't understand is that becoming a guardian of Wano
doesn't mean that Yamato is doing what her father wants.
Why ?
Because Kaido wanted Yamato to become the shogun in order for HIM to be in control and transform Wano into a chaos land.
But if Yamato chooses for herself to become the guardian of Wano, she will do the EXACT OPPOSITE of that.
By making Yamato do that, Oda will prove that Yamato is finally free. Free from the chains of her father's wishes and will. She will make wano a better place, FREE from her dad's shadow.
That's what true freedom is:
the freedom to choose.
No she was fighting on the side for Wano after the raid Wano doesn't in need for Yamato as a fighting power Momo
Yes it means exaactly that Yamato is a fighting power. A guardian deity.
where did it show that she will stay in Wano
BNy the shadowings revolving around Yamato : Fighting for Wano / Helping Momo / Wanting to die for wano and Momo / stayin on the side of Momo. etc.
