This panel just confirms that Joyboy=Ryuma.
Both were equals.
Ryuma hype is Zoro hype.
Ryuuma defended Wano from THE WG entirely and solo too. Imo definitely worthy of being equal to the hero warrior god whatever of liberation himself too.
God of freedom/liberation Nika Joyboy.
Sword God Ryuuma.
Luffy and Zoro are the modern day reincarnations/successors/proteges/inheritors/whatever of that.
Ryuuma being Joyboys VC if possible would be awesome. I have a feeling Tokis fruit has history with Ryuuma somehow. That somehow he could have been sent centuries into the future if Ryuuma is really centuries later after Joyboy. I'm too confused on the OP timeline and history lol.
I'm sure Oda must be a fan of Samurai Jack somehow especially post Wano too lol.
