My quote back in Wano being relevant again regarding Kuma mentioning "Nika":
"Wano has been nothing short of false hype. Countless subplots that have yet to be answered and yet here goes Oda continuing to add more subplots to the story without even addressing any of the past subplots. False hype after false hype. Nothing annoyed me more than Kaido mentioning Joy Boy because I know that was straight up a fan service dialogue to make the fandom think it is something important.
Let me give advice to the fandom, if Oda continues to mention important concepts without elaborating or addressing them, then that is the definition of false hype and fan service."
