I am not talking about this aspect.
This series literally has talking fishes, I know this.
What's not realistic is Gorosei and Imu allowing one Commander level guy to escape after a fodder protects him from an attack
Sabo and Cobra should be dead together. I know Sabo won't die cause he's under plot armor but still.
It's a bad look for them.
Also Wapol escaping and Vivi tagging along next to a bunch of trained assassin killers who have Haki and speed.
