Now that i read the french version of the chapter(lucky me that i can speak/read french
), it's pretty clear the portrayal was around the fact that
- Kaido was fearing Wano's military's power
- Used the 5years timespan to reduce Oden's military power while increasing his own
- Oden only had his 11 scabbards vs Kaido's army
- The hostage tactic was part of Kaido's plan and Oden was even stronger than Kaido expected, with Oden almost beating Kaido if not for the hostage moment
The ending is predictable as well, with Oden managing to save the scabbards while boiling alone
