I cannot help but think IJ would have been a good power up if it were to be developed during the TS. IJ being a stronger DJ would have been fine then.
Now it is just underwhelming. CL²²Oda is spamming it at any given occasion to show Sanji has grown stronger and has a new mode. Whether he hasn't realised they look identical (and equally bad as a PU) or he is purposely shitting on our boy, something he particularly enjoy apparently, is a mystery. I hate him
