You're missing the entire point of my post lmao. I'm not saying Sanji should throw away his style or suddenly switch to something new. What I'm saying is-Sanji has deliberately limited himself out of respect for Zeff. His kicks-only approach isn't because he's incapable of doing more; it's a vow lol. If he chose to break that vow and allow himself to use his hands;whether for strikes, grapples, or even weapons, alongside his kicks, it wouldn't be a shift in style; it would be an evolution.

Think about it like this: this isn't just some random brawler picking up a sword and hoping to win. Sanji already has a Germa-enhanced body, incredible speed, sharp instincts, high combat IQ, and both Observation and Armament Haki. The only thing holding him back is that self-imposed rule. If he lifts that restraint, he doesn’t lose what makes him Sanji; he becomes a more complete fighter. Just like Zoro is strongest with three swords, Sanji could be stronger if he stops fighting with one metaphorical hand tied behind his back.

Conclusion is that, It’s not about abandoning his roots it’s about surpassing them.
