As a Sanji fan I have to say this was a good chapter for Zoro.
I really liked how he got his power-up thanks to a flashback and thanks to him understanding things, there was a possible scenario where Enma could have gave him a power-up for the music and that would have been so humiliating for Zoro, glad It didn't happen.
The flashback itself kinda cute, at least It gives something more for Zoro's character, which was flat for all the post time-skip.
Lion Song confirmed as one of his strongest moves, interesting how King didn't get single scratch.
Zoro's CoC haki design looks cool.
Overall good chapter, but of course Zorotars have to say bullshit like "Luffy Is Zoro's best friend" when It was clear he was refering to Kuina and "Queen said King is invincible" when he was talking about his race being capable of surviving every environmental, King isn't the strongest of his race, nothing suggests It and don't make assumptions, also the fact that Queen talks this much about lunarians probably means Sanji has that race genes, I mean King did a diable jambe this chapter.
So when Sanji will unlock King abilities do not say stuff like "Sanji Is the weak version of King" bullshit, since the Cook Is also human and also has other abilities and Zeff fighting style, if Sanji has his genes It would actually been that he will most likely be stronger than King by the end of the arc.
