I have to note it actually fits for sanjis opponent to have zoro connections (also king had sanji connections)
given how Zoro and sanji are rivals
I mean I suppose but like these connections in particular are more like puns of foreshadowing rather than what can be used in a meaningful way if that makes sense. Like sommers connections to sanji you can sorta see why oda has them. Hes an inverse of zoro to fight with and that can develop his views on passion and defends sanjis honor like okay I see that
But putting many, and I mean many puns on killingham to zoro isnt rlly smth that can help sanji grow. It feels more like a miss match to me personally. Unless we get smth with zoro and killingham (a death pack zoro mma is perfect for this)
