quite an amount to take away from this chapter
no order but heres what I took
1) So jack is ruler of Kuri, guess that means regions of Wano are each calamity owned,
which means That we are looking at this arc progressing in a way in this format
defeat calamity of each region ---> proceed to liberate Wano ---> possibly Kaido comes out and begins the main antagonist fight, maybe.
2) that Shutenmaru(which going by his name is Likely a Youkai) is located at a place called Mt.Atama(going by translation of the name, plus i think im spelling it wrong. Point is theres a mountain. lol)
3) Holdems powers as well as another possible grade/special sword in that "Chasing Sword Karakuri Sword"(though we didnt see its powers )
Holdems powers are interesting, has a lion entity(obviously from his fruit) but where he learned fire breathing?
imo its possible given how long Kaido has been there maybe he learned it from Ninjutsu
. he already has a special sword thats prolly from Wano, maybe he picked up some techniques while being there to from the ninjas who work for Kaido (if they do).
