Four points with I noticed in this chapter:
1. Even though Kanjuro had a large head start he didn´t show up yet or even warn the beast pirates, what happen?
Shouldn´t he already telling the beast pirates about the attack, yet they don´t know everything? Or did it is a trap to lure the strawhats and the alliance and waiting for the perfect time? Or is Kanjuro a fake traitor who mission was to "working" under Orochi only to betray him later? I don´t really know but I look forward for some twists...
2.Nekomamushi is still not in Onigashima, why? He already meet Marco two weeks ago, he should be right now with the alliance too!!
But for some reason he didn´t show up their, I can feel a plot around Neko for soon/later, could even see that Weevil has something do with Neko don´t beeing in Onigashima. Im still sure that Weevil need get defeated before Kaido, so something after the raid fails(in my opinion) should happen soon.
3.
Red: Onigashima Castle
Blue: Huge Sword
Green: Probably the Sunny or a regular ship
How large is this sword pls? It is almost big as a mountain. And im sure someone use that large sword in a battle.
My theory, the Skull was indeed a huge island size Oni from the past who get slayed and get killed in Onigashima(samurai vs Onis for later plotreason) and I wouldn´t be surprise if it was Ryuma who perform such a huge feat with killing the Island size Oni. Hope we learn more about Onigashima skull and the sword.
4. Flying six fighters
Green: Who´s Who
Blue: Sasaki
Red: Ulti
Purple: xDrake
Light Blue: Black Marie
Brown: Pageone
Based on this chapter we actually see the shoes of the flying six fighters. In the last chapter we see on the front Who´s who,Ulti and Sasaki while xDrake,BlackMarie and Pageone where behind them. People though the next to Sasaki was Black Marie, but it was Ulti.
Wouldn´t be surprise if these three leading the troup overall. For Black Marie, if we look closer we can see that she was at least larger then the other users.
Overall the chapter was amazing, I already feel the tension for the big war to start. The Flying six will play a big role, I try to understand yet the part of the Big mom pirates. Im feeling like Kaido don´t letting them fighting with them or at least they join the battle more later. Overall I place the Flying six right after the Calamity if we count the fact that they indeed speaking about the role of Queen if he dies and someone of the 6 gonna became the next calamity.
