Good chapter and I'm looking forward for the next chapters, post-arc parts are always my favorite parts of op.
About the fight in general and the ending, I've liked it. Kaidou has been fighting for more than 50 chapters, he suffered a lot of wounds and has been shown tired a lot of times but still he was still fighting until the end even tho as we can see when Luffy loses g5, Kaidou fell to the ground because it was difficult for him to stay up.
Kaidou fought with the red Scabbards, then supernovas, then against Luffy alone for 3 rounds and he got 2 power ups and Yamato. Then both of them used their last technique that was hyped for 2-3 chapters saying that this is their last attack and now people say this is anticlimatic.
I like a lot that Kaidou was defeated the same way he appeared the first time, he appeared falling from the sky and making a hole in the ground. Now he fell from the sky and made another hole, it's just that this time he was able to go even more deeper.
I really can't understand the people that think that Kaidou will or should stand up once more, he is a beast not a godlike being
