'One Piece' chapter 809 just got released and it was a flashback of the fierce battle that happened between Inuarashi vs. Jack, as well as Nekomamushi vs. Jack.
Here's the chapter summary courtesy of Manga Spoilers.
The chapter began with Chopper continuing the story about Caesar's weapon and Robin recapping the negotiations that was happening between Caesar, Doflamingo and Kaido.
Also, it was revealed that Inuarashi knows Shanks when he ventured to the sea along with his former best-friend, Nekomamushi. He recognized Luffy's Straw Hat but when the Straw Hat captain began telling the story, the Duke fell asleep.
It was revealed that Inuarashi rules the Minks in the city and is the one in charge during daytime, while Nekomamushi commands the forest Minks and takes over at night.
Apparently, something happened between the two that they want to kill each other the second they go eye-to-eye. Both are equal in strength as well.
Every mink that resides in the town falls asleep including Sicillion.
Another flashback ensues, with Jack destroying everything and the Musketeers finally arriving at the scene. Wanda warns them to be careful of their opponents as they have the ability to shape shift.
The Duke finally arrives to meet Jack. They tried to negotiate with Kaido's henchman but to no avail. He continues to wreak havoc in the city but he was stopped effortlessly by Inuarashi.
The pirates were shocked with what they saw but were confident with their captain's ability as his bounty is apparently set at 1 billion berries.
Again, Jack continues to demand for Raizou. However, the time hit 6 PM and a loud roar from a cat was heard coming from the Forest. Inuarashi orders his men to retreat as there is no way their fighting with the forest Minks. They decided they will just resume attacking the invaders when their time arrive.
Nekomamushi arrives at the scene. He said, "This is my country while the moon is out. Don't let the intruders escape." He then attacks the pirates with some ferocious attacks. "Don't think you'll leave here alive!" Cat-Viper throws Jack like he was nothing but destroying some part of the town in the process.
He tells Jack, "Listen here. You came here to look for a warrior from Wano? No samurai has stepped one foot on this island. If one does, I'll kill them. I AM CAT-VIPER, THE MAN WHO WAITS FOR THE WORLD'S DAWN!"
Then, Jack returns to his human form but it was only a silhouette. Next chapter, his appearance will finally be revealed.
