Chapter 613: Mermaid Princess in the Hardshell Tower
Cover: cover ministory series 19: From the deck of the world vol.1 "News Coo traveling the ocean"
On the newspaper the News Coo drops is the words "Straw Hat pirates are back!" and shows pictures of them at Sabaody
To the right of that, (in a different colum I guess) a word "Wapometal" is visible lol

first snippet

Coversation between Wadatsumi and Vander Decken
(Flying Pirates member: The Giant Watadsumi, A fishman of Giant Tiger Puffer)
(His nickname "Dainyuudou" is a folklore giant in Japanese myths)
Flying Pirates Captain Vander Decken IX, fishman of Japanese Bullhead Shark (Nekozame)

He told Princess Shirahosi that her life is DEAD or MARRIAGE.
It means she either swears love to him, or die.
He throws an axe, stating he'll send her an axe with picture of roses drawn on it.

next snippet

The scene changes to Ryuguu Kingdom, Princess Shirahosi's place
Luffy is trying to calm the crying princess down, and suddenly the axe mentioned earlier comes flying in from between the doors
Luffy notices it right away, and stop the axe
The guards come to the princess, but instead of handing over Luffy, she hides Luffy behind her
The guards tell her it's been decided to lock up all the Strawhats in the cell
They say Zoro is already caught, and Nami and Usopp is soon to be caught as well
After the guards leave, the princess and Luffy have a conversation
Vander Decken is cursed by a devil's curse called Mato-mato (Target-target) (most likely a DF)
Once he decided the princess is his target, his attacks make their way to her with precise accuracy, so she can't leave the tower

... wow, hey Usopp and Yasopp, there's a guy cheating with hax Devil Fruit out there guys.
The conversation between Luffy and the princess continues
She treats him to dinner. She says she's been locked up for a decade now
Luffy asks the princess out for a walk, and tells her if anything comes flying her way, he'll blow them all away

Scene changes to the palace
Nami, Brook, Usopp didn't agree to get caught easily, and are fighting
King Neptune is conflicted that although he doesn't necessary agree that they should be arrested based on fortune telling, for the moment he asks them to come quietly, and proceeds to attack them
Right as his attack is about to land, Zoro, who apparently escaped from prison, stopped Neptune's attack!
Zoro: I hear some festive songs playing... so I came!! (out)

Scene changes to Fishman town of Noa
Hodi and Vander Decken allies to take the head of King Neptune and bring down the Ryuguu kingdom
As they shake their hands, Decken tells him to wait a second and wears a glove on his hand.
(T guesses maybe the person he touches with his hands becomes his target)

more details

Vander Decken isn't wearing a straw hat... he's wearing a hat similar to ten-gallon cowboy hat, and he is four-legged.
