Vice AdmiralGarp talked proudly to Ace at Impel Down about some of Luffy's actions, and mentions that they both have the blood of a world class criminal. Ace claims that Whitebeard is his only father since he took care of him after he went wild.
Meanwhile, on Vice-Admiral Momonga's ship in Boa Hancock's disguise, Luffy is worried about Ace. On the deck of the Marine Ship, Momonga spotted Captain Buggy's ship and it seems familiar to him. The Buggy Pirates spotted a Sea King that emerged adjacent to them and fell back into the sea. The Buggy Pirates were worried about their Captain that was taken away to Impel Down and wanted to free him, but it would be impossible for them to break inside. Alvida suggests that they should take a small boat if they want to get to Impel Down, so they conclude it would be too dangerous for them and quit the breakout attempt.
Prisoners of Impel Down are being tortured; a new prisoner refuses to obey another prisoner's orders and starts a fight. Minotaurus stopped them and took them both to a different prison cell where they were eaten alive.
Momonga's ship arrives at Impel Down through the Gate of Justice. Other Marine ships wait at the entrance of Impel Down. With all of the Marine ships, Luffy wonders if someone used a Buster Call. Momonga, Hancock, and Luffy, hidden under Hancock's cloak, departed the ship and enter Impel Down. Hancock struggled to put up with the Marine's love for her, but Momonga politely suggested to her not to petrify them. Around about this time, Buggy the Clown escaped from his cell on Level 1.
Prisoners inside Impel Down were screaming. Hannyabal greeted Momonga and Hancock at the prison. Hannyabal told Momonga that he wanted to see Warden Magellan of Impel Down. Vice Jail Manager Domino escorts Hancock to a room where she could privately search Hancock as usual with all visitors. Domino took her search on Hancock seriously by making Hancock wear a Seastone handcuff to disable her Devil Fruit powers. Hancock accepted it, but her heart is beating from the tension.
