Unknown Location
However, as time passes, Mr. 2 wakes up to a room where there are a number of people drinking beer and eating gourmet food. They all are in clothes and all are partying. Two women state that he still is in Impel Down. The person who found Luffy and Mr. 2 reveals herself as Inazuma. She confirms that Mr. 2 had been asleep for 10 hours and soon after that, Mr. 2 bombards her with questions when suddenly, the lights go out and a person is seen taking the stage and calls out Mr. 2's name, to his surprise. This person confirms that to get to the "Prisoner's Paradise", you must go through "the road that can't exist". He labels the highlights of this place and abolishes the "myth" of prisoners being "demoned away".

Level 5.5 New Kama Land, the Prisoner's Paradise
Emporio Ivankov takes the stage and is seen performing with a number of men behind him in fishnet stockings. Iva welcomes Mr. 2 to his New Kama Land. Mr. 2 calls out Iva-chan, where other prisoners mutter that saying that is rude. However, Iva doesn't mind, saying "You could call me crap!" but then shouts that he doesn't want to be called crap. A man shouts "Emporio Ivankov!", then goes on and tells a story of his family, where his Father, a Royal King, traveled to Kamabakka Kingdom, where Iva had been once Queen. The man goes on to say that his father came back as an Okama and that he became a pirate. He said to Iva, that before he rots in Impel Down, he would kill Iva first. Iva instantly tells him to drop the massive gun he's holding, that it could potentially kill him. However, Iva suddenly shouts "I won't die!" and a relieved audience just sighs in relief. Despite this, the man fires a cannonball at Iva. Then, Iva does something extraordinary. Iva looks at the cannonball, says "Death Wink", winks, and repels the cannonball. This ultimately leads to the man himself being hurt by his own cannonball, exploding in smoke but not dying. Iva appears in front of the man and shouts "Emporio: Female Hormones!". The man starts transforming and during that, Iva says "Two mothers and a daughter! Get along!" and ultimately turns him into a her. The new female runs out, embarrassed. Iva simply shouts that they were here in New Kama Land, to transcend gender, to create a new race. Suddenly, Mr. 2 bows and asks for Iva to heal Luffy, as Iva had been nicknamed the "Miracle Worker". It is then revealed that Luffy had asked Iva to heal Mr. 2, rather than to heal himself. However, Iva decided to heal Luffy as well and Luffy had been screaming for 10 hours straight.
