Chapter 539

The 539th Chapter of One Piece is called "Emporio Tension Hormones".

Level 5.5, New Kama Land
The chapter starts in New Kama Land, Level 5.5. Trays of food is being hauled over to Luffy, from meat to vegetables, from fruit to fish. Everything gets sucked in, due to Luffy's eating habits. A random person stated that Luffy had been eating for a full hour. Luffy kept using his Gum Gum powers to draw in food. A man states that New Kama Land is losing days of food provisions. Mr. 2 just stares in shock while Iva comments on Luffy's will to live. Luffy soon finished eating, he shouts "I'M ALL BETTER!" and is cheered on by the people, saying that he survived Magellan's poison. Mr. 2 faints from extreme exhaustion and Iva says how Mr. 2 cheered Luffy on for hours. Although Luffy was told to rest a few more days, Luffy still insists on going forth, down to Level 6, following his Vivre Card. Iva simply says "It's your life". Luffy asks Iva if he was gonna break out of Impel Down, as Mr. 2 had gone down to Level 5 to break the former Queen of the Okamas out. Iva replies with that the situation of the World was too fierce and that one man, other than Whitebeard and the Shichibukai was to react. This man was a compatriot and his name is Monkey D. Dragon, which Luffy simply replies with "Oh. You mean my dad." Iva agrees and says the moment Dragon plans to lead the Revolutionaries, Iva would instantly hurl himself into the fray.

Suddenly, Iva realizes what Luffy had just said, and is taken completely aback. Iva finds it hard to believe that Dragon had a son. Luffy says that he wasn't supposed to tell anyone and was to keep it a secret. However, Iva seems to believe it and thinks to himself about the current situation, that it all fits together: Luffy's status of a Supernova and his unbelievable will. He quietly asks Luffy where he comes from and Luffy replies with "East Blue".

Iva's Flashback
Monkey D. Dragon is seen standing towards the east and Iva sitting on a rail behind him. Iva comments on Dragon's habit to face towards the east, no matter where the winds lie, asking if it was the direction of his homeland and asks if he left family in the eastern seas. Dragon quickly replies with an order not to delve into his personal history

Level 5.5, New Kama Land
Iva quickly gets Inazuma to find the departure time for Ace, saying that he will accompany Luffy to Level 6 of Impel Down. Iva quickly tells Luffy that he is one of Dragon's nakama, a leader in the Revolutionary Army, that being the reason why he was imprisoned. Iva summons the ones willing to join them and Luffy shouts that he will save Ace but falls down. Iva couldn't find any pulse and uses "Emporio: Tension Hormones", which gives the victim a day's worth of Adrenaline
