Episode 439 Luffy's Treatment Begins - Iva-san's Miraculous Power!!
While Ivankov is dancing around and joking with his followers, Bellett interrupts and declares that his father, once a king, one day paid a visit to Kamabakka Kingdom - and came back an okama! Because of this, the king's country and family were ruined, and his son was reduced from his princely state to a mere pirate. He fires his handheld cannon in vengeance, but Ivankov uses his Death Wink to repel the cannonball back at him, he then injects the burly man with female hormones and transforms him into a sexy female lady with huge female features. The intruder flees in embarrassment.
