Episode 437 of One Piece leaves a poisoned Luffy locked away to die while Bentham, disguised and determined, hunts through Impel Down for a way to save him. The trail leads toward a legendary miracle worker rumored to be imprisoned somewhere below.
With Luffy dumped into a frigid cell to succumb to Magellan's toxin, the captain can barely rise, let alone flee. Bentham, now wearing Hannyabal's face, scours the prison for him while keeping Buggy and Galdino close. The disguised okama learns the chilling truth that Magellan's venom has no antidote, but a whispered rumor points to a so-called miracle worker named Iva held somewhere in the depths. Pushing on through the Freezing Hell and packs of ravenous wolves, Bentham finally reaches Luffy's cell with keys in hand.
Magellan orders Luffy hauled to the central tower of Level 5 and finds his guards beaten near Hannyabal's post. The vice-warden blames a ballerina-style fighter once known as Mr. 2 of Baroque Works. In the interrogation room Bentham sheds the Hannyabal guise and reveals his plan to free Luffy, brushing off Buggy's warning that the captain may already be dead. When Galdino says only a miracle could help, the trio hears that a miracle worker named Iva sits inside Impel Down. Scanning a prisoner roster, Bentham worries Ivankov has been executed or released. The group freezes in the icy hell and battles the Army Wolves, with Bentham abandoning his disguise to fight. Inside his cell, Luffy writhes from the absorbed poison and spots Bentham approaching with keys.
