Luffy properly learns and trains Haki during the two–year timeskip after the Marineford War, on Rusukaina Island under Silvers Rayleigh, between manga chapters 597–598 and anime episodes 516–517.

When does Luffy learn Haki?

If you’re asking “when does Luffy learn Haki” in the sense of formal training and conscious control:

  • Timeline: During the two–year timeskip between the pre–timeskip story and the start of the New World.
  • Manga: Around chapters 597–598.
  • Anime: Around episodes 516–517 (end of Marineford/post–war arc into the return of the Straw Hats).
  • Location: Rusukaina Island , a harsh island with extreme seasons and powerful beasts.
  • Teacher: Silvers Rayleigh , the “Dark King” and former right hand of Gol D. Roger.

Before this, Luffy had briefly and unconsciously used Conqueror’s Haki (like when he knocked out Motobaro), but he didn’t understand or control it yet.

What kinds of Haki does Luffy learn?

Under Rayleigh during the timeskip, Luffy trains in all three main types of Haki :

  • Observation Haki: Sharpened senses, predicting enemy movements, sensing presence and intent.
  • Armament Haki: Hardening his body and attacks to hit Logia users and boost offense/defense.
  • Conqueror’s Haki: Overwhelming the wills of weaker foes, knocking them out en masse.

An early post–timeskip showcase is him using Conqueror’s Haki in episode 518 to instantly defeat Demalo Black’s fake Straw Hat crew.

Mini timeline of Luffy’s Haki growth

Here’s a quick story–style rundown of his Haki journey:

  1. Pre–timeskip (unconscious sparks)
    Luffy accidentally triggers Conqueror’s Haki (for example against Motobaro), but has no idea what it is.
  1. Post–Marineford resolve
    After being overwhelmed by top–tier Haki users in Marineford, he realizes he’s outclassed and decides he must get stronger to protect his crew.
  1. Two years on Rusukaina
    Rayleigh shows him all three Haki types (famously on a giant animal), then puts him through brutal survival and focus training until Luffy can use Haki at will.
  1. New World refinements
    • With Hyogoro in Wano , Luffy learns to project Armament Haki (Ryuo) and use “inner destruction” to damage enemies from the inside.
 * Fights against **Katakuri** and **Kaido** push his Observation and Conqueror’s Haki into even more advanced territory.

FAQ style quick hits

  • Q: What exact episode should I watch to see him come back with Haki?
    A: Check around episodes 516–518 ; that’s when the timeskip ends and his new Haki skills start showing.
  • Q: Did he know Haki before the timeskip?
    A: He used Conqueror’s Haki before but had no training or understanding; the timeskip is when he truly “learns” Haki as a skillset.

TL;DR: Luffy truly learns and trains Haki during the two–year timeskip on Rusukaina with Rayleigh , between manga chapters 597–598 and anime episodes 516–517 , then keeps evolving those abilities through later arcs like Whole Cake and Wano.
