How to Get Purification Ending Sekiro and Complete the Required Steps

Sekiro Shadows Die Twice offers players multiple narrative paths that dramatically alter the fate of Ashina and its protectors. Among these conclusions, the Purification path stands out as a bittersweet option where Wolf makes the ultimate sacrifice to ensure Kuro can live a normal human life. To unlock this specific outcome, players must navigate a complex series of eavesdropping sessions and secure a hidden key item before defeating the Divine Dragon.
Initiating the Path After Great Shinobi Owl
The journey toward this ending truly begins after you defy the Iron Code and defeat Great Shinobi Owl atop Ashina Castle. Once the battle concludes, you must visit Kuro in his room and exhaust all available dialogue options to advance the story. Instead of proceeding immediately to the next area, hide behind a nearby wall screen to eavesdrop on the young lord's private thoughts.
After overhearing Kuro speak about his duties, rest at the nearby Sculptor's Idol to update the world state. You will notice Emma has moved to the top of the stairs, where you must speak with her and agree with her desire to find a way to save Kuro without killing him. This conversation establishes the foundation for your secret investigation.
Investigating the Old Grave and Dilapidated Temple
Following your initial agreement, Emma will relocate to the Old Grave area located on the outer left side of Ashina Castle. Travel to this waypoint and speak with her again to learn about her progress and her visits to the graves of ancestral doctors. She will then mention needing to speak with the Sculptor back at your original resting base.
Fast travel to the Dilapidated Temple and walk around to the backside of the building to find a small hole in the wooden wall. Eavesdrop on the conversation between Emma and the Sculptor to uncover their hidden findings regarding a special bell. Once you have gathered this critical information, confront Emma inside the temple to receive the Father's Bell Charm.
Conquering the Altered Hirata Estate Memory
With the Father's Bell Charm in your possession, interact with the golden Buddha statue inside the Dilapidated Temple to enter a heavily modified version of the Hirata Estate. This timeline features far more aggressive enemies and entirely new mini-boss encounters that will thoroughly test your combat reflexes. Navigating this area requires immense patience as you fight your way back toward the main burning courtyard.
At the end of this grueling memory, you will face Owl Father, who stands as one of the most mechanically demanding bosses in the entire game. Defeating this phantom version of your former mentor rewards you with the Aromatic Flower key item, which is mandatory for the final quest step. Ensuring you secure this item before challenging the Divine Dragon is vital, as completing the Fountainhead Palace zone will permanently lock you out of this memory.
Delivering the final Ingredients at Ashina Castle
Once you possess the Aromatic Flower, you can safely progress through the remainder of the mainline campaign until you defeat Sword Saint Isshin in the secret silvergrass field. Approach the fallen Divine Heir to trigger the final interaction menu of the game. To achieve the desired outcome, make sure to select the option to give Kuro both the Dragon's Tears and the Aromatic Flower. This choice triggers the emotional cutscene that seals the destiny of the Shinobi and concludes your journey.
