Area Clearance Order: After collecting all three ritual items (Mortal Blade, Lotus, Shelter Stone), all Ashina Castle Idols (except the Dungeon Entrance) will become locked due to a Shinobi invasion. Fast travel to the Abandoned Dungeon Entrance Idol. Grapple up the bottomless pit and make your way back into Ashina Castle. The castle is now flooded with purple Ministry ninjas fighting the Ashina elite. Proceed cautiously through the grounds.
Area Clearance Order: Grapple along the castle rooftops following the same path as before to re-enter the Upper Tower Antechamber. Stealth past the battling samurais and ninjas, and ascend the stairs toward the Ashina Dojo. Do not rush into the room! A purple ninja is waiting in the corner. Sneak in, backstab him, and use the Puppeteer Ninjutsu to make him fight Lone Shadow Vilehand for you. Use Mikiri Counter on Vilehand's kicks and defeat him to claim Prayer Bead #29.

Items to Keep Picking Up:
Area Clearance Order: Head back to the Old Grave Idol and make your way down the forest path behind the castle towards the Great Serpent Shrine. Here you'll find Lone Shadow Masanaga the Spear-Bearer mourning. Drop onto him from the roof for a stealth Deathblow. Keep pressure on him and throw Shurikens to interrupt him whenever he tries to whistle for his poison dogs. Defeating him rewards Prayer Bead #30.
Detailed Shrine Combat:
Items to Keep Picking Up:
Area Clearance Order: Return to the Upper Tower Antechamber. Instead of going to the Dojo, look down into the ground floor lobby where a Chained Ogre has broken loose and is fighting Ashina guards. Drop down onto the wooden crossbeam, lock on, and deliver a plunging stealth Deathblow to the Ogre. Then use Flame Vent to burn away his remaining health. He drops Prayer Bead #28 and the Shinobi Medicine Rank 3 passive skill.
Rafter Plunge & Fire Burn: Stand on the upper interior beam overlooking the ground floor lobby. Drop down directly onto the Ogre for a free stealth Deathblow! Throw Oil + Flame Vent to incinerate his remaining health bar.
Items to Keep Picking Up:
NO — You CANNOT cancel or exit Owl's dialogue once started!
When you walk up to Great Shinobi Owl on the rooftop and press the interact button to speak with him, you are locked in. When the menu pops up asking you to choose between Obeying the Iron Code or Breaking it, there is NO "back" button or "let me think about it" option. You must choose one immediately.
Rest at Upper Tower — Ashina Dojo idol (right below roof). Step onto roof, see Owl, but DO NOT WALK UP TO HIM OR TALK TO HIM YET. Exit to main menu and copy your save file (%AppData%\Sekiro\<SteamID>\S0000.sl2)!
Before choosing your path, review the dedicated guides and step-by-step walkthrough parts for every specific ending route:
Area Clearance Order: Ascend out of the Dojo window to the snowy rooftop. You will find Great Shinobi Owl waiting for you. This is the crucial story branch. Choose "Break the Iron Code, Stay Loyal to Kuro" to face him in battle. Owl fights similarly to you, utilizing firecrackers, shurikens, and anti-healing bombs. Defeat him to claim the Memory: Great Shinobi Owl and the Aromatic Branch, completing the three required ritual items.
Detailed Shinobi Master Strategy:
Shura Ending: Choosing "Obey the Iron Code" triggers fights against Emma & Isshin Ashina, concluding the game early with the evil Shura ending. Staying loyal to Kuro opens Fountainhead Palace!
Items to Keep Picking Up:
The Shinobi Siege has concluded, and depending on your choice, you are either locked into the Shura ending or moving forward to Fountainhead Palace. If you stayed loyal to Kuro, head to the Wedding Cave Door in Ashina Depths to enter the Palanquin.
