Defeat Owl on your return to
Ashina Castle (Dusk) after obtaining the Immortal Blade, Lotus of the Palace, and Shelter Stone.
[*]Head to Isshin Ashina in his tower nearby and eavesdrop on him and
Emma.
[*]Rest and then eavesdrop on your
Lord Kuro by going behind the screens at the back of Kuro's Room.
[*]Rest and speak with
Emma, who has moved up to the Castle Tower Lookout. Choose the option to agree that
Lord Kuro cannot be allowed to die.
[*]Rest, and speak to her again to receive Tomoe's Note, and learn of the path of Purification.
[*]Warp and speak to
Emma again near the Old Grave
Sculptor's Idol, on the other side of the small building.
[*]Head back to
Dilapidated Temple, where
Emma is with the
Sculptor. The
sculptor mentions the room is drafty, and you can eavesdrop on
Emma and the
Sculptor from the back of the building near a hole in the wall.
[*]Speak with
Emma and choose the option to ask about what you overhead. Persist and ask her to reveal the truth, and receive Father's Bell Charm from her.
[*]Use the bell to pray to Buddha. This unlocks a more difficult version of the
Hirata Estate - which begins where you met Owl, only now there is a Lone Shadow Mini-Boss you must defeat.
[*]Use a new shortcut past the Lone Shadow to re-fight
Juzou the Drunkard and some tougher
enemies as you make your way to the Audience Chamber.
[*]Heading to the
Lady Butterfly boss room, you'll need to defeat Owl again, only he is a much tougher version to face. Defeat him to earn the Aromatic Flower.
[*]After defeating him, progress through the story as normal until the end fight against Sword Saint Isshin
