Sekiro Sunken Valley
To start things off, head to Kuro's Room in the Upper Tower of Ashina Castle. At the altar, turn right away from the small library and look to the back right corner. There is a window that leads to the rooftops of Ashina Castle. Once you reach there, look down and right to see a bridge with two guards. Use the grappling hook to reach the roof to your right, head down and get past the guards and onto the bridge. Once you cross, move through some bushy area and be prepared for ambushes by monkeys. Look for a small gazebo with a mysterious man from earlier inside. Speak to him and then look for the nearest Grapple point. Jump off towards it to cross the ravine. Now you will have arrived at the Sunken Valley.
Once you turn left and head into the Valley, be prepared to fight Giant Apes and a Long-Arm Centipede Giraffe before getting such items as Divine Confetti, Divine Abduction Prosthetic, and a flower for Lord Kuro.
Sekiro: Shadows Die Twice is an intriguing world with many secrets. It can all be unlocked by first defeating the Chained Ogre.
