After claiming Everythinggj, return to the main menu, select "Mirror Travel," choose "Approach Path," and hold F to teleport there.
After teleporting, you'll arrive at Kiyomizu-dera Temple in the DEMO. Hold SHIFT to run.
Keep moving forward and defeat the two Genma ahead.
Defeating enemies drops not only Yellow Souls but also souls of other colors. Red Souls can be used for various upgrades.
Continue forward to a wooden door. Defeat the group of Genma guarding the entrance.
Push the door open. There's a chest by the roadside ahead; open it to get a "Small Revival Pill." Press Q to use items, and hold TAB to switch between them.
Keep moving forward, heading toward the Oni Stage. Press H to open the map and check your destination.
Follow the path. You'll encounter several enemies along the way. Keep an eye on the archers' arrows and use block or dodge to avoid them.
At the corner ahead, defeat the two melee Genma first to unlock the main path on the right.
Head up the newly opened path to the right, pick up the glowing item on the ground, and take out the archer on the left.
After defeating them, jump straight down. There are Onibi (ghost lanterns) to collect on both the left and right sides.
Continue forward. First, head to the platform on the left, then circle around to the platform on the right. There's a chest on the right platform containing the material "Whetstone".
Continue forward to reach a new save point. Break the chest on the table to the left for materials (drop rate may not be 100%), and save your progress.
