Duster is given a mission by his father Wess to infiltrate Osohe Castle and steal an item. After he finishes speaking, head down the stairs to the left and pick up five more Mystical Thief Tools to add to your collection; the Wall Staples from the previous chapter are still there. When you leave the house, head around the left side and behind it to open a Present; it periodically refills with items. Head towards the village square to the west. You can speak with Mapson on the bridge to mark Osohe Castle on the map. He also mentions that the drawbridge is up, but that Nippolyte may know something about an underground passage.
As it is nighttime, many of the houses are locked. The Yado Inn is still open and has a room to sleep and another room with a Save Frog. Head north to leave the square and you will run into an unnamed man and a monkey; they head to Yado Inn and occupy the middle room that you will not be able to enter. Continuing onwards leads Butch to show Duster a bag of money he received which he hides in the village well. Interacting with the well will reveal 50,000 DP that Duster puts back.
Entering Cross Road triggers a cutscene. When it ends, head north into Sunset Cemetery where zombies accost Duster and throw him into a battle. If you received a Thunder Bomb from the back of the house, use it to kill off the Zombie Ladies and severely weaken the Zombie Guys. When the battle ends head to Yado Inn to heal up. Return to the Cemetery and head up to Osohe Castle. The drawbridge is up, so head back to the Cemetery. On the way back Duster is stopped by an ant that teaches him how to use timed hits. For more information see Battles.
When you return to the Cemetery you see Nippolyte enter the shack. Follow him and go down the stairs inside. Pick up the Beef Jerky and Peculiar Cheese from the Presents and talk to the Save Frog. Position Duster on the left side of the bookshelf and hold 
to move it.

Talk to Nippolyte who tells you that the gate is locked and that you would need to climb the walls to get in. Head straight up from the passage entrance and interact with the strip of wall that is lighter in color. Duster creates a Wall Staple ladder up to the third floor. Attempting to enter the open doorway triggers another conversation with the ant from earlier about timed hits.
Head through the left door to pick up a Rotten Milk. Your way here is blocked so return to the previous room and dash into the statue to make it drop the ball it is holding. The ball will create a hole in the ground that you can take to 2F. You can scale back up the wall with Wall Staples at any time. Do not open the Present in this room as a Stinky Ghost will pop up and inflict Duster with Nausea. Enter the door and go down the stairs to pick up a Fresh Mint.
Go down another flight of stairs to reach the main floor. You can unlock the castle gate here to create a shortcut. Head into the left room to find a Save Frog and a Present holding a Fresh Mint. You can head downstairs to a room with a hot spring to restore HP. Return to the main lobby and head up through the doors.
There are four doors here. The middle door leads to the Ghost Bazaar which trades items for any Rotten Eclairs you may have in your possession. Possible items include the Rope Snake (1 Eclair), a Fresh Mint (1 Eclair), and Beef Jerky (2 Eclairs). The one directly to the left of the Bazaar has a Present containing the Battle Memory, which lets you relive enemy battles to get the timing when attacking them. The one to the right of the Bazaar has two Presents that contain Rotten Milk and Beef Jerky. A ladder leads into an underground passage blocked by a stone face and depictions of dances drawn on the wall. The door on the left takes Duster upstairs.
Go into the first room to pick up a Chick Bandana; the fireplace here returns you to the room with the Save Frog before the hot spring. The room on the right leads into a banquet room. Talking to the ghost on the far right will give you a Rotten Eclair each time you enter the room. There is a kitchen to the southeast that has a map of the area in the blue Present. Interacting with the moving jar on the table starts a fight with a Strawberry Jam. Interact with the differently colored section of the wall to scale it with Wall Staples. On the next floor, go through the east doorway to pick up two previously inaccessible Presents. The one next to the rubble and below the other one contains a Stinky Ghost that gives Duster nausea, while the other contains an Aquarius Bracelet.
Return back to the room with the gap and cross it with the Rope Snake. A friendly ghost guards the door to a tough enemy. Enter it and pick up Durable Shoes from the Present in the corner.
