Step on the eye that has liquid dripping into it to the Stone Corridors.

In the maze take the path going up to the left and find/go between two silver forks to the Vanitas Void. In the maze, avoid chasers and find a table with Sonoko's head on it. Interacting with it gives the effect, along with a change of BGM and a small cinematic.

Odango (お団子)
(The Ohoshi-sama effect is required for this effect.)

Enter the red door to Dark World. Equip the Ohoshi-sama effect to light the area. Go right and down from the door. Enter a pink door in the middle of a large patch of leaves to the Tile Passage. Take the bottom exit of the path to the Teleport Maze. You will now be on a cube with tiles that will teleport you when stepped on.

Step on the following tiles: Left, Left, Left, Left, Bottom one, Right, Right again and finally the one above you. Interact with the NPC with the Odango hairstyle.

Teru Teru Bouzu (てるてるぼうず)
Enter the cream door to Sepia Mansion. Go down the hallway (don't enter any doors). Go down the stairs and take the bottom exit to the Rainy Garden. Go left and up from where you exit. Find the NPC pictured to the right to get the effect. (The NPC will usually be wandering around in front of a circular garden).

Minus Screwdriver (マイナスドライバー)
Enter the circular green door to Cinema World. Go down from the door until you reach a single still figure with flowers coming out of it. Go right until you reach a tree with a tree stump in front of it. Go down and interact with the scarecrow to the left. Interact with the white flower to reach Snow World.

Go straight up and then right through the Construction Path to the Wreckage Maze. Navigate your way downwards through the maze to a multicolored NPC (avoid the chasers). Interact with the sepia film screen.

Coat (コート)

Go down the Moss Path. Head up the stairs across the pathway then go left. Interact with the figure with the orange coat.

Itokenashi (イトケナシ)
Enter the cream door to Sepia Mansion. Go down the hallway (don't enter any doors). Go left to a separated way, choose the front exit to the Obsolete Alleyway, go straight left to the Docks and ride the boat to the Port, exit the place to the Swamp, climb a ladder to the Aerial Washitsu, enter the door and interact with the weird creature.

Boy (ボウイ)
Enter the dark blue door to Heaven. Go right and interact with the green bust. Enter the lake to the Lantern Cave. Navigate your way through the maze to a weird NPC which leads you to the Temple, interact with the neon NPC to the Neon World, interact with the small piece between two neon sticks to the Monochrome Town, go north and find an entrance to a building, go upstairs to the second floor, enter the last room and interact with the boy.

After getting the effect, the room will be permanently locked and Sonoko will be trapped in a dark version of Monochrome Town.



Music Box (オルゴール)
Enter the cream door to Sepia Mansion. Go down the hallway (don't enter any doors). Go left to a separated way, choose the right exit to the Mural Maze, choose up, left, bottom and bottom to the Abandoned Sea. Find a snail to teleport you to Glass World, then find an abstract glass that teleports you to a pathway leading to a secluded room with a giant horned girl. Interacting with her hand gives you the effect.

Apartment 401
Enter the cream door to Sepia Mansion and head straight through the halls without taking any doors or stairs until you reach the Obsolete Alleyway. When you see an open garage door, enter, then go up until you've reached the fourth floor; enter the right door.

This room is the only one in the Apartment Building to be occupied by an NPC - a green-haired girl. A radio plays in the living room that can be toggled on and off. By repeatedly turning the radio off, leaving the room, and entering, there is a chance the music will stop, but the radio still animates as if it is playing music. Interacting with it again distorts the room and turns the girl into a chaser, similar to the Uboa event of Yume Nikki. The door out will be stuck, and will require multiple interactions to unlock it and escape. Noticeably, returning to the room after this event reveals the door still locks itself and requires extra effort to open.

Note that if you equip the Minus Screwdriver in this room, the girl will begin shaking her head and backing away, distressed.

Temple Face
Go to the Temple and go through the banquet room to a place with a gray background and a set of eyes. Interacting with the edge pans the screen up and shows the face in full. There is a chance that chasers appear when looking at the face, seemingly connected to the Mini Dress effect.

Garden Patient
Go to the Wreckage Maze and find an NPC on the north-west side to teleport to the Lost Garden. Go bottom, right, bottom, then turn back. You will find a girl in bed, hooked up to medical equipment. Interacting with her causes Sonoko to start crying and wake up.

Warm Heart
(The Minus Screwdriver effect is required for this event.)

Enter the red door to Dark World and find a blonde girl to enter the Hospital. Interacting with the northmost door displays an image, but the eastern door takes you to a pathway ending at a metal safe with a pulse. Using the Minus Screwdriver effect on the safe opens it up, revealing a large beating heart and waking up Sonoko.
