|Role||To trap Urotsuki in inescapable places.|
If you use the Eyeball Bomb effect to return to the nexus after being caught by a chaser, other chasers will often appear in places where they usually aren't found, and will continue to appear and chase Urotsuki until she is caught.
Here is a list of all the chasers in the game.
Shadow Ladies/Black WitchesEdit
Shadow Ladies are the main chasers in Yume 2kki and are equivalent to the Toriningen from Yume Nikki. They are found in many places in the dream world and will trap you in a small area or maze you can not get out of. Special "Flat" shadow ladies also appear in certain events, which are shaded slightly purple and flat like a cardboard cutout when moving left or right. They also bear a high resemblance to the Gray Man from the game LSD Dream Emulator.
Clowns are another main form of chaser in Yume 2kki, and work much the same as the shadow ladies. There are many throughout the dreamworld, some of them sane and some insane. The laugh they let out when they catch you sounds exactly like Smile-san's laugh. Unlike other chasers they do not react to the Invisible effect, making them hard to avoid in some cases.
One sane clown can be found in one of the rooms of the gray building in Guts World. If you chainsaw it, it will steal your money, and if you don't have any money it will chase you and trap you in an enclosed area like any other clown.
The Shadow Bird is a large black bird creature with empty red eyes, about as tall as Urotsuki. It chases after you at a fairly average speed and will trap you if it catches you. It appears to be based on the Mothman.
One can be found at the Storage complex at the end of the Highway's north east road.
Shadow Gloop/Black SlimeEdit
The Shadow Gloop is a large black blob monster with wiry arms and big red eyes. It chases after you extremely slowly, and is easily outrun by Urotsuki. It has a slight resemblance to Swalot from Pokémon.
The Shadow ??? is a strange black creature with long grey arms and googly red eyes. It chases after you quite slowly, and is easily outrun by Urotsuki, but can be hard to avoid in small spaces.
Scary Faces are floating faces with crazy eyes and sharp teeth. If one catches you, you will be sent to a enclosed part of the Stone Maze shaped like a cross or a table surrounded by nails in Blood World.
In the Stone Maze, using the Insect effect will let Urotsuki pass straight through them unharmed.
The vengeful Spirit is a chaser that wanders the Shinto Shrine, wearing a torn green cloak and a white triangular mask, both dripping with blood. It can be found in the center of the largest room in the Shinto Shrine, near the cherry blossom painting.
It appears under many different circumstances, but the simplest way to make it appear is to equip the wolf + bike combo effect and then check the PC in your Dream Room at the start of a new dream.
White eyes are found in Geometry World in the maze. They simply send you back to the entrance of the maze and giggle, taunting the player.
Evil Bugs appear in the Red Bug Maze event. They block you from certain exits and function in the same way regular chasers do.
Found in only the School and functions similar to a chaser. Using the Glasses effect near him reveals that he's actually a ghost. Although normally he won't harm you, using the Bike effect in the School causes him to become insane and chase you, and if you get caught you'll be transported to a staff room where you'll be in what appears to be 'detention' while he scolds you. Trying to walk away causes the Teacher to jump up and force you back to your place, so your only means of escape are waking up or using the Eyeball Bomb effect. Chainsawing him causes him to turn into a ghost and follow you, although he is very slow. Getting caught causes you to wake up.
If you escape the room, you'll actually end up walking out of the last classroom in the School, the most unkempt classroom of all. Getting caught by the Teacher again while riding your Bike sends you back to detention, but this time he'll already be a ghost and start to chase you (and oddly, he's even more transparent this time).
Found in the Underground TV Complex. Normally she wears a surgical mask over her face and doesn't pay any attention to you, but if you chainsaw her you'll hear a faint scream, she'll face away from you and her sprite will temporarily turn black. Her entire face then turns into a giant mouth with a long tongue and she'll begin to chase you around the room. The doorways in the room also become blocked, so you'll be trapped in the room with her until she catches you. Once caught, you'll be transported to area that looks exactly like the same room you were in, except all the doors on all the rooms will be missing. The Mouth Girl will also be in the room with you (still in her insane form), but she no longer chases you or reacts to any effects.
Found in the Laboratory in both the facility as well as the caves below it. The scientists in the facility are passive by default, but will become hostile once the Director NPC is killed. Getting caught by scientists in the facility will lead to the Hallucination event. The scientists in the underground caves are always hostile and will teleport Urotsuki to an isolated catwalk upon which she is observed by them. Unlike most other chasers, scientists react to the Chainsaw effect by running away from Urotsuki and can actually be killed if chainsawed.
Found only as part of the High Priestess event, these chasers are unique in that Urotsuki can come into contact with them several times before being teleported away. They do not react to the Invisible Effect making them hard to avoid.
