DADDY LONGLEGS is a tall, completely black figure, with long claws for hands. He wears a small hat and boots and appears to be holding a cage or a lantern.
Throughout the player's journey, talking to him multiple times results in different dialogue that seem to mainly talk about the HEADSPACEOMORI resides in. Like most minor characters, he has a vague personality, but is suggested to be caring as he frequently offers to bring the team out of the LOST FOREST, knowing it is a dangerous journey.
OMORI and friends encounter DADDY LONGLEGS at the beginning of LOST FOREST, and he appears in every room as they progress through the forest. Speaking to him will give the player exposition on the nature of the forest, and every other time he is spoken to, he warns that this journey is not for the faint of heart, and will offer to guide them back out of the forest.
After getting to the end of the LOST FOREST, DADDY LONGLEGS gives a vague speech that is more directed to the player rather than OMORI and friends. He tells the story behind HEADSPACE and how the WHITE SPACE came to be what it is now. After he completes his story, he walks into the campfire in the middle, burning himself alive. This produces one of the keys needed to complete the HANGMAN puzzle.
DADDY LONGLEGS also appears in one of the rooms in BLACK SPACE 2, sitting in a chair; where he tells the player to turn back from going down more sets of ladders "before it's too late".
He always says this first. The rest, he says based on how many times you entered any map in the lost forest.
Welcome to the \cLOST FOREST\c, where you find things you never knew were lost in the first place...\! Or perhaps they're forgotten for a reason.
He always says this stuff, left as is so the player could know how hot or cold they are:
I suppose we all hold secrets...\! No matter how lost or how deep down we bury them, they find their way back to the other side..
Trying to lose yourself? Or have you accomplished that already?\! Either way, this is the right place for you.\! Perhaps that's why you've come here... to finish the job.
Usually we tend to do things we want... as opposed to things we say we do.\! I've never been one for wants.\! I'm more of a "need" kind of person.
I suggest you look for the exit before your "needs" become more apparent.
You've wandered by me \v times.
If：Lost Forest Entrances 8
You're still here?\! You must have either given up or you have fully embraced your fate.\! A confession perhaps, but I'm not the one to tell.
You have passed by me \v times.
If：Lost Forest Entrances = 9
There was a boy wandering around here before, very similar to you.\! He went into the darkness and never came out.
How regretful it must have been to never find what he was looking for.\! Be it regret, defeat, or confusion, no one will know.
If：Lost Forest Entrances = 12
I've seen lost and I've seen blind, but the combination is unsettling.\! Perhaps you are hiding away from the right way.
If：Lost Forest Entrances = 15
Morals are lost on the wicked.\! How does one define malice without intent?\! Why do you continue down this path when it's most certainly not the right way?
This stuff is unique to the map that you're on. He says it directly after the stuff above.
There is an old saying about wasting time when living a life that is not your own.\! Dreams can feel like that, like this forest.\! Lost...
Sometimes when we hide things from ourselves, we create different truths and eventually forget our way.\! Have you found yours yet, or are you still lost?
Forget all you will, or try to.\! Darkness manifests whether you are aware or not.\! Hide the inhabitable behind ignorance and watch your lie fall.
Once you complete the forest, his page 2 is always:
The darkness surrounds you and it is a terrible thing, but your “truth” has guided you.\! How much longer can you keep it?
You have reached the end of the \cLOST FOREST\c... but the beginning of the truth.
I will tell you a story that has been lost through time...\! a story about the creation of this reality.
In the beginning, there only existed two...\! the DREAMER and his room.
The DREAMER grew weary of his room and created a door that led to many different worlds.
Walking the path as a visitor to these worlds, the DREAMER would come and go as he pleased.
Slips and falls, tumbles and drops...\! the DREAMER's curiosity and clumsy exploration eventually led him to a certain world.
One not like the others...\! one painted with chaos and bathed in darkness.
The DREAMER slowly became filled with dread. \!Quiet as they may have been, words of malice quietly crept into his mind.\! Whispering lies, secrets, and truths.
Powerless to silence the noise, the DREAMER manifested benevolent entities in his different worlds...
Then he compounded his worlds above the dark realm...\! sealing it with their combined might.
Yet despite his valiant efforts, the darkness's presence never abated.\! Even with new allies, the darkness continued to scrape and scratch at the back of the DREAMER's mind.
The noise might have subsided, but it never went away.
The DREAMER could run and bury away his fears, but one still has to face his own reflection.
What the DREAMER had created was something he could not be a part of, something outside himself.
The DREAMER's own power was his greatest adversary.\! Knowledge... or the absence of it, would become the DREAMER's greatest gift.
To truly escape the perils of his own faculty and ascend to a blissful state of ignorance...\! Only then would the noise cease to agitate the DREAMER's sanity.
So...\! the DREAMER took on another name...\! and chose to forget himself.
From that time on, the DREAMER has lived amongst us... \!simply as an inhabitant of this world...\! Traveling along blissfully, ignorant of his own fabrication.
This journey is too arduous for those faint of heart.\! Do you wish to leave, children?\! I will not blame you.
Do you understand, children?
text: \n<DADDY LONGLEGS>Good.\! Now, I will leave you with a warning.}}
text: \n<DADDY LONGLEGS>I'm sorry. As conflicted as I am, this tale was not meant to be repeated.\! Now, I will leave you with a warning.}}
text: \n<DADDY LONGLEGS>Children, I must warn you...}}
As with all things that are born in and out of this world, an end will threaten this one too.\! Though the DREAMER may have subdued the inexorable, the darkness grows still.
No bandage can stifle an eternal wound...\! and there will be a time when its influence will bleed through.
Forgetful the DREAMER may be of this peril, a peril never forgets to be.
Yet, the end of this world may be an inevitability.\! The DREAMER is the only one with the ability that can truly set this world free.
His name is based on a spider  that's commonly known as a Daddy Long Legs, likely because PYREFLY FOREST is home to many spiders.
If the "WTF" value is 9 or higher, he will appear in PYREFLY FOREST on the same room with the RARE BEAR.
