Omori Symbolism & Themes

This guide is a collection of symbolism and common themes throughout Omori to help you understand the story. Major spoilers will be unmarked from this point on! This is definitely a read-once-you’ve-beaten-the-game thing, final warning.If there are missing terms/concepts/symbolism you’d like me to expand on please leave a comment.

A japanese term for a shut-in to an extreme degree. Not simply shy, these people shut themselves out from everything as much as physically possible to an utterly debilitating state.

Ending Spoilers
Sunny was NOT a Hikikomori until Mari’s death. Whether he manages to overcome his present state depends on the Route you choose, whether to answer Kel at the door or not.
White Space

Nothingness, emptiness. This is an empty room Sunny locks himself/Omori in to avoid..everything. White is often symbolic of purity or emptiness, in this case both.

Head Space

The name of the world map is “Headspace”, basically it’s the world of Omori’s delusional dreams. Here Omori lives out an idealized version of his former life with his former friends. The colors are saturated and happy to an extreme, and absurd fantasies can be found readily.

As you look around the real world you’ll find inspirations for many of the things here. Everything is a whimsical interpretation of something or other, such as money being literal Clams.

It is implied that Headspace is destroyed and recreated once Omori finds a hidden truth, trying harder to bury it each time. In the demo, this truth is in the Barn in Otherworld.

Real World

Not sure what else to call it but the awake sections are (mostly) actually occurring rather than Omori’s delusions. Delusions will manifest as minor or major apparitions that either fade away when interacted with or suddenly disappear.

Black Space
Ending Spoilers
If Whitespace is the nothingness Omori has been using to suppress his memories, Blackspace is everything that was shut out by Whitespace.

His anger, sadness, and fear are kept here, literally locked away by the Keys. He can’t make a personal revelation and deal with his feelings without coming here.

His fantasy keeps killing Basil here, obviously due to his involvement in Mari’s death. Whether it’s guilt lashing out at Sunny himself and Basil, or Sunny’s subconscious trying to keep Basil from revealing the truth to Omori I’m not sure.

Black is often symbolic of the unknown or evil, in this case probably both.


Sunny is the Dreamer, though Omori is his manifestation. Sunny is literally dreaming when in Headspace, and is thus the source for all you see in it. Only a few entities in Headspace recognize him as the Dreamer, all tucked away very deeply.

Omori’s Knife

The knife seems to stem from Sunny’s depression and fascination with suicide and violence. At once it represents a self defense tool and a means of punishing or killing himself. He seems to have gotten the idea simply from the steak knife in the kitchen rather than any specific trauma.

The knife grows rusty and terrible over time in the dream world, oddly rendering it stronger, perhaps because it would be more painful to be cut by it (though it would do a far worse job at actually cutting). In the hikikomori route a new red knife with “something that can be seen in the blade” is found, and Omori stabs himself much, MUCH more often with it, and Sunny is given the option to manually do so himself.

Of note, Basil seems to have come to a similar conclusion with his own knife at the end of the normal route.

In the normal route, the knife is used more as a self defense weapon (though it’s quickly taken away by Kel). It can still be used by Sunny for suicide in one ending however.


The default name of the player character in the Real World. I’ll admit, I have not consistently referred to Sunny separately from Omori through this guide, but technically they are different, sometimes.


The black and white player character.

Ending Spoilers
Omori is the name of the boy Omori dreams of himself to be, a perfect blank slate who lives an idealized version of his former life. He has no reaction or dialog, seeming to be the very avatar of his state as a hikikomori even though his dream world “friends” don’t treat him as one.

Omori is also the brand of Piano that Mari played. You can inspect the piano (and another one in town) and see the name Omori written on it. You’ll note Omori is black and white like a piano, his shorts look like piano keys, and his tank top is black and very vaguely like the open top of a piano.

It’s possible the piano connection is either him wanting to be nearer to his sister (jealousy of her playing it more than talking to him), or a manifestation of the piano as an enemy or rival (seeing omori as a bad person, like the piano).

It’s surely also no coincidence that Omori is the last part of Hikikomori.

White Egret Orchid

In the language of flowers, it symbolizes the phrase, “my thoughts will follow you into your dreams.” At least in the world of Omori it does, I can’t find any real world evidence that this is an accepted symbolism for the plant. It is, however, symbolic of Mari and Omori’s inability to keep his thoughts of her out of his dreams, even in the Hikikomori route they are plentiful.

Playground Kids

The kids in the Playground are all the other kids from Sunny’s town, mostly Aubrey’s gang. Likely due to their distance from Sunny, they’re remembered as much more stylized creatures than his in-group, who are all human.

Something/Black Eye

Note there are two Somethings. Basil has his own Something, a web of black strands reaching outward like a mouth, while Omori has a tall black shadow with a single vertical eye.

Ending Spoilers
The black smear with the single eye is Mari’s dying body. The black drape is her messy long black hair as she hung from the tree and the eye is her eye as she looked at Sunny and Basil running after they roped her up.

Something is always present in Headspace and disappears once Omori notices it, symbolizing his repressed memories popping up. Infrequent and brief, but unavoidable. Basil is the only character in Headspace to acknowledge it as he is the only other one there who knows that they killed her.

From the Hikikomori route, it seems clear that the Eye is not a figment of imagination, but Mari did actaully survive the fall and suffocated. Basil’s line about seeing something behind Omori/Sunny suggests this in the Normal Route, and it’s further cemented in the Hikikomori Route where Omori’s fear of drowning is tied to suffocation. In the same area you see the jump rope, used accidentally to suffocate a still living Mari.

Of note, when Sunny loses an eye in the good ending, it’s the right eye, the one Mari was looking at him with. It seems to symbolize him losing/overcoming that guilt.

Basil’s something is seen less frequently, though it’s seen in both routes. Basil acknowledges it directly to Omori. It takes a different shape, seeming to be based on Mari’s head as they carried her outside or as the lay on the floor, a lifeless head with messy hair falling in all directions. The Mouth of his Something appears to be literally swallowing him while Omori’s Something mostly watches him. It could be why Basil kills himself without intervention while Omori will only kill himself if the player does something to cause it. Basil dies in most endings but Omori only in one (that has two ways to trigger).

Red Knife & Color Red

The Red Knife seems to be related to Sunny’s fantasies of the knife and suicidal ideation. The description says “you can see something in the blade”, almost certainly meaning SOMETHING, the eye monster. It’s red color is probably due to the Knife endings where Sunny stabs himself for real and the knife of course turns red.

The general use of Red seems related to this suicidal ideation as well. Sunny says he feels drawn to the ominous red light outside the windows in the nightmare sequences. This maps to blood/suicide as sunny is drawn to stabbing himself as well. Rarely the Red manifests in headspace as well like the red grate with a Black Space secret in Sweetheart’s Castle.

You can see the Red in a secret in the Castle’s Keeper room that’s different based on which route you get.


The cracks the Keys leave behind are literal cracks in Sunny’s fantasy. Inspect the cracks—sometimes there are story-related scenes that will play when inspected. These scenes are missable. They’re literally the truth briefly breaking through the fantasy.

Basil’s Flowers

The flower patch south of the Stump has flowers, one matching each of your friends, Basil will explain these when you first visit his house. The wilting flowers represent your wilting friendships and memories of those friends over time.

You have to constantly refresh those memories and rekindle those friendships, or they’ll die like a flower. Take it from an adult, this part of the game is completely real. Talk to your friends. Don’t wait for them to text first, don’t be afraid to call them.

Watering the flowers gives characters permanent Hearts,  After a certain point in the story, they will not come back to life when watered. If you water them at least 3 times (not sure if this is 3 visits, or just 3 flowers), you will get an extra scene at the very end of the Good Ending in normal route.

Ending Spoilers
The hands at countless points in the game are symbolic of Omori shoving Mari away—and down the stairs.

Oddly most hands in the game seem to be reaching not pushing. Perhaps as a manifestation of regret or desire to touch Mari again. There is a scene shown where Mari is reaching out to Omori underwater, possibly symbolic of a real event where Mari saved him from drowning. When you reach into one of the holes left by keys, you feel someone holding your hand, probably Mari.

When you let in Mari’s Ghost in the first Real World segment, she does not have arms but empty sleeves. Her neck is also broken.

Ending Spoilers
The violin represents the broken emotions between Sunny and Mari, as well as Mari’s murder. Sunny smashed his violin, throwing it down the stairs causing Mari to yell at him. In a heated argument, Omori shoved Mari, with a bad leg, down the stairs.

Sunny and Basil faked a hanging for Mari, who either died falling down the stairs, or wasn’t dead and died for real from the staged hanging. The Violin is always “buried” in Headspace,

Black Box
Ending Spoilers

Exists in the Backer Demo but not the final game that I have seen.  The Black Box contained a piece of Sheet Music, suggesting the Violin in the final game. It’s likely this iteration of Headspace ended after Omori/Sunny failed to reconcile or face their memories.

The fact that Omori’s hidden memories were buried in a barn, where the Black Box is opened, is mentioned in Deeper Well, suggesting the Demo is a canon, earlier loop of Headspace.


The picnics are symbolic of all those picnics the friends had (as shown in Memory Lane). They’re an idealized moment in time recreated endlessly in Headspace to keep Omori enjoying himself and remembering Mari as she used to be.

Would you like to have a picnic with Mari?

Photo Book

The photobook is a literal interpretation of Sunny’s memories. That IS what photobooks are for after all. Notice the Headspace version has the same exaggerated unreal colors of Headspace, while the real version has real colors.

There are three photobooks, counting the headspace version separately.

Ending Spoilers
The second photobook found in the Normal Route is not a literal photobook, but a representation of Sunny’s traumatic memory of killing his sister, dragging her body to bed, then carrying her outside with Basil to fake her death.

Everything is going to be okay.

Memory Lane

Surely I don’t need to explain such shockingly blunt symbolism, but if you save on the highway in the Normal Ending where you revisit Sunny’s memories, you’ll notice it’s literally called Memory Lane.

Of course, the entire game is about memory.


Per the photo descriptions, the violin practice was killing Sunny’s fingers, hence the severed finger visuals in several late parts of the game.

Big Strong Tree
Ending Spoilers
This seemingly joke enemy in Vast Forest is probably a representation of the tree Mari was hung from. It’s extremely difficult to defeat especially when first encountered, seeming to echo the mini-blackspace event where Omori’s father asks “why won’t it fall down”.
Mirrors and Tentacles

I don’t know, but it seems like the Hikikomori Route will answer this.

Everything Is Going To Be Okay
Ending Spoilers
This is something Basil told Sunny after he killed Mari. In the intro we see Basil and Sunny together after the words Everything Is Going To Be Okay are shown on screen, then he appears in White Space trying to repress his memories.

The words appear several times in the Normal Route endings, most notably in the Energy Bar during the fight against Basil. It’s likely Sunny harbors resentment against Basil for his reassuring words as things have very much not been okay for him. The datamined descriptions for the OTHER photobook confirm they’re basil’s words.

A box in Hikikomori Route Blackspace 2 contains the cries of your mother reassuring you “We’ll protect you, everything is going to be okay” as well.

Everything is going to be okay.

The Favorite, The Oldest, and The Wisest

There are 3 entities the Coral Branch Tree tells you existed before Headspace existed in it’s current state. Here’s the transcript itself:

Late Game Spoilers

Before this world was created, there existed three great creatures… the oldest, the wisest, and the favorite.

The oldest is alive, but not the same as he once was. Age has removed his conscience and he has evolved into a parasite within himself. He lives here, just beyond this cavern.

The wisest, against her reason, committed an act that opposed the DREAMER’s will. It is an act that is not even known to me. As a result, she was stripped of her wisdom and banished to isolation… a special prison somewhere deep, deep down.

The last and favorite, the BIG YELLOW CAT, was chosen to watch over the DREAMER’s most precious room. He remains the DREAMER’s favorite even to this day… watching diligently… waiting for something to happen.

The wisest is Abbi, hidden in The Abyss. She’s the most mysterious and hypothesized to be an imaginary friend of Sunny’s, hidden presumably for knowing about Mari’s Death. Whatever she is she existed before the current state of Head Space and was cast down into The Abyss, but clearly has enough influence over Sunny to manifest as the little tentacles. Deeper Well is where memories are hidden/repressed, and The Abyss is adjacent to it and seems to serve a similar purpose.

The oldest is, oddly, Humphrey himself. Humphrey is revealed in the Hikikomori Route to be a kid’s book in Sunny’s past. He seems the most literal of these three and is probably just something that stuck with Sunny as a kid for unknown reasons. His bizarre and malicious state seems to be a clear example of the progressive downward spiral of Sunny’s mental worlds. Note the progressively darker tones (in both color and theme) between Vast Forest, Otherworld, Pyrefly Forest, Deep Well, and Humphrey.

The favorite is the big yellow cat, based on the cat playground equipment in his childhood playground, though a similar cat exists also in the treehouse. If you check the cat in the Real World he notes how it “seemed bigger” when he was young. It seems to represent safe, happy memories before any bad things happened in his life.
