Hey, SUNNY! It's MARI! I'm finally back home, but I forgot my keys... Could you open the door for me? ![]() |
— MARI during the prompt that initiates HELLMARI's first appearance |
HELLMARI is a mysterious character and NPC in OMORI. She is a demonic-looking version of MARI, which symbolizes how SUNNY remembers and thinks MARI is that OMORI and SUNNY frequently encounter throughout the game.
PROFILE
APPEARANCE
There are three versions of HELLMARI that appear in different locations throughout OMORI. Like many other horror elements of the game, she appears much more realistic than most of the game's contents, likely to scare the player more due to how out-of-place she looks.
DEFAULT
The version of HELLMARI that appears in SUNNY'S HOUSE and RED SPACE is tinted blue, likely due to it being nighttime whenever she appears in these areas. She has a large, gaping mouth, and her eyes are replaced with empty sockets; she lacks a nose as well. Her head appears elongated and skull-shaped, and she has long, stringy black hair that extends past her visible sprite. Her head is bent at a sharp angle and resembles a person's broken neck after they are hung. She is wearing a white dress, similar to the one MARI's spirit wears and what MARI was wearing when she was hung from the tree.
BLACK SPACE
This version of HELLMARI mostly appears in BLACK SPACE. Unlike the HELLMARI that appears in SUNNY'S HOUSE and RED SPACE, only her head is seen and she has a monochromatic color scheme. Her head bears a heavy resemblance to the blue HELLMARI, but she has less hair that is more stringy and rows of sharp teeth can be seen inside her mouth.
MANNEQUIN MARI
This version of HELLMARI appears in BLACK SPACE, mostly in the HAUNTED TREES HANGING MAZE and TWOSIDE. She has a normal color scheme which matches that of the real MARI. She has an elongated neck and she appears to be smiling. When she touches OMORI, however, her face will warp into a similar gaping-mouth expression to the other versions of HELLMARI and the colors of her sprite will become much more saturated.
STORY
PROLOGUE
After SUNNY throws up in his bathroom, a knocking on the front door can be heard. If SUNNY goes to check the door, MARI will be outside, saying that she cannot get into the house due to forgetting her keys. The player will then get a prompt to either open the door or ignore her. If the player chooses to open the door, a short cutscene will play in which SUNNY slightly opens the door, HELLMARI being visible but mostly obscured.
The door will then shut suddenly and HELLMARI's full appearance will quickly flash on screen in a jumpscare. After this, the next time the player checks the bathroom mirror at night, HELLMARI will be seen standing behind SUNNY. Additionally, if the WTF VALUE is greater than or equal to 6, HELLMARI will appear on the bed in MOM'S ROOM for 666 frames before vanishing.
If the player chooses to ignore MARI, she will remark that she's cold and HELLMARI will not appear. Ignoring MARI at the door will not trigger the OMORI ROUTE.
TWO-ONE DAY(S) LEFT
Collecting the ninth KEY and entering the hole it leaves behind will play a cutscene where OMORI is falling underwater, and seems to fall into HELLMARI's mouth.

Before entering BLACK SPACE, a coffin with MARI inside will be at the top of a long staircase. Walking close to it will cause MARI to transform into HELLMARI and lunge at OMORI as a jumpscare before vanishing, the coffin being replaced by the door to BLACK SPACE.
In STATIC WORLD, one of the area's objects is a high-contrast image of the mannequin HELLMARI's head, with her body cropped to resemble SOMETHING. OMORI can walk on it, but will be heavily slowed down while doing so.
In THE NEIGHBORHOOD, interacting with a specific house causes the mannequin version of HELLMARI to briefly appear while making a screeching noise.
The secret area MARI IS HOME, which can be entered through FOREST OF STUMPS, contains an event similar to the first night sequence in which MARI is at a door in a crawlspace under the piano room. The player can either open it for her or ignore her. This time, however, if the player ignores her, she will open the door herself and HELLMARI will chase OMORI down the hallway. If the player opens the door, HELLMARI will not appear.
In TWOSIDE, smashing all of the mirrors will cause a distorted version of the mannequin HELLMARI to appear and chase OMORI. Touching her will cause a short jumpscare before she disappears.
On the final page of the sketchbook in BLACK SPACE, HELLMARI can be seen along with SOMETHING.
SUNNY ROUTE
During the TRUTH segment, a small version of HELLMARI can be seen wandering in the darkness around the recital stage area. She becomes more visible if SUNNY gets close or picks up a photo.
On the ONE DAY LEFT segment, HELLMARI makes three appearances during the fight with OMORI: the background for the fourth phase of the battle adds a close-up of her head, the background for the fifth phase adds several blurry mannequin HELLMARIS, and OMORI's ERASE attack during the fifth phase shows a red HELLMARI.
OMORI ROUTE
HELLMARI makes multiple appearances in BLACK SPACE 2 that cannot be accessed in the SUNNY ROUTE. These appearances are exclusive to the ONE DAY LEFT segment.
In the BLACK PLAYGROUND, when interacting with the OMORI head on the far left of the area, this will take the player to a facsimile of SUNNY's bedroom. However, it is rather darkened with a monochrome color scheme. SUNNY can be found sleeping in his bed with HELLMARI hovering over his head.
In the CORRUPTED JUNKYARD, HELLMARI's face can be seen in one of the black areas.
In the HAUNTED TREES HANGING MAZE, touching the floating pieces of TOAST will transport OMORI to another part of the maze filled with hanged MARIS that drain OMORI's HP. After a few seconds, these hanged MARIS will transform into mannequin HELLMARIS. There is also a ladder in the center of the HAUNTED TREES HANGING MAZE that descends down many rooms until it reaches the bottom: a pitch-black room where a large sprite of HELLMARI's face appears and follows OMORI.
If SUNNY has opened the door for MARI in the PROLOGUE, this causes various events to occur. During the night of ONE DAY LEFT, when SUNNY is trying to go down the stairs, HELLMARI appears at the bottom and quickly lunges at SUNNY. The radiance from the PIANO ROOM will become bright red after the jumpscare. She also appears in the before-bed animations when SUNNY chooses to sleep until MOVING DAY.

TRIVIA

- In the OMORI Preorder Promo, HELLMARI makes a brief appearance when MARI is shown glitching onscreen at 0:28. In addition, upon close inspection, the text "I love you" and "143" can be seen as well.
- In the game's files, HELLMARI is referred as "horror_mari", "bs_mari", and "mannequin_mari".
- HELLMARI was originally planned to have an encounter on the morning of TWO DAYS LEFT. This scrapped event would only occur if SUNNY opened the door for MARI during the PROLOGUE.

- If SUNNY opened the door for MARI during the PROLOGUE, on ONE DAY LEFT of the OMORI ROUTE, HELLMARI's face can briefly appear in the living room, MOM'S ROOM and the dining room at night before each one vanishes after a short moment. It is quite difficult to recognize them in the game as the original sprite is nearly transparent.
- It is also notable that all the three locations have a connection to family photos. The faces in MOM'S ROOM and the dining room are close to some family photos, and the one in the living room appears at where the large family photo was.
- During the simulated MARI's boss fight in the BOSS RUSH, HELLMARI briefly appears via a quick jumpscare to automatically end the fight.
- In the game's files, HELLMARI was originally meant to appear when MARI herself is defeated. However, the defeat animation ends up becoming unused as lowering MARI's heart down to 20% or lower will automatically transition into the HANGING BODY phase of the fight.
- If one were to open up the PHOTO FRAME map, the area where the F KEY can be found, half of HELLMARI's face can be seen on the very top of the map. Because of the collision applied on the wall in the end of the hallway, the face can't be seen in-game.
- Prior to version 1.0.5 of the game, if OMORI chose to stab himself in the ROOM WITH HELLMARI, HELLMARI's face would follow him in the overworld until he returned back to the area she was encountered in. This bug has since been fixed.
