MARI - headspace Version

MARI is a teenage girl with long, straight hair and bangs. In HEADSPACE, she has dark hair and eyes which are stylized as purple. She wears what looks like a variation of a Japanese seifuku.

In the REAL WORLD, MARI had black hair, black eyes, and wore a purple jacket or sweater over a white dress. She wore purple shoes. Her appearance also influenced her HEADSPACE counterpart's appearance.

As a spirit, MARI looks slightly older than her HEADSPACE counterpart. Similarly to OMORI, she is completely black and white, and her eyes are black with white pupils. She also wears a long, white dress.

She's often spoken of as being kind and gentle, and plays a sisterly role in the friend group with SUNNY, HERO, KEL, AUBREY, and BASIL. Her first appearance shows she has a mischievous side, poking fun at KEL and AUBREY's mannerisms and afterwards teasing HERO. These traits are shared with her HEADSPACE counterpart.

Later in the game, it is also revealed she would pull pranks on HERO especially, such as putting bugs in his school desk. It is also shown that she was a perfectionist, spending hours at a time practicing the same piano piece over and over again.

Even after her death, her spirit form is shown to be forgiving towards SUNNY despite what he did to her. She also tries to help SUNNY forgive himself and reminds him to remember what's important. Despite knowing that her brother accidentally killed her in the past, MARI wishes for SUNNY to move on and live out his life without any regrets.

MARI is SUNNY's older sister. Both siblings are shown to dearly love and care for one another as shown throughout many flashbacks and photos from the PHOTO ALBUM. One demonstration of this dear love was when SUNNY accidentally fell into the FARAWAY PARK lake, and almost drowned. He was saved from drowning when MARI jumped in after him, rescuing and resuscitating him. After saving her brother, MARI collapsed and sobbed out of relief that SUNNY was okay. SUNNY's frustrations would eventually meet a tragic peak the day of the recital. After finding SUNNY's violin destroyed at the bottom of their house's stairs, MARI and SUNNY got in an argument. In the heat of the moment SUNNY pushed MARI down the stairs of their house, which tragically resulted in her death. This, along with the disguising of MARI's accidental death as a suicide, left SUNNY deeply depressed and paralyzed with guilt.

AUBREY was one of MARI's childhood friends. The two were very close, with both viewing the other as the sister they never had. MARI can be seen consoling AUBREY in one of SUNNY's memories. AUBREY and MARI spent a lot of time with each other, as well as their other friends, and even wanted to dye their hair together at some point - MARI's hair purple, and AUBREY's hair pink. This hair-dyeing would not come to be, as MARI tragically died before they could do anything.

In the years following MARI's death, AUBREY changed greatly. The reaction of their friend group to MARI's death as well as the estrangement of their friend group caused AUBREY to become deeply embittered. To AUBREY, it appeared as though none of her friends cared about MARI, as they outwardly didn't express any grief over MARI's death, and seemed to carry on without sentiment for MARI. Furthermore, none of her friends were there for her when she suffered more tragedy, such as her abandonment by her father.

BASIL was one of MARI's childhood friends, introduced to her after AUBREY invited him to join their friend group. MARI was greatly nurturing of BASIL. In addition to treating BASIL with the love and care she did the rest of the friend group, MARI purchased him his camera as well as his PHOTO ALBUM, and encouraged BASIL to pursue a hobby of photography. Both the camera and PHOTO ALBUM became highly valued treasures to BASIL, as he listened to her encouragement, using the camera to express himself and fill the PHOTO ALBUM with precious memories.

KEL was one of MARI's childhood friends.

Although KEL and MARI's relationship is the least explored in their friend group, it can be inferred that they cared for one another. MARI acted as a loving sister figure to KEL, making sure that he and the rest of their friends stayed safe and out of trouble. They were comfortable enough that MARI could tease KEL about his height in comparison to HERO's. Furthermore, as MARI and KEL were the only known members of their friend group to participate in sports, it's possible that they may have shared an interest in sports together.

HERO was one of MARI's childhood friends and next-door neighbors. As the two were the oldest in the friend group, MARI and HERO often took responsibility over their younger siblings and friends, watching over them when they fell asleep and making sure everyone was safe. It was strongly implied that they had mutual romantic feelings for one another: MARI and HERO often spent time together and greatly cared for each other, and on a number of occasions even rested together, such as during BASIL's birthday party.[9]

This is implied further by BASIL describing the two as a "match made in heaven"[10] and by SUNNY envisioning their HEADSPACE variants as being flirtatious with each other.[11][12][13] However, it seems that the two may have never publicly considered themselves to be a couple, as none of their friends or siblings described them to be dating. Whether this was because they didn't want to make MARI's dad upset[14] or because they were simply just friends, is unknown.
