Mari

MARI has 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. She is 18

In the REAL WORLD, MARI had dark brown hair and 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 when MARI was younger, 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.
