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.
