MARI is a major supporting character in OMORI. She is the older sister of OMORI in HEADSPACE, and SUNNY's older sister in the REAL WORLD. Her presence as a whole also serves as one of the major driving forces behind the game's story.
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.

Cool thing is, she is now thicc. Now sitting with big breasts/thighs.
