Mari is the older sister of Omori in OMORI. She's often spoken of as being kind and gentle, and plays a sisterly role in the friend group with Omori, 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. It is also shown that she is a perfectionist, spending hours at a time practicing the same piano piece over and over again.

OMORI
OMORI is the titular deuteragonist in OMORI. OMORI can be controlled by the player during the night, where WHITE SPACE can be explored. When OMORI is in the lead, he can cut down obstacles with his knife.
