Story & Plot

This page details the story and the plot of Omori.

Story

OMORI is a psychological horror RPG about a boy named Sunny who overcomes the death (and his involvement in it) of his older sister, Mari.
At night, Sunny enters Headspace, a fantasy like dream world that was created to repress the death of his sister as much as possible. When Sunny is asleep, he takes the form of Omori, an alter ago of Sunny.

Prior to the events of the game, Sunny and Mari grew up in Faraway Town with their next door neighbors, Kel and Hero. The four of them meet Aubrey on the side of the road after she loses her shoe. Aubrey then introduces Basil to the group.

At the start of the game, one of his former friends Basil, goes missing in Head Space and so Omori, an alter ego of Sunny of some sorts, and his former, now imaginary friends, Kel, Hero and Aubrey, go out to find him.
Every night ends with Omori being forcefully thrown into White Space by Something, the major antagonistic force in the game.

At day, Sunny moves around in Faraway Town. At the beginning of the game it is revealed that he will move in about 4 days. Kel, one of his former friends, reached out to him and spends his last few days in Faraway Town with him.
In tandem with both the night and day segments, the player must find out what has happened to Sunny, his older sister, and his friends.
