The Abyss is a location in OMORI. It is an optional area exclusive to the Hikikomori Route that can be accessed after saving Basil in the Hikikomori Route and talking to the Hitchhiker.


The Abyss is comprised of seven levels, each structured in maze-like patterns and connected by ladders. Only the top layer can be accessed initially: Collecting every Hangman letter is a requirement to open the path to the deeper levels.

As Omori travels deeper into the Abyss, enemies are swapped out with several Something variants. Additionally, in the sixth level, multiple skeletons can be found that are very heavily implied to be past versions of the main group, excluding Omori.

In the seventh level, the player can find Abbi, who immediately challenges the team. Upon her defeat, she will beg Omori and the Dreamer for mercy. If granted, revisiting the tentacles scattered across Headspace will prompt Abbi to offer the team very powerful weapons and accessories as gifts, including Omori's strongest weapon, the Red Knife.

If killed, Omori will gain Abbi's Eye and will be unable to receive the tentacle gifts.

Regardless of however Abbi is dealt with, walking to the far right of her arena will teleport Omori into the Weathervane Area of Black Space. This will only work once.


Before the creation of Headspace, there existed three great creatures: the oldest, the wisest, and the favorite. The wisest, implied to be Abbi, committed "an act that opposed the Dreamer's will," and was subsequently punished by having her wisdom stripped, followed by banishment to the bottom of the Abyss.

Due to the Abyss having a direct, barely hidden link to Black Space, as well as Something-esque enemies bleeding through the lower levels, it is strongly implied that the Abyss is closely related to, or is a part of, Black Space.


  • The Abyss may not be revisited if the player decides to kill Abbi.
  • Walking right after defeating Abbi (either sparing or killing her) will eventually warp you to the Weathervane Area.
  • The Static Void map has code that implies that the Weathervane Area was not the original warp destination.
  • Killing Abbi will make the room transition from the final room to the room above slightly longer and teleport the player straight to the first room of the Abyss.
