Empty Boxes

The Empty Boxes are effect-like obtainables in .flow. There are three of them, and they can be collected only by Rust, in the areas that are inaccessible to Sabitsuki. These items are necessary to unlock the True Ending. Without them the player will get the Maid Ending.


The Demon (鬼) is placed in the Back Ward. To get this item, the player has to go to the Parade Ward, and interact with a bloody hole in the wall. This will teleport Rust to an area identical to the Blood, Pus, Rust room, but this time Rust can go through the door, and arrive at a Flesh Walls area.

This area goes similar to the Dying Girls Event, but here, the black-haired girls blocking the path will quickly decay, allowing the player to go to the next room without any effort. The final area contains a giant black-haired girl, with her stomach cut vertically, and by interacting with it the player will get the Demon item.

Rust will be teleported back to the Parade Ward afterwards, and the bloody hole will disappear.

  • These items are named after the switches that they trigger and rooms that contain them.
  • They still show the 'get' message when collected, even though the message box itself is empty.


  • These items may be related to some of the most traumatic experiences Sabitsuki has had.
