This is the last and hardest of the three endings to get, and is the most well known.
Sabitsuki is shown outside on her rooftop. Then a gas-mask maid will appear, and hold up a chainsaw. Sabitsuki then changes slightly - she smiles evilly and laughs like a Kaibutsu as she charges towards the maid. Then the screen cuts to black as a scream is heard, and then Sabitsuki is shown lying in a pool of blood, with her legs cut off, being watched by the maid. Then Sabitsuki becomes still.
The maid carries Sabitsuki away, and then she is shown standing up - without her legs - on two patches of blood while two black-haired girls stand around.
Pressing "ENTER" causes red static to envelop the screen and the Kaibutsu laugh plays. Then Sabitsuki is shown walking past various NPCs of the game, wearing her headphones. At the end of the walk, as the credits come on, the maid bows to Sabitsuki and the screen fades to black for the last time.
Become Rust, then collect the three Empty Boxes. Go into .flow and an elevator will be there in the place of the computer; take it. Then take the very last level of the game. Afterwards, go outside and the ending will play.
- By fans, this ending is considered to be a "happy ending."
