Gisokuko (義足子) is a monochrome girl found in the building at the sea. She has mechanical legs much like those Sabitsuki receives from the Machine effect.

If killed with the Iron Pipe, she stays dead even if the player wakes up. Her dead body remains in that room and can be beaten more. If she is hit with the pipe the second time, she makes a different, quieter moan, and makes no other noises after that.

This girl is absent when her room is visited by Rust.


  • She does not have a name in the game files or code, but Japanese fans call her "義足子". "義足" means "artificial legs" and "子" is often used at the end of female names.
  • There is a black-haired child with mechanical legs in the Hospital. It is unknown if these two characters are the same.
