Rust Menu

The Rust menu is one of the hidden menu types. It is styled after the rust aspect of .flow.


To unlock this menu, the player has to raise their Erosion Counter to at least 100 points, then interact with little Sabitsuki in the Back Ward.

To equip it, the player has to interact with the second Kaibutsu behind the counter in the entrance of the School. This Kaibutsu appears only if the player has learned at least one hidden menu type.


  • This is the only hidden menu type obtainable by Rust.
