This mode is a reference to Metal Gear Solid V: The Phantom Pain. Press P to activate this mode. It cannot be deactivated until the game is reset or the day is over. Once pressed, Yandere-chan will resemble the main character Punished "Venom" Snake. She will wear a torn-up version of the default uniform, a tan-colored scarf, a black eyepatch on her right eye, a red bionic left arm, a scar on her left eye, a black protrusion from her forehead, a black glove on her right hand, and a cigar in her mouth.
The easter egg's skin texture will break if Yandere-chan wears gloves.

- The game's warning referred to this mode, saying that the game contained "STANDING ON THE EDGE". This warning was later removed because YandereDev said that it was "cringey".
- The song, "Nuclear" by Mike Oldfield used to play in this mode. This music was replaced as to not be copyrighted.
