This mode is a reference to Galo Sengen, a meme and a pun of Super Saiyans and the style of Gyaruo combined; it is also based on a music video of the same name. Press G to activate this mode. It cannot be deactivated until the game is reset or the day ends. Once pressed, Ayano Aishi will have tanned skin, gold bracelets, sunglasses, and Super Saiyan hair.
Galo Mode is mostly cosmetic, but the player has a special ability in this mode. If the player presses the Left Control key, Ayano will "power up" and charge her energy like a Super Saiyan. Ayano's reputation will be affected if any student sees her powering up, an automatic Game Over will occur if Senpai witnesses her, and the teacher will send Ayano to the guidance counselor.
- If Ayano puts on gloves and then takes them off, her skin will not be tanned.
- Galo Mode was implemented in the May 3rd, 2015 Build.
- Press D to disable the copyrighted music.
- The game's warning referred to this mode, saying that this game contained "fake tans". This warning was later removed because YandereDev said that it was "cringey".
