The School Outfit color is a Unit Color cosmetic that was first introduced during the School Crashers event in 2018. Colors for additional characters were added to the set during the School Crashers (2020 Rerun) and School Crashers (2022 Rerun) events. The color is seasonal as there is no means to unlock it outside of an event.
No current unlock method. (Seasonal Unlock)
- Even though the School Outfit color is unlocked for all characters it is available to upon fulfilling the requirement, it is not automatically available to use for any new characters that receive the color in future updates, even if the player has already unlocked it. In other words, the unlock method must be performed again to unlock the color for the new characters. Therefore, this cosmetic counts as having an individual unlock type.
- During the School Crashers event, the player could unlock the School Outfit color by collecting all 4 of NoName's body parts from Minigame panels, thereby meeting the event goal. This unlocked the color for every character that it was available to at the time, that being Marc, Peat, Sora, and Sora (Military).
- During the School Crashers (2020 Rerun) event, the School Outfit color was unlocked the same way as in the original event. However, collecting every body part this time unlocked additional colors for Miusaki, Ceoreparque, Alte, Tsih, Mira, and Aru (Scramble) as well as the original four. In Version 2.8.1, a School Outfit color was also added for Aru, unlocked in the same way.
- During the School Crashers (2022 Rerun) event, the School Outfit color was unlocked the same way as in the original event. However, collecting every body part this time unlocked additional colors for Yuuki, Islay, Marc (Pilot), Alicianrone, Arnelle, and Lone Rider as well as the original eleven.
