Gyaru Harem Invasion
Artist: hishigata tomaru
The Sauce: Gyaru Harem Invasion
The funny numbers were removed for some reason, but there are other versions at least (and other places)
For context on who's who, before and in the pfp, if you didn't check the other bots, the order of characters go:
Reina (Crude Gyaru), Ayane (Devilish Gyaru), Lilia (Monotone Gyaru), Natsuki (Tanned Gyaru)
