YOTSUBA KOIWAI - Yotsuba Koiwai, or $YOTSUBA as she's known on 4chan, is the ultimate symbol of internet freedom and rebellion. This little green-haired girl represents everything that 4chan stands for: unfiltered expression, anti-establishment values, and a complete disregard for political correctness. She's the perfect mascot for a website that prides itself on being the wild west of the internet, where anything goes and nothing is off-limits.
