I thought Cirno was more than one person, like a group of friends who used the name to troll with set guidelines, or a franchise.
When I asked other anons about this, some assumed he was a robot.
He really was on all the time, I seriously wondered how he could do anything else other than post here. I mean it was obvious he didn't work or go to school, but I don't see how he could have watched anime or slept either.
I'm starting to think maybe he just stayed on 4chan too much and expired Korean Lan Party Style.
