Experimental, very random and contradictory . There was a page where "neoism is all about sex", then another where the narrator "gave up sex [...] and is now a neoist" . It's either the state of accepting one's own religion or adopting whatever religion one's interested in, even a fictional or deviant one, and making it anonymous.
It's a kind of negativist and Zen view on the world. Once, I had to do a tarot tirage (I do them to make a rubric for a radio podcast) for someone similar, who was litterally asking "why do ?", and Eris responded to her "what the ! stop giving up on Akari, notice her" ! So there's some chance that Neoism is not Erisian .
Some of them seemed to actually call themselves Cantsin in an intent to become anonymous, kinda reckless giving all the problems Argéniums would make of such behavior.
