In degeneracy news, Not Ollie now has a fursona with a sussy name (Pronika)
I get the feeling that this girl is severely underfucked
Something else I saw, was this user:
He's a hardcore Ollie Fan, that on its own isn't bad or anything, but he also has a small little side hustle
https://twitter.com/RrazzNSFW (Very NSFW and explicit profile)
Here he posts tons of Koikatsu porn, mostly of Ollie
What I do think is interesting is that he uses some kind of Self-insert male model in Koikatsu, and then he has seggs with both Ollie and Suu (her RM)
He also uses that self-insert Koikatsu model on his SFW account, there he does wholesome things with her, like going on a date or just cuddling and stuff like that. Here too, he uses both of Ollies personas.
So it's definitely not some guy who has the hots for a Zombie, it's very much about the person behind it.
These are mostly just my first few observations, but I wanted to go more in-depth later on another day, because he does seem like an interesting specimen of an ultra parasocial person.
