I dug into the story behind the TikTok user Sulkaeda who was used as a reference at the very beginning of this shitshow. She posted her video about her friend, Spoopyscaryaliens, and their experience with Pyro on May 9 2019, making her the first person to bring up Pyro's weird behavior with minors.
Spoopyscaryaliens is an artist who drew fanart of Pyrocynical in 2016. Pyro reached out to them around August 13 2016 after seeing fanart Spoopy drew of Pyro's fox character curled up with a dakimakura of NFKRZ's character. In the very first messages Pyro sent Spoopy he said "IT'S NOT EVEN THICC." Pyro then immediately asked Spoopy their age. Spoopy said "I'm 15." Pyro would be 19 around this time.

8 days later on August 21 Spoopy posted dakimakura style fanart of Pyro's fox character being noticeably chubby and wearing nothing but underwear. In the description they said it's "Pyro approved." Prior to this all of Spoopy's fan art of Pyro had his character being thin and none are this lewd.
Later in DMs with Sulkaeda Spoopy said Pyro "demanded" they draw fat fetish art for him. The daki piece seems to be the only instance of this though, at least publicly.


So Pyro was asking someone he knew was underage to draw lewd borderline fetish art for him and then, according to Sulkaeda, kept pushing for more and more extreme fat fetish art.
This also proves Pyro has no issue asking people's age before starting fetish shit with them.
This behavior of "jokingly / innocently" bringing up his fat fetish with minors also matches what I saw in the other accusers's cases. With
AbortionASMR he sent her a sketch of a fat furry, something that could be brushed off as a joke if it didn't go over well, and when she responded with "cute" he jumped into asking if she liked "thicc fur stuff." With Ivory he sent him a drawing of a character that was fat but not obscenely so, a character that wouldn't be out of place in a children's book, and when Ivory responded positively he then ramped it up to the extreme fat fetishism.


After everything with Ivory blew up Sulkaeda put out a second TikTok video clarifying that she and Spoopy weren't hurt and they just see it as a funny story.
