Oh yes, that individual is very... special, let's put it this way. Terminal coomer who tried to get in the pants of a lewd cosplayer, extremely overconfident in his artistic abilities, blew tons of money arranging contests trying to get on a radar for Yostar. Threatened people in the past with copyright lawsuits for using his "designs" (it didn't go anywhere) and iirc is vietnamese.
Edit: Btw, he thinks that even posting links to his twitter posts is grounds for copyright lawsuit, let alone a screenshot. Because you are "stealing my engagement on social media" and bitched about before. So I will not be surprised a bit if he registers here just to send Proctor a DM asking to remove it
