Found this on the Baraag on a post simply saying "Collab".
Also, they have 1.2K followers on there, which is actually pretty impressive. Not massive or anything, but definitely not a nobody either.
Tried to see if I could find something interesting in their Follows, but nothing out of note, beside them only following 4 accounts, one being basically just a Japanese guy's blog/instagram.
Oh, also this was the only image I found of Hex Manic on there.
