Update on the Filian situation:
[
a]
TL;DR there are talks between Goodsmile, Filian and the artist, Jingo. The last paragraphs show that Jingo is heavily protective of his works because it would open a precedent for free copyright or future issues, having to deal with everyone that wants to make merch out of his Booth models.
I don't think this one would sell out for money considering his reasoning to maintain all Booth customers under reign, but Filian could bite the bullet and offer 30K anyway.
