and there are no doubt tons of statue fags that kept complaining about joints that gsc sadly took seriously, because really a lot of the people that dont normally buy figmas and just does it for their generic vtuber of choice would be better off getting a statue and frankly figma arent too far off in price to some of them nowadays
