Hiyori Ibara is a virtual YouTuber in Japan.
This is a paper craft of her made by S.V pepakura designer.
Ibara Hiyori (????) is a female Japanese Virtual YouTuber, a virtual employee of Ibaraki Prefecture’s public relations division, and the first effort from a Japanese prefecture to be represented by a VTuber.
She debuted back on 2/8/2018. You can watch her YouTube here
As for her paper craft template, you need to have a twitter account and direct message S.V himself requesting the template.
updated : This model production is closed / no longer distributed
I am not sure if the paper craft proof you need to give him is from his design or any template you made before. But to be sure just give him a finish work of his designs.
This is in order to avoid people distributing his paper craft without his permission or selling it.
