>>72455296The obvious conclusion here is that she wasn't given the play button by the company, and would therefore get in trouble if she posted proof that it was at her home.
Clearly, she must have stolen it from Nijisanji headquarters while she was in Japan, and brought it back home when she returned! We thought Reimu was merely a ghost vtuber, but in fact she was a masterful phantom THIEF!
Or, y'know, she could've just made her own bootleg play button by ordering a spare for her PL channel and having youtube write "Reimu Endou" on it. It'd be a clever way to circumvent Niji's restrictions, don't you think?
