>>11639840anon, the fact reimu and nina are able to speak about their talks with their manager and the fact the manager themselves APPROVED the stream is proof enough its not a holo thing.
Nijisaniji managers are super flexible with streams as long as the idea you pitch them looks viable enough, (squid game cookies petra was also a pitch) and so far nijisanji has had tons of freedom on their streaming content, notice how manager stopped pushing minecraft to nijiEN or how much freedom selen has to collab apex with almost anyone she wants? niji managers are very competent.
