Which is why immediately after release they got fubuki and a few others to tell people it’s not an anime, but also announced it’s an MV confusing people even more.
They didn’t need a weird name/brand/big announcement to tell people non-stream related hololive content was being produced. They should have just announced the projects when they were done by themselves.
