I don’t watch any type of anime but if they made an anime about all the vocaloids, I would watch it

Same it would be so good but then again it would feel really weird, I felt really weird watching the animation mostly because I knew the Characters and there were Vocaloid posters in once scene which was like really trippy to me because when you think of Vocaloid you think of their voices and their Character designs not an anime. It's just like uncanny to me because I'm not used to that but there are some mangas out there and I've seen a few glimpse of them and just gives me a weird vibe.

Kagerou Project got his own anime and there are a few references in other anime too like Lucky Star or Himouto Umaru-chan (both just Miku but it's a start, lol)

Yeah I've watched both of those, pretty cool

There's also Go! Go! 575 Project, which includes Matcha and Azuki. Plus I've seen other references and spin-offs, like there was a spin-off of K-on using VOCALOID characters, and Miku has been in Baka to Test Shoukanjuu, as well as Hyouka along with Luka, Rin, and Len
