well from what I've seen in other Imaichi cross over images she's either compared to Azusa from K-on or Miku vrom Vocaloid but with a different color scheme and clothing. And we all know at one poinr BRS was compaired to Miku. So now Imaichi is being compared to BRS as well.
Joke here? Dead Master must be color blind not to see the difference. I guess.
