Thank you! Can you please explain this "miku" character/meme ? is it some b_sky maskot?

It began with a brazilian musician making a song using Miku and mixing it with brazilian funk. It then gained popularity and people started drawing Miku as a brazilian, which then lead to one of the illustrations becoming a hit on twitter.

Shes a vocal software from the early 2010's!!!! She's like Japan's version of Barbie but u make her sing
