Shigure Ui × Mezzo Piano Colab situation

Okay so Mezzo piano are like a children brand and they had the great idea of collaborating with this vtuber the problem is…Shigure Ui is a whole ass pedophile, shes a open lolicon and has made really weird remarks about high school girls. Yall might recognise her from the song she made I’ll post the picture in the replies. Genuinely what were they thinking??? Thankfully it’s now cancelled but wtf
