I was checking Doki's website for subbed Pripara episodes. I came across this news in a comment.
Seems like Pripara's ending got a lot of complaints for showing girls in swimsuits. According to them, such scenes are "unneccessary" in a children anime. That's the real reason why Sophie's picture was "fixed" with the new one in latest episode.
I'm not sure about how to react. What do you think?
