I was quite suprised to see Riho performing in Babymetal since it's well known that she's more into Hip Hop and R'n'B (she's a Britney Spears fan after all) but it's good news since we can see her again and she seems to have a lot of fun on stage Plus, she has the chance to travel that way
I'm not too fond of Babymetal but if she's part of the team for the live in Paris, I'll try to attend the show. To be able to see Riho on stage would be pure magic!
