I think someone is cosplaying Galna, Chima-chan?

I also think it's Chima chan

I think it’s more like silvia-chan ‘cause chima is too short to be the height galna was cosplayed as and silvia could portray galna better. Also, chima-chan is one of the people who welcomed the guest so meh. This is just what I thought though (〜￣△￣)〜
