Hello, you can go to pool party location in city map. She should have shown up when you bought the bikini.
I know that, and I tried it already. Yuri doesn't seem to work, but the Mio and June do
We have noticed there's a bug where you have to buy both Yuri and June's bikini to access her scene. We will release a fixed version in a few days. Sorry for the inconvenience.
