>>43640853I'd like to see it done subtlety. You show up at her gym but all of the furisode girls are scrambling to keep up with all the work at the gym. You get to the end and fight "Valerie" but she's noticeably inexperienced. If you do some exploring, you can find a pokemon in a dress that the furisode girls are caring for.
That's how I'd like to see it presented, but I still have no idea what pokemon she would turn into.
