>>52078032OP here. It's not about her design, but her character in the game.
I didn't care about her one bit until I played Scarlet, and now she's my favourite Poké girl. I am obsessed with her.
I just love how she acts, how she gets protective over the player. That thing she does with her hair when she loses a battle against you kills me. She just makes me feel all warm inside. No other Poké girl has done that for me.
