>>35276175At first she seemed an interesting character as the spoiled daughter of a famous rider, with behaviors more typical of a teenager, her relationship with a young Ash seemed an interesting detail, but here is where everything went to hell, that could remain as a peculiarity, became all her development as a character "being a cute girl with a crush", you say but their performances? that was horrible, it was only her dancing with her living stuffed animals, it would have been exciting to make an analogy to the demanding world of Japanese idols, hours of practice, multiple disciplines to master (dance, singing, diction, choreography, acting, calligraphy, music , instrumentation, oratory) zero social life, the saturated competition, and the drama behind the curtain.
Well in short she is not the worst character in the series, but by far does not contribute anything (Yes a lot of characters have or had a crush in Ash, inclusive pokemon), as OP says "Imagine that you take away her crush in Ash, but without adding anything else" Honestly, what is left?
