smash ultimate isn't though
it's E 10+ at best

I hate this change. The reason Mythra was dressed in white entirely is that she's based on light or purity. She's the good person, and having her be dressed in white makes her the opposite of Malos, who dresses in dark, so dark thigh-highs doesn't really work. I understand that they had to give her the Bayonetta treatment because ESRB and CERO wouldn't be happy, but this ruins the whole point of one of the main character's motifs.
