Ok so apparently him not being able to punch properly as a girl is sexism?
Even my punch is weaker than my elder brother's, but I'm stronger than one of my male friends.... I think it's completely normal that he is a bit weaker in physical strength in his girl form. Not every girl is strong just like not every girl is weak. Same goes for guys.

I'm failing to see where the manga is sexist? Like that guy was sexist and obviously not a good person.
But is the manga sexist? It's a character that was sexist, and it was not applauded either.
