Heck, I will take early 2000s fake anime over this, sometimes they indeed did make a gem(Avatar, Ben10 was fine as well). I doubt any of these melanin """manga""" are any good.

Dear God no, let's not return to the Kappa Mikey era.

And can a "manga" with a female protagonist really be a "shounen" if the genre is marketed towards boys?

Absolutely. Take Fairy Tail for example, where the female lead is the star and the male lead is her sidekick. I seriously doubt that this comic is actually targeted towards the interests of young men though, and it is almost certainly a halfassed attempt to redefine their interests instead.
