I found some pictures that looks like from Shoujo manga, it have fight scenes like in martial arts. Some in the wrestling ring, some street fighting, some boxing. Any idea what Shoujo Manga have that scenes? I'll show you some pictures in Discord or X, if you want.

Karate Shoukoushi Kohinata Minoru?

Wild guess.

That's not a Shoujo manga, sorry.

You would be right. I mixed up shoujo and josei. I apologize.

By the way, shounen, shoujo, josei and sienen are target demographics, not dedicated art styles. You will find that some non-shoujo manga have the art style shoujo is most well known for.

Can I asking about H related manga in the forum?

I believe 'H' as in ecchi is OK but if you want to ask about an actual hentai, then there is an adult (r-18) forum.
