some korean shoujo mangas have more realistic fighting because of the jangs, hell, hot blooded woman form the romance topic has got more interesting fights than the typical shounen.
Actually, I decided to give Holyland a chance and continued reading it. Heh, it actually becomes better.
now I m reading Historys Strongest Disciple Tatakae Ryozanpaku , it's very similar to kenichi so it feels like I am rereading that one instead.
to me the most realistic martial art manga is Shura No Mon, the drawing is not that great but really captured the intense of the motions.
