the more technical it is the better, so somethign like berserk where the guy is just using a sword is not what I am lookign for, but it is still preferable to stuff that has teh mc shooting lasers of his sword. something like holyland is ideal, so I guess something technical with kendo can also work.

There's a korean webtoon that's exactly about fencing. I don't remember if it was very good, but if you want you can check it out: Attaque

try Gamaran

thanks for the suggestions, will look up to both of them (I just hope the korean webmanga does not crash my tablet like they use to do)
