I_Live_On_The_EDGE

I haven't read much martial arts lately, but here are my recommendations XD

If you can suspend some disbelief, then try: Naruto, Bleach and Inuyasha. They are not bad. (Naruto is almost purely martial arts, the other two just have some, but lots of fights and some swordwork.

Only yaoi ones.

(●￣(ｴ)￣●) um............try god of highschool

Hinomaru Zumou -- it's about sumo wrestling and it's very interesting. I really like the protagonist.
Kurogane -- about Kendo
History's Strongest Disciple Kenichi -- It concentrates on a wide variety of martial arts and it's hilarious. I have to warn you that as a shounen manga, it accentuates boobs and vaginas to the point where it's ridiculous.

Kongou Banchou is the only one I haven't seen listed and I'm not sure if its even posted here XD it's on mangahere if you wanted to know! Bad ass MC!

Don't worry, I am pretty much like yourself into seinen. Leave it to me:

Another oneshot about a shinsengumi first squadron captain (shinsengumi is a special force which was organized by the military government in Japan in 1864):

Oh and I forgot to say welcome ... I hope you'll have good time here (⌒▽⌒).

Hey thanks I thought this web was all the about the hype of yaoi. Thank God it isn't. No disrespect though. Is their anymore people in here aren't into yaoi, or is just you?

hmmm well it is a website where mainly fujoshi/ fudanshi gather.
However, who cares about the labels, this is just a manga website with many good options and it has mangas in all other genres.
Yaoi fans are just like shoujo fans, josei fans or any other type of fans ... we are all manga fans.
In addition, even if the said person is a yaoi fan, she/he might still have lists for other genres and more than one user have that. More often than not, many users here have read more than one genre or/and are still reading mangas which are labeled under other genres than yaoi.

For instance, Nasty*Gourmet has "My Blood and Gore list" which is pretty much about seinen

Another user has a "Seinen/Mature/Comedy/Smut/Ecchi" list
http://www.mangago.me/home/mangalist/3928/
etc.

Two more lists:
Seinen
http://www.mangago.me/home/mangalist/24855/

Shonen/ Sports Reads
http://www.mangago.me/home/mangalist/20312/

I follow many shoujo/josei list
http://www.mangago.me/home/people/7643/list/follow/

Aderall has also excellent lists, not only for seinen and shounen but horror too

Well, happy stay ^^

Oh my thank you for the help! Your a really cool chick for doing that. I love the Seinen list.
