I like series like Until Death Do Us Part, Rurouni Kenshin, Blade of the Immortal, Luck Stealer, and Skip Beat ( I know that this one is shojo, and doesn't have any action but it is really funny), and I want to find more like them, but i've been haveing trouble. Any Suggestions?

Who knew that PWM Circuits could also be butterflies.

And if you know what that is I give you props XD

have you read path of the assassin? its about hanzo hattori.
samurai deeper kyo is like rurouni kenshin but longer and more complicated. immortal regis is good as is its sequel, but i forget the name. you can look it up. soul eater is possibly the funniest series i have ever read. ubel blatt, vagabond, berserk, shin angyo onshi, vinland saga, monster, and pluto are all very good.
i got sidetracked, but everything above is a good read.

Yotsubato for comedy. Hands down.

Tokyo Crazy Paradise - By the same author as skip beat. Not quite as funny, but has more action and some parts are just hilarious.

Does the walker choose the path, or the path the walker?
