Azela's Questions (1)

http://www.mangago.zone/read-manga/rurouni_kenshin/ - some romance but not the main focus

http://www.mangago.zone/read-manga/vagabond/ - probably one of the best samurai manga but there are some sex scenes

http://www.mangago.zone/read-manga/blade_of_the_immortal/

http://www.mangago.zone/read-manga/lone_wolf_cub/

http://www.mangago.zone/read-manga/claymore/ badass sword-wielding demon ladies

http://www.mangago.zone/read-manga/berserk/ - headsup this is a pretty graphic and lengthy series

http://www.mangago.zone/read-manga/shut_hell/ - not so much samurai as mongols

http://www.mangago.zone/read-manga/vinland_saga/ - not so much knights as vikings

maybe these also

http://www.mangago.zone/read-manga/the_heroic_legend_of_arslan_arakawa_hiromu/

and if youre up for an anime Record of Lodoss War is pretty good - knights and magic and the whole shebang
