Saint Seiya, Fuuma no Kojirou: Yasha-hen Recommendations
Both stories were created by Masami Kurumada, and share some common features, specially bloody fights, exaggerated manliness and ultimate loyalty.
In Fuuma no Kojiro you'll find several characters with almost identical appearance to the ones in Saint Seiya, since Kurumada uses the star system (popularized by Osamu Tezuka) in his works. Kojiro is Seiya counterpart (and vice versa). Ikki (Asuka Musashi) and Shun (Kirikaze) also have their doubles, and so on.
