Bleach, Gamaran Recommendations
even though Bleach has more supernatural elements, both manga include action and different sword fighting techniques. also Bleach and Gamaran have strong main character. the art is also similar.
Both mangas are (mostly) about sword fights and combat + drawing is a bit alike.
Both main characters are also hot-headed guys who won't back down even if their enemy is way beyond their capabilities.
While Bleach may contain a lot of "supernatural" elements and Gamaran not, in both you will find a lot of action and sword fights. In Gamaran, you will not only find Katanas but many different swords, in Bleach you'll find different forms of Zanpakutous.
