 If you liked
Asu no Yoichi!

 ...then you might like
Kure-nai
|
Both Asu no Yoichi and Kure-nai revolve around the marial arts world, though Kure-nai is much darker and Asu no Yoichi is much more comedic. Both have the main protagonist as being the centre of attenetion with a harem-esque feel. Both manga have the protagonist battling to get stronger to protect what is important to them. So, I believe that if you enjoy one you'll enjoy the other.
