Ranma ½, Asu no Yoichi! Recommendations
Asu no Yoichi is a spiritual successor to Ranma's "Martial Arts Comedy Romance" genre. There's a family dojo with sisters, the main characters practice a martial art, and there's lots of accidental falling in cleavage moments.
Both shows are comical, and include a male protagonist who have been segregated from society due to their training and everything that they experience in the city is new to them. Not to mention both of them are freeloading from a girl, both male protagonist are very strong but allow themselves to be beaten up by a specific girl.(usually the girl they like) Both male and female protagonist like each other but can't admit it.
Fighter-guy has to go live at a dojo with a girl dedicated to fighting, as well as her sisters who don't care so much for violence. Funny situations ensue, using a lot of the same jokes, etc.
Basically the same orientation: Martial arts, freeloading at dojo and entourage of bishojou.
