This was one of my favaurite anime..... " History Strongest Disciple Kenichi ". It was a very funny anime and full of fighting scene.
This anime focus on Kenichi Shirahama (Shirahama Kenichi), an average 15-year-old weakling student, whose life is upended with the appearance of the naive, beautiful, and strong transfer student, Miu Furinji. When the weak Kenichi witnesses Miu's skill in martial arts in one incident, he join the Ryozanpaku dojo, a gethering place of those who are truly strong, whitch coincidentally also happen to be Miu's home.
This anime have 50 chapter (you can view new chapter/story in its manga)
