<p>I read a martial arts manga set in present day where a prodigal martial artist fights lots of enemies as they come along. The main character is almost unbeatable but in his youth was a bad person and so one night, while he was sleeping, his father affected his joints to limit his power to half. As stronger enemies come along he starts having trouble in his limited state and begins seeing an old lady who painfully repairs his joints to remove those limits. I'd really appreciate help finding this thing.</p>
