Martial arts have served as both self-defense and a form of philosophy for thousands of years. Like various manga authors, I often wonder how martial arts would evolve in the distant future. What new offshoots of modern martial arts would develop in the centuries to come? In particular, I am interested in martial arts that combine swordsmanship and hand-to-hand techniques. In my futuristic superhuman series, I am thinking of including a character who has been training in this martial art since they were five. I even thought of a name for this martial art in Japanese.
