I've been reading a lot of martial arts manga lately, including Souten no Ken, the Breaker, Veritas.. all good stuff, I suggest you give them a read, but reading them actually even inspired a character of mine, and I want to put him to use, but I also wanted to know if people were interested in doing the same! Humans are capable of stretching the limits of humans using chi and various forms of martial arts, so I thought I'd make a modern-era set RP with human characters who only rely on what their training in a particular art has given them rather than be some kind of super powered demon...
Not that the martial arts doesn't imply some sort of super strength.
