A hero with no name is a strong pacifist. The why is not important right now.
The problem: he lives in a world of kung-fu where just being quiet and polite to live happily can't work for long. This is not a society where the violence is a distant thing and only in hands of army/police.
Plus, he has a goal, and some other people don't wanna let him achieve it... ACTIVELY!
Confrontation CAN BE DELAYED with negotiation, talking, and other soft-skills, but sooner or later, violence will be required.
Because of his goal, he can't just take the damage or accept death for his ideals.
Now, I need a way for him to "fight" without turning into a martial pacifist (somebody that only fights as last resort but still actively uses violence, for example, Batman who fights but just avoids killing).
I'm looking not only for a combat system but also the strategy, tactics, and philosophy that allow him to succeed (ie: a martial art).
Also, because him is totally aware of the bad situation and conflicting goals of this setup, the hero knows that he must become one of the best "fighters" in the world to have a chance. When things start to unroll, he must be ready for the challenge.
- No magic based solution. I want a realistic-ish martial arts. However, you are free to suggest things that stretch a little real-based combat systems (ie: Like in Kenichi) where the combat looks plausible, or if the style requires some upgrades of humanity to work (like Daredevil but not like Thor).
- The time period is like ancient Edo/Japan. Everyone use classic martial arts and weapons. This idiot is the only one that refuses to use it properly, you know?
- He has companions with more flexible morality. He hates that and uses all his strength to avoid relying on them. He is a pacifist that wishes everyone else would become one, too. He is unwilling to just let others do his fighting.
- The hero will not actively use violence and prefers to not use anything that could lead to bad injuries or be considered a weapon first, like swords. Sticks or anything else like that could be ok, but you must explain how he uses it without crushing skulls.
- He avoid fights but does not hesitate to help others. Unfortunately, this means not much time for negotiations..
- Any other creative solutions, such as use of smoke grenades, but such solutions must be integrated into the martial art. I have designed systems where my hero could dodge, run, and evade but still found the need to apply force somehow...
- The style must work against a small number of opponents, like that pesky gang that is trying to hurt an old lady.
- Is ok to make him taller, stronger, faster, or any other thing that could reduce the disbelief of his "fights"
