The idea of a traveling Swordsman intrigues me!
I would be somewhat like Jubei Kibagami. As a loner I would travel and run into bullies that need attitude adjustments. I would act bothered, but never hesitate to slay evil and stop injustice. I would contract myself out as a bodyguard, kind of like Akira Kurasawa's "Yojimbo".
My weakness would be "kawaii" girls, which in turn could be bad if one was an assassin or felt it was necessary to inflict painful compliance like what Kirie Kojima does to Kazuharu Fukuyama in Girls Bravo!
