The main character was blind and maybe he was a Swordsman because he could fight he was accompanied by a woman and she wasn't human. I remember to run he carried her on his back. She was the reason he was blind or still alive. I think he wore a blindfold and I know both of them were wearing kimonos. I've been trying to find this manga for years now and that's all I can remember.

I think this is what you're talking about Teiden Shoujo to Hanemushi no Orchestra
