Hi, I've been searching for this anime for couple years now. I watched it in early to mid 2000's. I don't remember much, but the one thing that stood out the most was the artsyle. Everything was in shades of red and orange. There was a guy with, a talking sword if I remember correctly and there might have been some jumping beetween dimensions since I remember pretty vividly a scene when the guy was on a train ( the sword might have referred to him as a doctor or something like that) and then they were in Edo period (?). It was also pretty bloody, but my childhood memory is really failling me and I have to clue where should search so I'd be really glad if you could help me. Thanks
