Ketsueki no Kage

I am a Legendary Swordsman from my world. However, my soul has been trapped in a distorted world. But I am also becoming distorted, my armor and my sword are extremely dark, and my skin is as white as snow, even my clothes have been affected and have become extremely dark. The only thing I wanted was to get rid of this horrible nightmare and return to my world, as I always was. Even though I know that this darkness is benefiting me, because I feel my body getting stronger and my sword more powerful every day, I didn't want and never wanted this, I simply want to live an ordinary life... but, I can't give up, I have to keep fighting against these things that seem like shadows so I can get back to my world.
