I believe the anime was in the 90's. Artwork looked similar to YuYu Hakusho. Action/Martial Arts anime. One thing that I remembered most about the opening theme was that there was a part where the wind blew past him and he disappered into the with like a ninja.
The main character is a funny guys who plays around too much. He is a great fighter, moves like the wind, and in the beginning of the anime he protects this girls from a group of thugs. He also had a friend who helped him and the girl escape from a bad guy.
His friend uses feathers as weapons. From what I can remember he had red, blue, and black feathers that he used. Some feathers that he threw could turn around like boomerangs. Eventually as the main character escapes with the girl (I think), his friend fights till then end and gets killed.
The killer has this ability where he can copy other people's face by pressing the people he kill face's into the ground, pours some liquid into the ground, puts his face into the mold he created with the dead person's face and he can copy their face.
After killing the main character's friend he goes after the main character with a fake face posing as the main character's friend. That's all that I can remember.
