the manga was released in the US around the 90's, it takes place during the iga/yagyu war. one of the main characters, where's a basic monk outfit, has two big buckteeth, and his eyes are mismatched. the story itself follows a ninja of the, i believe, yagyu clan. his hairstyle is similar to the ninja scroll character, jubei yagyu. BUT IT IS NOT NINJA SCROLL. if anyone knows this series i'd appreciate it.
