Progenitor Path

Isaac, a F-Rank Hunter, was a normal 20 year old man, he grew up in a well family, a loving family that helped him throughout his life. He somewhat considered himself as 'nomal' because there was only a slight difference between him and a normal human. Little did Isaac know that he was 'special' amongst his family, what he carries within himself is blood that is a very rare type of blood. A blood that... is coveted by a certain race.
