The MC could absord some negative energies or something, and if he did he would either have to endure pain or something, or *cough* use the bodies of women to help him. He also obtained some inheritance that had something to do with stars. AAAAND his father got adopted into a small clan i think, while his actual clan was like a hugeass powerhouse far away
God Of Slaughter, I think. He absorbs negative energy(gets horny cuz of it), the star martial spirit and his actual clan is very big.
