Twelve-Winged Dark Seraphim
Wrong Theory Time!!! I think that Han Sen resisting is what will make him superior to "real humans" he will only be able to utilize the blue blood while running the blood pulse sutra ane when he's not, he'll be able to use everything else. Or he'll evolve beyond the limit of the blue blood and when he "blesses" people, they will gain the benefit of the power he can't quite control...... OR that black Super Gene that lies dormant will awaken and absorb the blue blood power and become the Sacred Leader reborn! What do you think??
