Dc: Prince of Salt

Melchior an archangel, considered the strongest of the heavens, descended to earth and now he will live a life and his son will live another.

(for those who don't know it's on the cover it's Yūichirō from owari no seraph, if I'm not mistaken he's an angel, demon and human and his demon is ashura and angel I don't remember the name so I know he controls salt)
