Majin

Majin (魔人) or also known as Magic-born is the catchall term for those who came into being from Magicules, Monsters who experienced sudden mutation, and sentient beings evolved from animals or magical beasts. They had both intelligence and reproductive ability, but only within their own subspecies. In their upper social castes existed Giants, Vampires, Demons, and other longer-lived species who are all equally capable of having offspring, although they rarely did so, since their overwhelming magic force caused them to be nigh immortal, obviating the need to leave descendants.
