Dainn is the Shadow Immortal, a member of the Shadow Clan of immortals and the mastermind behind the plot to break the seal on Jormungandr. His plan required that he had a solar child and because of that sent Count to turn Ringo into a vampire. He also sent the Count to spy on Hel, but to Dainn's annoyance he fell in love with Hel. Dainn claims to be the true Dark Child, which often annoyed Sabata. Having no true physical form, Dainn possesses Red Ringo so as to be able to fight Django and Sabata, and to use him to break the seal on Jormungandr. Dainn is defeated and purified using the Piledriver, however Ringo was purified with him.
