Ronny Schiatto

Ronnie Sukiart is the demon summoned aboard the Advenna Avis by Maiza. He gives the entire crew the elixir of immortality and only tells Maiza how to make it just in case someone wanted to make more of it. Currently, he's disguised as a human who works as a member of the Martillo family. He is the the Martillo family's secretary.

Ronnie becomes human by request of Elmer, who wishes for Maiza to have someone to stand by him as he had recently lost his younger brother, Gretto. Ronnie, however, denies that he stayed by Maiza's side because of Elmer's wish. He said that it had nothing to do with Elmer's request and that he stayed because of his own curiosity.
