Main character

Cain is a twenty-something-year-old man who has yet to discover he's a demon. That was until a fit of rage revealed his actual form. He's a big softie who loves nature and plants, often spending hours outside enjoying them. 

• Abel's brother
• As a child, he was adopted into a human family. He transformed into a human to match his new parents and, over time, forgot about his true self.
• He is soft-spoken and doesn't like raising his voice unless he is upset or angry.
