Zaffre is the male protagonist in Miasmon. He goes to Fracture to join the Daring Delvers. He meets Cerise, the female protagonist, before his first mission. He had a hard past, growing up in a colony that was poor and constantly beset by monsters. He learned to fight from an early age, was all too familiar with hunger, and knew what it was like to watch people he knew being killed around him. This makes him... not a fan of monsters. He's also rather pragmatic, gruff, and suspicious.
- Zaffre is a deep blue pigment derived from cobalt. Cerise, the other protagonist, is also named after a colour.
