Cerise is the female protagonist in Miasmon. She goes to Fracture to join the Daring Delvers. She meets Zaffre, the male protagonist, before her first mission. She grew up in a bubble, so to speak; in a colony where strife, famine, crime, etc, didn't exist. She's well-educated, but naive; she's only seen monsters in books and videos before, so the monsters she sees on Fracture are novel and exciting to her. She's bright, cheery and inquisitive, since unlike Zaffre, she has no reason not to be.
- Cerise is a pinkish red colour. This may be a reference to the colour of her hair and also to her naive personality (she views the world through rose-coloured glasses). Zaffre, the other protagonist, is also named after a colour.
