Noelle is a kind, timid young girl who, despite remaining cheerful, is scared of pretty much everything around her, including her peers. The only people she really feels comfortable to be herself around are her bedridden father and Kris. She was sent into the Dark World unwillingly and wrapped up in Queen's quest for world domination. Her voice should sound quiet and timid, only being raised when she's forcing it or in a rare moment of confidence. She often stutters over her words when she's nervous.

She acts as one of the main protagonists, alongside Kris, Susie, and Ralsei, and helps them on their journey to the Dark Fountain.
