Cymbalina is based on the dōbyōshi-nyōbo (銅拍子女房, "dōbyōshi lady"), one of many tsukumogami (item youkai) featured in Hyakki Yagyō picture scrolls, born from a pair of dōbyōshi (also called chappa), copper cymbals originally used in Buddhist rituals, then as musical accompaniment in kabuki plays. This youkai appears as an old hag coming out of the instrument, carrying a sutra scroll in her hands. The sound of her cymbals will curse people and force them to dance until they fall down exhausted.
"Cymbalina" may be a portmanteau of cymbal and Thumbelina, a Danish fairytale.
Cymbalina does not have a real life medal counterpart.
