Nonononn is Sweetland's most wanted criminal. She was betrayed by Queen Purilun while the two traveled together to become magical girls. Originally from Sea Heaven, her companion is a hammerhead shark who is rarely seen in the anime.

She spent some time living in Japan with a middle class family during the 1960s, yet only appears to be about ten or fifteen years older than she appeared then. For this reason one can assume that either time passes more slowly in Sweetland than on Earth, or that the people of Sweetland age more slowly.
