Rainbow Bubblegem

Mermaid Princess Purple longs to see the human world and secretly ventures onto land with help from her guardian. During the adventure, the magical Rainbow Bubblegem is shattered, scattering its precious fragments across the surface world and creating a crisis that cannot be solved from beneath the sea.

Queen Whitegold sends seven mermaid princesses onto land to recover the missing pieces. Living as human schoolgirls, they must hide their true identities, learn the unfamiliar rhythms of life above the water, and work together before the sea witch's servants collect the Bubblegem fragments for themselves.
