Romi is a pretty normal girl at first glance, who is actually the princess of a magic kingdom, the Emotion Kingdom. She came to Earth to catch all the Teeniepings: cute but very mischievous creatures that all have a unique power attached to an emotion or a concept they represent. They like to wreak havoc in all Harmony Town, and try everything to not be caught. To catch them, Romi has to transform into a magical princess with the help of some Teeniepings. However, she must be really careful to keep her identity secret, as the people of Harmony Village do not believe in magic.
