Chiisana Ai (Small Love) is a group composed of Maia and Zoey. They were given the name "Chiisana" (small) because of their height (They are short for their age) and that they are focused on singing songs related to the type of "love" a young child would feel. A young person, a "child" would you usually feel most love for their friends and family, and there are times you find your 1st love as a child. That is the perspective on the songs they sing.
