They are twin siblings born on the compassionate star of the Dream Nebula. They came from a faraway star country to become shining stars. Their older sister, Lala, is a bit of a crybaby and easily scared. Their younger brother, Kiki, is very curious, a bit scatterbrained and likes to play pranks.
An iconic duo if you ask me. My Melody and Kuromi and the twins are the most iconic duos across the Sanrio verse in my opinion. Anyways, an adorable set of twins, nothing else to add on.
