Arle Nadja is a magical Puyo magician who wanders through dimensions. Don't let her cute looks fool you, because she's prone to making snarky comments and will challenge anyone to a game of Puyo Puyo if she feels like it (or if someone ticks her off really hard). She also likes curry. One day, during her dimension jumping adventures, she ends up finding an intriguing world that she's never been to before. She jumps in, and finds herself in the Lunaverse! Arle finds interest in two fellow human girls with magical powers (Shantae and Reimu), and decides to join Viola Armonia! She would also later meet Cici, her apprentice!
