Charlie has always felt that there was something Mysterious about Akala Island, and after having a dream of the Akala Island Guardian, she declared it her duty to hunt down Tapu Lele and discover why they were so 'in tune'. While her initial motives lay in the name of science, she soon comes to realise there's something far bigger Tapu Lele has planned for Charlie. Something far more complex than 'in the name of science'.
