With their help, Rainbow leads her companions to form the “Rainbow Guardians”, standing together against the invasion of negative emotions. However, the dark energy continues to grow stronger, and uncovering the mastermind behind it becomes urgent. What Rainbow never expected is that the one pulling the strings has been by her side all along.
