Mahou no Star Magical Emi EP4 - The Color of Wonder: Happiness

With Emi's recent rise in popularity, Koganei decides to expand her audience by having her debut as an idol instead of as a regular entertainer. A brief misunderstanding however has Grandma Nakamori believing that everyone will be singing, not just Emi. When the misunderstanding is revealed, Emi refuses to sing without the other Magic Carat members. Koganei begs her to debut alone in order to save his reputation, which troubles her greatly. Eventually, Mai comes up with an idea where she'll still be the main focus, but all of the troupe members can still be involved.
