Mahou no Star Magical Emi EP13 - The Home Tutor is 16 Years Old

Due to all her time spent playing around instead of studying, Mai has to rush to complete her summer homework and get her grades up, especially after her father ups the ante by forbidding her from doing magic until she's done. Mai's mother enlists Shou to tutor her, but Mai becomes restless when she finds out that Magic Carat will lose their TV spot if Emi misses the broadcast. When Shou leaves, Mai takes her chance to sneak out and transform, assumedly behind his back. However, Shou reveals to Emi that he'd actually advocated for Mai to her father, so that she could attend the show and stop worrying for Magic Carat. This brings the two a bit closer, and Mai seems to be developing feelings for him.
