Ami Maeshima will voice Karen in the anime Koujo Denka no Kateikyoushi (Private Tutor to the Duke's Daughter) and also sing the opening theme, "Wish for you." Karen is Allen's stepsister. Maeshima expresses her dedication to both roles. A giveaway campaign for a signed poster is running on the official X account (@koujo_anime). The anime, about Allen tutoring the princess Tina, will premiere in July.
