"Rascal Does Not Dream of Bunny Girl Senpai with The Pet Girl of Sakurasou" (also known as Rascal Does Not Dream of a Culture Festival Heroine) was a collaboration between Dengeki Bunko and niconico, broadcasting from February 5, 2016, as the second installment of the user-participation radio drama "Majority Vote Drama," in which the story changes based on the results of viewer polls on Niconico Live. The story is about a beauty contest held at Minegahara High School's Culture festival (in the original novel, volume 5 briefly mentions that the Culture festival was held on November 3rd, and that Sakuta got involved in trouble with the beauty contest at that time). The scenario is written by Hajime Kamoshida, and the SD illustrations are drawn by Keiji Mizoguchi. Sakuta, Mai, Kaede, Tomoe, Shoko (middle school student), and Yuma appear, and the voice cast is the same as in the later anime adaptation. The setting is after the end of the original "The Pet Girl of Sakurasou" novel, and Shiina Mashiro (voiced by Ai Kayano) from that work makes a guest appearance.
