Magister Negi Kore (1x14)

The girls hold a beauty contest to measure Negi's attraction to them. Hosted by Ayaka, the event features Negi strapped to a chair and the girls in their swimwear. When Asuna inadvertently enters the competition, she wins by a landslide, much to Ayaka's chagrin. Elsewhere in the school, the cheerleaders Misa, Madoka and Sakurako vanish, along with all memory of them.
