Three OVAs were produced prior to the series' start, solely to introduce the cast. The first two were released on DVD bundled with drama CDs, while the third was sold separately. It is uncertain if they will ever see a release outside Japan.
The first OVA adapts Chapter 1, showing Negi learning about his teaching assignment and meeting the students of Mahora Academy 2-A. It concludes with profiles of the Baka Rangers—Asuna, Makie, Yue, Ku Fei, and Kaede—as well as Ayaka. Asuna is the only girl in the class without romantic feelings for Negi.
The second OVA adapts the "love potion" incident from Chapter 2, ending with profiles of Nodoka, Konoka, the cheerleaders Misa, Madoka, and Sakurako, and Kazumi.
The third OVA adapts Chapter 13: Negi's tour of Mahora with the Narutaki twins. The tour introduces Negi to several students—Yuna, Akira, Chao, Satsuki, Satomi, Chizuru, Natsumi, and Zazie—while he misses others like Sayo, Evangeline, Chachamaru, Chisame, Misora, and Ako. After Haruna chews him out for skipping her entirely, a final scene shows Setsuna and Mana keeping watch over something on campus.
