The Mahora Sentai Baka Rangers (まほら戦隊バカレンジャー, Mahora Task Force Baka Rangers), commonly known to western fans as Mighty Morphin Baka Rangers, are a group of students from class 2-A who repeatedly score low grades in class pop quizes and exams, resulting in them attending after-school classes for tutoring.
The group consists of Asuna Kagurazaka (Baka Red), Yue Ayase (Baka Black), Ku Fei (Baka Yellow), Makie Sasaki (Baka Pink), and Kaede Nagase (Baka Blue). The girls voted amongst themselves which colour each one received with Asuna receiving red (group leader) due to her always gaining the lowest grades of the group.
In an attempt to getting passing grades for the coming exams, the Baka Rangers and Negi entered the Library Island in search of a magical book that is said to make the reader smarter.
In the Live-action Series, they are oficially called Mahora Sentai Baka Rangers (まほら戦隊バカレンジャー) with Asuna as their leader (as opposed to the anime, where Yui was the leader) for having the lowest score amongst them.
- Baka Rangers is basically a parody of Super Sentai series and Power Rangers series.
- Although they have the lowest academic scores in their class, the Baka Rangers each have an exceptional physical ability, or in Yue's case, an ability to recall trivial information.
- During one of the preview segments in the Negima: Magister Negi Magi anime, the Baka Rangers realise that they have no enemy to combat. After much panic amongst the girls Yue suggests that Studying is their enemy.
