While looking for clues about his missing father Nagi, Negi Springfield becomes the English and homeroom teacher for Mahora Academy Class 2A (later 3A).

To help Negi confront Eva, Asuna agrees to become his temporary partner by performing a "Pactio", a kind of magical contract sealed with a kiss.

Kotaro also joins Negi against Wilheim, an old evil from the past who like Fate Averruncus, seems to be a pawn of an even stronger enemy.

During Mahora's cultural festival, Negi manages to partake in simultaneous events thanks to his student Chao Lingshen's latest invention, the time machine Casseopeia.

One of these events is the "Mahora Martial Arts Tournament" where he confronts a series of increasingly stronger enemies including a former member of "Ala Rubra" (Crimson Wing), a legendary brigade led by his father.

After the tournament, Negi takes part in more activities at the festival until Chao she reveals herself as a time-traveler who claims she must change the present to avert a great catastrophe in the future.

After meeting Jack Rakan, another member of Ala Rubra, Negi decides to train in order to become stronger and specializes in Dark Magic, like Evangeline.

Later Negi has an encounter with Kurt Gödel, a former member of Ala Rubra who reveals to him the story of his parents including how his mother was unjustly tried and sentenced to death before being saved by Nagi at the brink of her execution.

During another clash with Fate, Negi also learns that the main objective of his group "Cosmo Entelecheia" is to make use of Asuna's secret powers to erase the magically created inhabitants of Mundus Magicus and transfer the rest of its population to Earth before it eventually collapses.

By joining forces with the various armies of the Magic World, the members of Ala Alba storm Cosmo Entelecheia's stronghold where Asuna and Anya are being held captive, to stop their plans.

During the confrontation a magic gate is opened to Earth just above Mahora, having Negi's remaining students who stayed behind along with the academy's faculty members joining the fight.

After rescuing Asuna and convincing Fate to accept a plan to save the people of the Magic World without the need of any sacrifices, Negi discovers that the true leader of Cosmo Entelecheia is none other than his father Nagi, possessed by the Mage of the Beginning, who vanishes after asking his son to look for him and release him once and for all.
